GradeShift & GradeShift UDL

Use a CSL Signal Analyser to determine if sufficient base stations are available at the site and that they can supply sufficient signal strength. This will determine the optimum location for the DualCom’s aerial to be mounted.

SITING THE AERIAL

DO…

• INSTALL VERTICALLY IN AN OPEN SPACE.
• COMPLETE A SIGNAL TEST BEFORE INSTALLING IN THE FINAL POSITION.

DON’T…

• INSTALL CLOSE TO METAL OR SOURCES OF INTERFERENCE, I.E. WIRING,
• LIGHTING, ELECTRICAL INSTALLATIONS, COMPUTERS, MONITORS, ROUTERS & OTHER EQUIPMENT.

a – Ensure the aerial is mounted and connected in the correct position to achieve maximum signal strength. Apply power and wait for 5-8 minutes for the unit to connect to the network and download its programming file. Once completed the Green Signal Strength LED should be on or flashing, indicating an acceptable signal, the Red Fault LED should be off and the Blue Ready LED will be on. A percentage will also be shown on the SSD (Seven Segment Display) which should be 40% or higher. Now the GradeShift can be located into a suitable enclosure for the grade of installation.

b – Wire the input triggers, attach the RS232/485 cable or connect the Control Panel’s Digi-Modem PSTN terminals to the GradeShift’s Dial Capture terminals (refer to wiring diagrams in Section 2 of this document). For a dual path device remember to connect for PSTN or LAN.

c – Connect the fault output terminals to the Control Panel as required (refer to wiring diagrams in Step 6 of this document).

d – Power down the the Power Supply Unit (PSU), connect 9-30volts DC supply to the GradeShift’s power terminals and repower the PSU. Note that any voltage below 12v will indicate a low battery warning.

e – For installations using Dial Capture no GradeShift configuration is required. Simply check that your Digi-Modem has an ARC telephone number (ie 01) and an account number (ie 1234), select your signalling format, connect the GradeShift and test.

f – For pin triggering installations, ensure that the panel is in its normal state then press and hold the TEST/LEARN button for 3 seconds until the Green Signal Strength LED and the Yellow Communications LED flash alternately. Please note it is recommended that this step is not carried out until the instructions above have been completed.

IF USING A SEPARATE PSU TO POWER THE GRADESHIFT, MAKE SURE THE 0V IS COMMON BETWEEN THE PSU AND THE CONTROL PANEL.

To send test signals, tap the TEST/LEARN button (less than 1 second). The 7 SSD should change to c1, c2, c3, A. (A = the Gemini Platform acknowledges the alarm signal). Simultaneously, the Yellow Communications LED indicates comms progress. If available, GradeShift will test the secondary (wired) path using C1, C2, C3, A to indicate successful communication.

If the test is not successful the Red Fault LED will light for 2-3 seconds at the end of the sequence. The GradeShift will make multiple call attempts if unsuccessful.

To self-learn the inputs, push the TEST/LEARN button for 3-5 seconds. ‘Pi’ will be displayed during the self-learn process.

Once you have successfully tested your GradeShift, make sure that you check with your ARC to see that they are receiving signals. This can be achieved by calling your ARC or using their web-based secure platform.

IF YOU HAVE PURCHASED A DUAL PATH DEVICE YOU MUST ENSURE BOTH PATHS ARE CONNECTED BEFORE LEAVING SITE.

LINE FAULT

Ensure you wire the fault output in accordance with the standard you wish to adhere to.

FAIL TO COMMUNICATE MONITORING USING DIAL CAPTURE

If you want to monitor the Dial Capture connection, connect an output configured as PSTN line fault on your Control Panel to one of GradeShift’s inputs. Designate that input as Dial Capture fail at your ARC. For wiring instructions see step 6

RS232/485 – for installations using RS232 or RS485 simply follow the wiring diagrams in step 6.

LAN – For installations using LAN as a communication path connect a Cat5 (or higher).

GRADESHIFT WILL AUTOMATICALLY LEARN WHETHER THE PSTN LINE REQUIRES A 9 TO DIAL OUT AND WILL SAVE THE SEQUENCE TO ITS CONFIGURATION. IF THE PSTN CHANGES AND NO LONGER REQUIRES A 9 TO DIAL OUT GRADESHIFT WILL REVERT THE CHANGES.

PIN TRIGGERING

In the operation, GradeShift is triggered by applying or removing zero volts to the input terminals 1-12. No external pull-up resistors will be required. This is generally achieved via the digital communicator outputs of an intruder alarm or similar Control Panel. GradeShift will signal alarm conditions and will generate the relevant messages and forward them via Gemini to the ARC. Installers are advised that the intended use should avoid situations where the rate of triggering exceeds the rate at which messages may be sent to, or received by, the ARC receiver.

DIAL CAPTURE

In this operation, GradeShift simulates and replaces the phone line connection to the Control Panel’s Digi-Modem.

The Control Panel’s Digi-Modem must use one of the following alarm formats: Fast Format, Contact ID or SIA. In the event the Control Panel needs to send a signal to the ARC, GradeShift will capture the message and forward it, via Gemini, to the ARC. The Digi-Modem must have an ARC telephone number (ie 01) and account number (ie 1234) programmed for Dial Capture to work.

If you want to monitor the Dial Capture connection, you will need to connect an output configured as a PSTN line fault on your Control Panel to one of GradeShift’s inputs. That input then needs to be designated as Dial Capture Fail at your ARC.

For further instructions on Control Panel programming please review the how to guides on the Installer Zone

Q – The Red Fault LED is continuously flashing, what does this mean?

A. This happens when the unit is first powered and needs to download its configuration file from the Gemini Platform which can take 5-8 minutes. You must ensure that the Yellow Service (SVC) LED is flashing every 3-5 seconds, which indicates that the unit is connected to the mobile network.

Q – The GradeShift repeats the ‘power-up’ sequence but never completes it.

A. The power supply has a low output voltage or is unable to supply the current required by the GradeShift when it is activated. Check the power supply with a multimeter. Also, test the GradeShift’s operation when powered by a ‘known good’ 12-volt battery.

Q -The Red Fault LED is on, what is the problem?

A. Please refer to the error code on the SSD and the error code list at the end of this document.

Q -Triggering via ‘Dial Capture’ does not seem to work.

A. During communication between the Control Panel and the GradeShift, the display should show ‘DC’. If ‘DC’ is displayed, but c1, c2, c3, A is not, the panel may not be compatible or is configured to send a protocol that GradeShift does not recognise. If available, check the Control Panel’s programming and select an alternate signalling format. Please check our online compatibility table for the latest list of compatible Control Panels and formats: www.csl-group.com.

Q – The ARC is not receiving messages.

A. In most cases the GradeShift will explain the reason a signal cannot be sent to your ARC using an error code shown on the SSD. If, after trying to rectify the displayed fault, the GradeShift can still not transmit to your ARC please contact CSL Technical Support.

CRITICAL ERRORS

To alert the User and Installer to critical error conditions, after the normal sounder beeps have timed out the GradeShift unit will continue to beep once every 5 minutes.

MOUNTING

This device should be mounted inside the Fire Alarm Panel or inside a separate powered housing using, the sticky mounting pads supplied. Enclosure requirements for the GradeShift UDL Fire are the same as for the Fire Alarm Panel itself. The enclosure must provide the facility to indicate the state of the fault and acknowledge outputs on the device. For Fire Alarm Panels, the enclosure must meet the requirements of EN54-21 7.3 (e.g. IP30 or above) and the supplied sticker should be applied to the outside of the housing.

SECONDARY (WIRED PATH) CONNECTION OPTIONS

The PSTN connection requires an analogue telephone line. Connecting other telecoms equipment in parallel to the analogue telephone line used by this device can stop the unit sending polling calls and alarm calls to an Alarm Receiving Centre. Parallel connection should never be used for this device when it is used in a Fire system application. The PSTN line should be supplied as ‘outgoing calls only’, i.e. incoming ringing barred. The PSTN line should also be ex-directory and connected to this device only. Other equipment can be connected to the A1 & B1 terminals (i.e. series connection) to make outgoing calls only. Modifications to the telephone or data provision (including changes to the local IT network when a LAN connection is used) might prevent or hinder the transmission of alarm information. Additionally, this could cause false alerts which might cause customer inconvenience and/or (where it is provided) result in withdrawal of emergency service response.

GRADESHIFT UDL FIRE IS SENT OUT IN EN54-21 TYPE 2 CONFIGURATION (GPRS/PSTN). THIS IS NOT CONFIGURABLE BY THE INSTALLER

The interface to the Fire Control Equipment should be via inputs (pins) and relay outputs, as described below. The DualCom’s ‘Dial Capture’ interface that emulates a PSTN line shall not be used, as it does not provide adequate status signalling back to the control equipment.

• AUX Relay Output: used for transmitting fire alarm ACK signals to the CIE.

• Normally Closed (N/C) Fault Relay Output: used for transmitting fault warning signals to the CIE. This relay will remain open during normal operation.

• Input 11: used for receiving the Fire Alarm/Restore signal from the CIE.

• Input 12: used for receiving Fault/Restore signal from the CIE.

• Input 1-10: used for receiving PIN inputs from any other device (i.e. security CIE). PINs 1-10 take a lower priority than 11-12 when signalling.

The alarm codes generated by these inputs are as follows:

SIA	CONTACT ID	FAST FORMAT
Pin 11: FA8011/FH8011	Pin 11: Event 110 group 0 zone 11	Pin 11 Channel 11
Pin 11: FA8011/FH8011	Pin 12: Event 373 group 0 zone 12	Pin 12 Channel 12

As default, inputs 11 and 12 are configured as digital inputs. They can be set up as End of Line (EOL) detection, Fully Supervised Loop (FSL) or digital inputs.

For FSL mode, a 10K and 2K2 end of line resistors should be fitted for detection of open circuit and short circuit. For EOL mode, a 10K end of line resistor should be fitted for detection of open circuit:

Simple line drawing showing inputs for Fire

Inputs 11 and 12 can be configured for either EOL and FSL using the programmer menu:

• A button 4 times to P

• B button 3 times to Pi

• A button 5 times to PF

• B button 3 times to Fd

Use B button to scroll:

• Fd = DIGITAL

• FE = EOL

• FF = FSL

Press A button to select mode.

PINS 1 – 10 CAN BE TRIGGERED BUT THEY WILL NOT SEND FIRE ALARM/FAULT SIGNALS.

For FSL or EOL, were the negative supply (0V) to the panel relay common and the panel N/C terminal to the DualCom input pin with the 10K resistor in parallel.

For Digital, wire the negative supply to the panel relay common and the panel N/O terminal to the DualCom input.

FAULT REPORTING & DUAL PATH OPERATION

To meet the EN54-21 requirements for monitoring on Type 1 and Type 2 Fire systems this device sends regular polling calls to the Gemini Network on all connected and active transmission paths. The Installer shall ensure that a reporting action has been agreed with the ARC for all alarm codes, transmission path failure notifications and Polling failure reports from the Gemini Platform.

GRADESHIFT UDL FIRE HAS BEEN DESIGNED TO WORK AS A DUAL PATH SIGNALLING DEVICE, INSTALLATIONS THAT USE ONLY 1 SIGNALLING PATH WILL NOT MEET THE SPECIFIED DP2 FAULT REPORTING TIMES.

RELAYS

The Acknowledgment and Fault signals are triggered by the AUX Relay and Fault Relay respectively. Depending on how the CIE input works (active high or active low), please wire them as follows:

FAULT RELAYS

The fault relay labelled NC must be used. The device will ensure this remains open in a No Fault condition and it will close when any of the following conditions are met:

1 – The power is removed.

2– There is a short circuit in any of the interconnections between the CIE and the device. (FSL configuration only)

3 – There is an open circuit in any of the interconnections between the CIE and the device.
(For FSL and EOL configuration)

4 – An acknowledgement has not been received from the Gemini Platform within the allotted time after a Fire Alarm has been sent within 240 seconds (type 2), 100 seconds (Type 1)

5 – There are no transmission paths available. Please note, all available paths must fail before a fault warning is given.

6 -There is a watchdog event (program monitoring).

7 – There is a memory (CRC) monitoring fault.

A FIRE ALARM WILL NOT RESTORE UNTIL ALL FAULTS (WIRING OR PANEL) ARE CLEARED

FAULT RELAY SHOULD BE WIRED TO THE FIRE PANEL FAULT INPUT OR TO A SEPARATE LIGHT EMITTING INDICATOR AS REQUIRED BY EN54-21 5.3.B

The acknowledgement relay (ACK) is normally open. It closes when an acknowledgement of a Fire Alarm is received from the Gemini Platform. It is opened again when an acknowledgment of the Fire Alarm Restore signal is received from the Gemini Platform.

THE ACK RELAY WILL CLOSE EVEN IF AN ACKNOWLEDGMENT IS RECEIVED AFTER THE ALLOTTED TIME OF 240 SECONDS (TYPE 2) HAS EXPIRED, AS IN POINT 4 ABOVE.

ACKNOWLEDGEMENT RELAY (ACK)

The acknowledgement relay should be used to indicate the successful receipt of a Gemini Platform acknowledgement either at the Fire Alarm Panel or by a separate light emitting indicator, as required by EN54-21 5.3.a

When ADSL (Broadband) digital data is supplied on a normal PSTN telephone line then an ADSL (Broadband) Filter must be fitted between that telephone line and each item of ‘non-digital equipment because:

1 – The operation of ‘non-digital equipment may be disrupted or completely inhibited if ADSL (Broadband) digital data is allowed into it from the telephone line.

2 – The operation of the ADSL (Broadband) equipment may be disrupted or completely inhibited by the connection of unfiltered ‘non-digital equipment to the telephone line. ‘Non-digital’ equipment means anything that can be used on a normal analogue PSTN telephone line, e.g. a Phone, Fax, DualCom, Control Panel Digi-Modem.

In the event you are using two separate power supplies, one for the alarm panel and the other for the DualCom – ensure there is a common 0v across both power supplies. I.E. Wire the 0v of one power supply to the other power supply’s 0v.

Ensuring both the alarm panel and the DualCom have a common negative (0v) supplied will prevent any unexpected behaviours, including random triggers.

Use the A & B Buttons to check that the PSTN path is active. (See page 6 in the Quick Guide)

Check that the PSTN line is properly connected. Check with a multi-meter that approximately 50 volts DC is present across the PSTN terminals marked A and B. Check that when the PSTN path is triggered on the DualCom, the voltage across the telephone line A and B terminals drops to between 6v and 14v DC.

Connect a telephone to the PSTN line and make a call to ensure that it is fully functional. If you can make outgoing calls on the PSTN line, then try the receiver number programmed within the DualCom. You can get this number by calling the CSL Technical Support team on +44 1895 474 444. If your call goes through to the receiver number, you should hear a fax tone.

Disconnect any other equipment that is using the same PSTN line to ensure that it is not inhibiting the DualCom. Where ADSL (Broadband) digital signals are on the telephone line ensure that an ADSL (Broadband) filter is fitted between the DualCom and the PSTN line.

For further support, please contact the CSL Technical Support team on +44 1895 474 444. Alternatively, you can email support@csl-group.com.

Check using the 7-segment display that the radio signal strength is sufficient (40 or greater) and that the signal strength on the display is not flashing on and off. If the signal strength is flashing on and off on the display, then please contact CSL Technical Support for assistance.

Check with a multi-meter that the voltage supply to the DualCom is correct and does not dip when the DualCom is signalling. The DualCom requires voltage between 9v – 30v. If the voltage supply is good, then please check the mA supply – the DualCom will draw 20 mA if idle and 200mA when signalling. If inadequate mA is being supplied to the DualCom during either state, then this would indicate an issue with the power supply.

For further support, please contact the CSL Technical Support team on +44 1895 474 444. Alternatively, you can email support@csl-group.com.

Check, using the LEDs that no LAN path faults exist.

Check that the LAN has a route to the Internet. Ensure that Firewalls, Routers etc will allow external access. Refer to IT staff on site.

Check that the LAN has a DHCP Server function. The LAN card requires this when first connected to the LAN. Refer to IT staff on site. Check with a meter that the voltage supply to the DualCom is correct and does not dip when the DualCom is signalling.

Yes. The GradeShift UDL supports a secondary path in addition to the primary GSM path. The following Gradeshift UDL variants are available:

GradeShift UDL GSM only.
GradeShift UDL GSM + LAN.
GradeShift UDL GSM + PSTN (discontinued due to All IP & the Copper Switch-Off).

Important Note: The GradeShift UDL only supports one secondary path at a time. I.e. It cannot support GSM + LAN + PSTN. It can only support GSM + LAN or GSM + PSTN.

The GSM path will always be the primary signalling path. The LAN or PSTN path will always be the secondary path. If the GSM path fails to signal, the LAN or the PSTN path will take over.

Important Note: The GradeShift UDL only supports one secondary path at a time. I.e. It cannot support GSM + LAN + PSTN. It can only support GSM + LAN or GSM + PSTN.

Every time the GradeShift UDL signals, it will display a series of characters on the segment display to show the signalling steps. The best way to test if the paths are working is to get the GradeShift UDL to send a test signal on all working paths.

To send a test signal on all working paths, simply tap the small play button on the front of the unit.

Poll signals will show a small c1, c2, c3 and then a flashing A. The characters will be on the upper segment of the display.
GSM signals will show a small c1, c2, c3 and then a flashing A. The characters will be on the lower segment of the display.

LAN or PSTN signals will show a large C1, C2, C3 and flashing A. The characters will take up both the upper and lower segments, making the secondary path signalling easy to distinguish from the GSM.

Important Note: During signalling, if the segment display does not progress all the way through the steps, this would mean the signalling path has failed to signal out. E.g. If the segment display shows a small c1, but does not progress to c2, c3 then a flashing A, this would mean there was an issue with the GSM path’s ability to signal out.

The GradeShift UDL supports 3 connection methods, and each connection method supports 3 signalling protocols.

Connection methods:

Hardwired Pins
Dial Capture (Connects to the panel Digi Modem)
Serial RS-485 (Connects to Honeywell and Orisec panel data lines)

Signalling protocols:

Fast Format

Enter engineer mode on the GradeShift UDL to lower path fail times. Then disconnect the path you want to force into fail.

To enter engineer mode:

Press A until “t” then press B twice. Engineer mode will last for 10 minutes then exits out automatically, returning the path fail times back to normal.

By default, the pins are configured for “Negative Applied”. For best results, please run a self-learn on the pins once you have wired in all the pins you need.

To run a self-learn:

Press and hold the small play button on the front of the unit until the letters “Pi” are displayed on the screen, then let go.

The pin learn will detect all the pin wirings and match the pin config to your panel’s outputs.

E.g. If your intruder alarm that wires into pin 3 is set for “Negative Removed”, the self-learn will invert pin 3 on the GradeShift UDL and change it from “Negative Applied” to “Negative Removed” to match your intruder alarm.

Important Note: The GradeShift UDL pins only support Negative voltage. Positive cannot be used.
