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.

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.

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.

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).

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.

ERROR CODES

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.

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:

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:

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.

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.

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.

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.

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
