AJAX MultiTransmitter User Manual page 8

MultiTransmitter has 18 wired zones. The number of connected devices depends
on their power consumption. The total maximum current consumption of all
connected devices or detectors is 1 A.

The integration module has 3 power supply lines of 12 V: one dedicated line for fire
detectors and two — for other devices.
After the fire alarm, fire detectors need a power reset to restore normal operation. Therefore,
the fire detectors power supply should only be connected to a dedicated line. Also, avoid
connecting other detectors and devices to power terminals of fire detectors as this may lead
to false alarms or incorrect operation of the devices.
Event transmission to the monitoring station
Ajax security system can connect to the CMS and transmit alarms to the
monitoring station in Sur-Gard (ContactID) and SIA protocol formats.
The loop (zone) number of the integration module and the devices connected to it
can be found in Ajax apps, in the Groups menu of the hub settings.
To learn the loop (zone) number, select the group in which the integration module
is located or the desired connected device. The Device Number (or DeviceIndex in
Ajax PRO Desktop ) corresponds to the loop (zone) number.
