Transmission protocols

•  SIA P2 (3/1 Pulse Format)

All formats consist of short, predefined messages. Most contain 
several parameters, some of which are optional. Check with your 
dialer receiver and central monitoring station software provider 
for the exact structure they require. 
When programming transmissions, remember that device 
messages require two separate send commands, one for 
activation, and one for restoration.

optional parameters, including time, date, user, partition, and 
device. The format is: 
[Date] [Time] [UserID] AlarmCode [Device | User | Partition]
