3. Keypad Tampering

To prevent tampering, a tamper switch can be installed in the single

gang box used for mounting the keypad. The tamper switch must

activate if the keypad is removed from the box and must disconnect

power from the lock. The lock must be a fail-secure device, meaning

the lock remains locked when power is removed. In addition, once

the tamper device is activated, it must be configured so that it can

only be reset from within the protected area. Only a Sentrol 3012 or

Sentrol 3025T tamper switch can be used. The diagrams on the next

page show the suggested mounting location for each device.

3.1 IEI Tamper Power Supplies

IEI access system power supplies are designed specifically for

access control applications. Two models are available: board level

and in a cabinet. Both feature a tamper circuit with a reset button

mounted on the circuit board. Using the tamper switch as detailed

and connected to the power supply tamper circuit, unauthorized

opening of the case or prying the unit off thewall triggers this tamper

loop, thus preventing the lock from being released until the reset

button is pressed.
