Alarm transmitter Airborne DC Dual, AddSecure

Alarm transmitter for alarm transmission where there is a need or requirement for alarm communication via two independent alarm transmission routes.

Dial-up protocols based on tone signalling, such as SIA, Contact-ID, and Robofon, are digitalised before alarm transmission. With 16 inputs and 4 relay outputs, the transmitter covers most needs for reliable alarm transmission. Medium and Large are enclosed, the Medium without battery.
