Updated December 29, 2020
MultiTransmitter is an integration module with 18 wired zones for connecting third-
party detectors to the Ajax security system. To protect against dismantling,
MultiTransmitter is equipped with two tampers. It is powered from the mains 100–
240 V AC, and can also run on a 12 V backup battery. It can supply 12 V power to
connected detectors.
MultiTransmitter operates as part of the Ajax security system by connecting via the
secure radio communication protocol to the hub. The hub communication
range is up to 2,000 meters provided there are no obstacles. If jamming or
interference is detected, the “high level of interference at Jeweller frequencies”
event is transmitted to the central monitoring station of the security company and
system users.
