5.5.4. The VM652P key-hole protection kit
The key hole protection mounting plate VM652P has a stainless steel lever which in
night position will cover the key hole and thereby stop the intruder from inserting
explosives in the key hole.
At the same time the detector protects the safe or vault door from other kinds of
attack.
The lock/release button must always face up (1).VM652P can be mounted with the
lever facing any direction (2).

Select a location for the VM652P on the vault/safe door.
2.
Mounting holes A are used for the VM652P.
3.
Drill/tap mounting holes as described in chapter 5.2.
4.
Mount the VV600/602Plus detector on the VM652P cover plate and wire the
detector according to the desired system configuration.

The micro-switch inside the VM652P should preferably be wired into the
detector’s alarm loop to inhibit arming the alarm system if the keyhole
protection lever is not in the protected position.
6.
The location of the lever can be changed if necessary. To open the mounting
plate and re-position the lever, the centre screw (B in the illustration) has to be
removed.
