3.8 General Alarm Inputs
The AIM-4SL provides one general alarm input. The wiring to the input should be made with twisted pair 24
AWG wire. If these input is not used, it should be ‘jumpered’ using a 1” (25 mm) long piece of wire
connecting the two terminals to form a closed circuit. This will prevent an alarm condition being reported to
the host.
3.8.1 Cabinet Tamper
This is a normally closed input and should have a jumper installed if not used!
Cabinet Tamper Input: TB19
This input is for connection to a switch located on the cabinet in which the AIM-4SL is installed to detect
unauthorized access to the panel. This is a normally-closed contact. In the event of a tamper condition, the
exit push buttons will not function on all 4 reader connections. This condition will last until one minute after
the tamper has ended. This feature restricts the ability to have easy control of all the doors by merely
shorting the EPB input.
