GradeShift Pro

The DualCom Pro Range offers Installers easier, faster installation of a professional signalling system with even greater resilience, plus access to CSL Live, our brand new ordering and management portal.

Using the onboard serial connections or pin triggering, DualCom Pro is compatible with a wide range of control equipment including systems installed to EN50136 & PD6662. The range consists of DigiAir Pro – our single path solution that utilises a Radio path to signal an alarm; and GradeShift Pro – our dual path solution that utilises a combination of two Radio paths or one Radio and one LAN path to signal an alarm.

It’s as Easy as 1, 2, 3

Most DualCom Pro units are ready to go after these few simple steps

Variants with Radio

Use a Signal Analyser (available from the CSL Installer Shop) to determine if enough base stations (2 or more) are available at the site and that they can supply sufficient signal strength (30% and above). This will determine the optimum location for the DualCom’s aerial to be mounted.

If you do not have a Signal Analyser we recommend powering up the DualCom Pro, connecting the aerial/s, going through the commissioning process and checking the signal strength before permanently fitting the aerial. We recommend signal strength on the DualCom Pro should be 3 (30%) or above.

Variants with LAN

Ensure there is a LAN port adjacent to the alarm panel. DualCom Pro uses DHCP as default, fixed IP settings can be added/amended in My Base through the CSL Live App/Web Portal or via the A & B buttons. Fit the Ethernet Cable to the device (as per Figure 2) and connect to the customer’s router. Ensure the customer’s LAN socket is live and has the correct network setting, as per below:

• Port 50561 open for outbound traffic
• NAT enabled
• UDP data

The LED on the LAN connector adaptor will flash green to indicate connection.

DualCom Pro must be installed within an enclosure suitable for the installation certification. The unit should be fixed securely using the adhesive pads supplied or via the screw fixings accessible by removing the lid.
Once fitted, ensure:

1. As required the aerial/aerials are connected and/or the LAN connector is installed
2. The alarm panel or PSU is powered down, then connect the DualCom Pro PWR +ve and –ve terminals to the 12/24V DC output of the control equipment
3. If required, connect the serial cable – RS485, RS232 or TTL (panel dependent) – see Figure 1 for more information
4. Connect any hardwired alarms into the device – see Figure 4
5. Connect the fault output
6. Restore power to the alarm panel or PSU

On power-up, the DualCom Pro will automatically contact the Gemini Global Platform to perform its commissioning process, which will take up to 5-8 minutes. During this time the display will show ‘N’ to indicate it is a new device, followed by ‘C’ as commissioning is in progress and ‘R’ to indicate it is fully commissioned and ready for use.

During this process you may see ‘SIM NOT READY’ displayed. This is normal and will clear once completed.

LEDs

Figure 3 – LEDs ON INITIAL POWER UP

LED 1 – POWER	LED 2 – COMMUNICATION PATH	LED 3 – COMMISIONING
No light = The DualCom Pro does not have power	No Light = No paths working yet or the DualCom Pro does not have power	No Light = No communication path found
Green Solid Light = The DualCom Pro is powered and is running valid firmware	Amber Solid Light = One communication path is working	Amber Flashing Light = Communication path found
	Green Solid Light = Two communication paths are working	Green Flashing Light = Commissioning Server found, contacting the Alarm Server
		Green Solid Light = Fully commissioned

CHECKING SIGNAL STRENGTH

Signal strengths can be easily checked via the My Base App for each path. To view the signal strength on DualCom Pro, wait for the device to commission. The display will read out the RAT (Radio Access Technology) and the signal strength of the primary Radio Path (i.e. GSM1 4G 8). If you have a secondary radio module, toggle DIP switch 4 to show the RAT and signal strength of GSM 2 (ie GSM2 4G 6).

PIN TRIGGERING

For this operation the device is triggered by removing or applying zero volts to input terminals 1-8. No external pull-up resistors will be required. This is generally achieved via the digital communicator outputs of a control panel. The unit will signal alarm conditions and will generate the relevant messages and forward them via the Gemini Global Platform to the ARC. Installers are advised that the intended use should avoid situations where the rate of trigger exceeds the rate at which messages are received at the ARC receiver.

Figure 4 – Example of pin triggering wiring

PIN INPUT CONFIGURATION

If you need to change the input from negative removed to negative applied, this can be done on CSL Live via My Base. If you need to use positive applied/removed you will need to change the pin profile on My Base and manually change the bias on the device using the Self Learn feature:

• Ensure all required pins are in a restore/quiescent state and you are out of the device menu
• Press and hold the C button until L appears on the display
• Release the C button
• The display will confirm successful operation by displaying ‘LEARN OK’

OUTPUTS

Output default is normally open. Output 1A + 1B are volt free contacts, that are normally open and configured to indicate path fail conditions to the control panel.

IF THE DEVICE IS POWERED BY 24V (FIRE PANEL), + TERMINAL SHOWN WILL STILL DELIVER 12V.

Output 2 is a single wire switch negative output with a 100mA max current. As default, this output is unused but is configurable by calling CSL Technical Support.

DIAL CAPTURE

DualCom Pro can be fitted with an optional Modem Capture Module (purchased separately – part number CS.1.402). When using this module, it must be plugged into the main board via the connector shown on
Figure 1.

If you are using a dual radio variant of the DualCom Pro, the plug-on radio module must be removed and refitted into the Tamper Proof Case and connected via the RS422 BUS connections on both boards. With the radio module removed the Modem Capture Module can be fitted onto the DualCom Pro. Both the Modem Capture Module and Tamper Proof Case (part number CS.1.500) can be purchased via the CSL Installer Shop. Please follow the instructions provided within the product.

PANEL CONNECTION

Your device will come pre-configured without a panel connection (pins only). To enable serial connection to a control panel, go to My Base and select the panel type.

Alternatively, contact CSL Technical Support via support@csl-group.com or call +44 (0)1895 4744 44.

SERIAL / RS232 / 485 / TTL PANEL CONNECTIONS

As standard, the DualCom Pro range is supplied with a serial cable compatible with Honeywell (RS485), Orisec (TTL), Pyronix (RS232) and Texecom (TTL) panels. Other types may require an additional cable/plug in purchased on our Installer Shop – see Figure 7 for more information.

Figure 6 – Panel Connection Information

For Risco, Eaton and UTC, please purchase the relevant cable from the CSL Installer shop. For other connections or further instructions on Control Panel programming please review the Panel Guides on the Installer Zone of our website: www.csl-group.com/uk/installer-zone-panel-guides

Figure 7 – Serial Cable (RS232/485/TTL)

Please also ensure that you put your device on test with the ARC and perform a full range of test signals from your control equipment. DualCom Pro paths can be tested using the following method:

• Tap button A until S is shown
• Tap button C to indicate Path Test
• The display will read out PATH TEST and return to Menu S for 30 seconds before returning to signal strength

Once you have successfully tested your device, 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.

RADIO TROUBLESHOOTING

How can I fail my signalling paths without having to disconnect them?

To fail each path select menu options N or O
• Menu N – Fails primary path
• Menu O – Fails secondary path
Using the A or B button scroll until you see menu N or O on the display, then press and hold the C button until you see (_). Press the A or B buttons to toggle between Y & N, then press C to select the option.

Y = Yes, fail the path.
N = Normal, restore the failed path.

“Y” will only fail the path for a total of 15 minutes.

What does the flashing dot in the right-hand side of the display indicate?

The flashing dot in the right-hand corner of the display indicates that DualCom Pro is actively transmitting data.

How can I check the signal strength of each radio module?

You can check the signal strength of each radio module on a commisioned device via the My Base App. Alternatively you can toggle between the signal strength of each radio module, move DIP Switch 4 of the secondary radio module to ON or OFF (opposite position). The display of the DualCom Pro will read GSM 1 or GSM 2 followed by the Radio Access Technology (RAT) and signal strength between 1-10 (10-100%) dependant on the radio module.

Does my unit have a roaming SIM?

Yes, all variants of DualCom Pro devices come with at least 2 Roaming 4G SIMs

If the signal strength of my DualCom Pro is under 3 (30%) what can I do to improve my signal strength?

For all radio variants:

• Avoid coiling the aerial cable
• Move the aerial away from electrical equipment/wiring
• Move the aerial to a higher point in the property or closer to a window/door

Where you are using a dual radio variant, it is possible to purchase an additional Radio/Wi-Fi Module Enclosure with in-built aerials. This will enable you to locate the secondary radio module in a different location. Please visit the CSL Installer Shop for more information.

This document covers the requirements of a Fire installation and is a supplement for the DualCom. New information includes:

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 DualCom Pro 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.

Inputs

• Input 1: used for receiving the Fire Alarm/Restore signal from the CIE.
• Input 2: used for receiving Fault/Restore signal from the CIE.
• Inputs 3, 5, 6, 7 & 8: used for receiving PIN inputs from any other device (i.e. security CIE). These PINs take a lower priority than 1 & 2 when signalling.
• Input 4: used to indicate if the site is open/closed.

The alarm codes generated by these inputs are as follows:

SIA

Pin 1: UA8001/UR8001
Pin 2: UA8002/UR8002

Alarms

Pins 1 and 2 are dedicated for use with fire panels and will respond to different
conditions, these are:

• Alarm and restore
• Open circuit and open circuit restore (tamper)
• Short circuit and short circuit restore (tamper)

The type of alarm message that is sent will depend on what happens across the PIN(s). Below are the different conditions and messages the Dualcom Fire Pro will generate:

When 14k7 is seen on PIN 1 & PIN 2 it will show a non-alarm state, when this changes to 10k it will go into an alarm state. If the circuit is broken it will generate an open circuit tamper alarm. If it sees an 0v closed circuit, it will generate a short circuit tamper alarm.

PINs 1 & 2 come as normally open going closed out of the box. If you require the input to be set as 10K in non-alarm and 14K7 in alarm, follow the inverting process below.

Inverting

To invert, when the PIN is in an alarmed state, hold the C button until L is displayed.
This should be done outside of the menus.

The wiring configurations are as follows:

Fault Reporting

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 Global Platform 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 Global Platform.

Fault Relay

1. The power is removed.
2. There is a short circuit in any of the interconnections between the CIE and the device.
3. There is an open circuit in any of the interconnections between the CIE and the device.
4. An acknowledgement has not been received from the Gemini Global Platform within the allotted time after a Fire Alarm has been sent (within 100 seconds for Type 1).
5. There are no transmission paths available. Please note, that all available paths must fail before a fault warning is given.

A Fire Alarm will not be restored until all faults (on the 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

Fault Output

On the DualCom Pro Fire, outputs 1a and 1b are volt-free, normally closed going
open when the following conditions are seen:

• Open circuit across either PIN 1 & PIN 2 (tamper).
• Short circuit across either PIN 1 & PIN 2 (tamper).
• ATS failure (both paths when available).
• Power is lost in the unit.

Wiring configurations (depending on what is required at the fire panel) see below:

Acknowledgement Output

Output 2 (ACK) is an open-collector driver that pulls low when activated. It will activate when an alarm/fire/fault restore signal (PIN 1 & PIN 2) is generated and will pulse low for 5 seconds. Below is the wiring configuration (resistor value dependent on what is required at the fire panel):

After 100 seconds (for Type 1) has expired, as mentioned previously. The acknowledgement relay should be used to indicate the successful receipt of a Gemini Global Platform acknowledgement either at the Fire Alarm Panel or by a separate light emitting indicator, as required by EN54-21 5.3.a
