We received this question via email:
I would like to connect two devices to the Dialer:
Input One : Burglar Alarm
Input Two: Smoke Alarm
I have an Citadel Xr2 alarm system which I assume is pretty standard to get a signal from it [it is!].
The smoke detectors are from the Aico range, and would be interfaced through a Relay base Ei128RBU.
Wiring the Citadel Alarm and Aico Smoke alarms to the Advent Controls GSM Alarm Auto-dialer and SMS Sender is very straight forward and the default input settings can be used. The 0v terminal on the alarm panel and the GND terminal on the dialer must be connected together. The bell -ve terminal is also connected to the selected input on the dialer.
The Aico Alarm has a set of relay output contacts which can be connected directly to Input B (in general ensure they are Volt-free and do not supply mains voltages!!). Use the COM and NO terminals on the alarm as shown in the diagram.
For a basic setup you will need to send these messages:
master <your mobile number>. (this sets your phone up as an administrator – remove red jumper afterwards)
callnum <1st number to be rung>.
callnum <2nd number to be rung>. (you can keep doing this!)
textnum <text recipient>.
textnum <another SMS recipient>. (again there is space for over 250 numbers)
If you would like the messages to say something specific you can send (for example):
customa the burglar alarm is sounding.
customb the fire alarm is sounding.
If you would like to know when the alarms have stopped sounding send these commands:
customah the burglar alarm has stopped sounding.
custombh the fire alarm has stopped sounding.
