LC 1200 Manual The LC unit 2-7
Tamper Switch adjustment
The Tamper Switch (S1) (Figure 2.10) is
provided to prevent unauthorized access to the
LC unit. An alarm is generated if the LC unit
cover is removed (i.e., the Tamper Switch clip is
open).
During normal use, the Tamper Switch clip is
held closed with pressure between the contact of
the clip and the outside case (see Figure 2.11).
After initial installation and wiring, replace the
outside cover and enter a Keypad reset. If you
receive a Tamper alarm, it may be necessary to
adjust the Tamper Switch to maintain good
contact with the outside case.
Using needle-nosed pliers, gently bend the
Tamper Switch clip slightly outward (see Figure
2.11). Make only one or two small adjustments,
as repeated bending can cause the metal to
break.
Replace the LC unit cover and enter a Keypad
reset. If a Tamper alarm persists, repeat the
procedure until a good contact is made between
the Tamper Switch clip and the outside case.
