3.9 Tamper Detection on Terminal Inputs
Terminal inputs can be monitored for four state tampering: open, close, tamper short and
tamper cut. If an input is tampered with, an alarm will be triggered in the AC2000 software. The
alarm is a universal tamper alarm and does not distinguish between the four different states. In
order to monitor inputs for tamper short and tamper cut, a resistor network must be installed on
the input sensor wiring as show in Figure 16 B), and the AC2000 software configured to
monitor the input.

Important
It is imperative that the tamper resistor network is wired as close to the sensor as possible.
3.9.2 Re-assembling the terminal
1. Ensure that there is adequate cable length available to reach the connectors comfortably
for each of the following:
–12VDC
– Cat5e/6 cable for communications
– Output wiring for lock
– Wiring for inputs e.g. door position sensor, lock sense
Important
To maintain the terminal’s IP65 rating, the cable access hole should be adequately sealed before completing the
installation process.
2. Attach the front panel of the terminal via the ribbon connector.
