3.14 Tamper detection on reader inputs
Terminal inputs can be monitored for 4-state tampering, open, close, tamper short, and tamper
cut. If an input is tampered with, an alarm is triggered in the AC2000 software. The alarm is a
universal tamper alarm and does not distinguish between the four different states. 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.
3.14.2 Configuring software for tamper detection
To configure software for tamper detection, complete the following steps:
1. From the AC2000 Floatbar, click Device Configuration, and click Devices.
2. Select the device on which inputs are to be configured for 4-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 check box.
6. Click Save.
