3.13 Tamper Detection on Reader 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 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.
3.13.2 Configuring software for tamper detection
1. From the Floatbar select Device Configuration | Devices.
2. Select the device on which inputs are to be configured for four state tamper detection.
3. Select the Configuration tab.
4. Select the Input Config tab.
5. Select each input element to be configured for four state and tick the 4 state checkbox.
6. Click Save.
