Our DualCom GradeShift range offers a single piece of hardware for every grade of risk with interchangeable EN Grades. You simply pick the grade required and can remotely change the grade at any time if required. GradeShift Fire is EN54 compliant, meeting the requirements for Fire detection and fire alarm systems.
See links and information below for technical support, guides and installation videos.
Yes. The GradeShift UDL supports a secondary path in addition to the primary GSM path. The following Gradeshift UDL variants are available:
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.
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.

Yes, by default the LAN path is set to use DHCP. This means the GradeShift UDL will automatically try to get the network configuration when it is connected.
The LAN path can be changed from DHCP to Static IP if the network on a site requires it. Please note if the LAN path needs changing to static IP, we will require the following details:
This information should be provided by the company that is managing the IT network for that site.
Important Note: This change can only made by our Technical Support team. Please get in touch by calling +44 1895 474 444 or email support@csl-group.com.
Yes, the LAN path can be changed from DHCP to Static IP and vice versa. Please note if the LAN path needs changing to static IP, we will require the following details:

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.
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.

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.

Check, using the LEDs that no LAN path faults exist. (See Appendix 1, Table 21 in full Quick Guide) for fault indications. These will help diagnose LAN path problems.
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.
