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.
