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. See Page 10.
2. Program the NVM for the system specific requirements or obtain a pro-
grammed NVM from your Alarm Receiving Centre. See page 32.
3. Ensure that a GSM SIM Card is fitted in the DualCom. See page 12.
4. Totally power down the control panel mains and battery.
5. Fit the NVM into the 8 pin socket located at the front of the DualCom. See
Fig 1 & 2.
6. Where required, fit the CS1050 Expansion board, See page 14.
7. Connect the input triggers to the DualCom. See page 12 and Appendix 2.
8. Connect to the relays “Fault” and “Aux” as required. See page 15.
9. Connect the aerial to the DualCom aerial lead using the threaded connector
provided. See Fig 1.
10.Connect the PSTN line to the terminals provided under the protective cover.
For security installations, only ‘serial connection’ is recommended for other
equipment that is using the same line . See Pages 22 to 30.
11. On the DualCom, connect the ‘12v +’ & ‘12v -’ terminals to the Control Panel
or Power Supply 12 volt output (often called ‘Aux supply’ or ‘DC power’).
See Fig 2 and page 31.
DO NOT supply power to the DualCom directly from the battery be-
cause this may bypass the current limited charging circuits found in
many modern power supplies.
The ‘Start’ ‘+’ & ‘-’ terminals next to the 8 input terminals are to assist
input triggering only. These terminals are not the supply connector.
12.Note the SIM Card number, NVM ‘chip’ number (and any security access
numbers) on the site records that will be stored at your office.
13.Reconnect the mains supply to the control panel. The DualCom is now
ready for testing.
