Installation intructions (wiring)
Connecting the bridge to the alarm system is quite simple. Using four wires make the following connections:
- The CLK terminal on the bridge to the YEL terminal on the alarm panel.
- The DATA terminal on the bridge to the GRN terminal on the alarm panel.
- The + terminal on the bridge (P2(1)) to the AUX+ terminal on the alarm panel.
- The – terminal on the bridge (P2(2)) to the AUX- terminal on the alarm panel.
Probably, the terminals on the panel are already in use. Don´t disconnect the connected wires, just add the new ones from the bridge to the terminals.
Because of the low voltage on the terminals, there is no risk of electric shock but while touching the wires, the alarm system could be triggered due the anti-vandalism mechanism. If this happen just disarm the system by entering the code on any keyboard.
If your alarm system is being monitored, be prepared to receive a contact from your monitoring service provider, in case alarm system is triggered. Other option is to put the monitoring service provider in aware of the installation beforehand, to make him dismiss the event.
Powering the device from an external source
The device should be powered from the alarm system and not from a different source. However, if opting to power the board externally, it is imperative to ensure that the ground connections are aligned to prevent any potential damage to any of the devices. When utilizing an external power source, employ a DC12V and ensure both the external source and alarm system GNDs are connected together, as depicted in the following image.
