Duet2 D2600 / Duet3 D2650 Installation Manual – EU-D2600-D2650-INST/A10/v1 - 6
4. Installation
1. Site the aerial at the point of strongest signal ensuring that it is within the protected area.
This is usually the highest point in the building and well away from metal roofs and metal
walls (use Dycon D2366 Test Set). See Page 13.
2. Program the NVM for the system specific requirements using the D2454 Programmer
software. See page 18.
3. Obtain a GPRS-enabled SIM card from your GSM Service Provider.
4. Totally power down the control panel mains and battery.
5. Fit the GPRS enabled SIM Card in the socket on the Duet.
6. Where required, fit the D2355 LAN card and connect to the LAN using a CAT5 cable.
7. Fit the NVM into the 8-pin socket located at the front of the Duet. See Fig 1.
8. Connect the 4 inputs and 4 outputs as required. See Fig 1 and Page 17.
9. Connect to the FLT relay terminals as required. See Page 12.
10. Connect the aerial to the Duet aerial connector. See Fig 1.
11. Connect the control panel’s PSTN line to the A2, B2 terminals. See Fig 3.
12. Connect the user’s PSTN telephone system to screw terminals A1 and B1 provided under
the protective cover. (For security installations, only ‘serial connection’ is recommended
for other equipment that is using the same PSTN line). See Pages 17 to 23.
13. Connect the PSTN line to the A, B screw terminals. See Fig 3.
14. On the Duet, connect the ‘12v +’ & ‘12v -’ terminals to the control panel or power supply’s
12 volt output (often called ‘Aux supply’ or ‘DC power’). See Fig 1.
15. Note the SIM Card number, NVM ‘chip’ number (and any security access numbers) on the
site records that will be stored at your office.
16. Reconnect the mains supply to the control panel. The Duet is now ready for testing.
5. System Testing
Ensure you have informed your Alarm Receiving Centre that you are ready to test your Duet.
1. Power up the Duet, the unit will initialise. This will take 40 seconds. Refer to Appendix 1
for LED indications.
2. To test all programmed reporting paths to the ARC, momentarily short the test pins
on the Duet (see Fig 1). This will cause the Duet to send a test signal to the ARC on each
path used (LAN / GPRS / GSM / SMS).
Once the test pins are shorted, communication LEDs will illuminate to indicate call
progress on each path (Green for LAN and Yellow for GPRS / GSM). During
communication the LEDs will flash to indicate the progress of the call, see Appendix 1.
The Alarm Receiving Centre should receive a test call for each path used.
