INPUTS
The A22 can monitor the state of up to 6 devices (12 using zone doubling) such as magnetic contacts, motion
detectors, temperature sensors, or other devices. The following are examples of the type of inputs that can be
monitored:
Magnetic Door Contact:
Permits supervision of door “status” (opened, closed, opened too long, forced open). Inputs “Door
Contact 1” and “Door Contact 2” are assigned by default as the door contact for Door 1 and Door 2
respectively. When using the default system settings, you can easily swap terminals to troubleshoot
the installation.
Request to Exit (REX):
The device used can be a push button, vertical-view motion detector or oor mat sensor. The door can
then be programmed to unlock on a REX detection. When a magnetic door contact is installed, the
system can dierentiate between a door forced open and an authorized exit. Inputs “REX 1” and “REX
2” are assigned by default for Door 1 and Door 2 REX inputs respectively.
