How to test the Bark Armed Strike Plate on different lock types

 Mortise Sash Lock

A mortice sash lock has a latch bolt that is connected to the door handle movement and a deadbolt that is moved in position by turning the lock key. When locking the door the deadbolt will move next to the pressure sensor into the Armed Strike Plate.

How to test the Armed Strike Plate for a mortice sash lock installation:

• Make sure the door has been locked and connected to an alarm.

• Push down on the door handle (to open the door) and place your weight onto the door (do not shoulder the door) – the alarm should not activate.

• Keep pushing down on the door handle and shoulder the door with more force (the force will depend on the intensity and weight of the person – see test results below). If you place more than ±40 kgf (±392 N) the alarm will activate.

• Should the door handle not be pushed down, you will require more force to activate the alarm. This can relate to damaging the latch bolt of the door lock.

• After each pressure test the pressure sensor will move back in position and will be armed again.

Cylindrical Locks

A typical cylindrical lock has only a deadbolt or a lockable latch bolt that will lock into the Armed Strike Plate.

How to test the Armed Strike Plate for a cylindrical lock installation:

• Make sure the door has been locked and connected to an alarm.

• Place your weight onto the door (do not shoulder the door) – the alarm should not activate.

• Shoulder the door with more force (the force will depend on the intensity and weight of the person – see test results below). If you place more than ±40 kgf (±392 N) the alarm will activate.

• After each pressure test the pressure sensor will move back in position and will be armed again.

How does it work?

When forces are used to open the door, typically by an intruder that does not have the key to the door, the deadbolt will push onto the pressure sensor. The special springs inside the pressure sensor will give way, which in turn push on the micro switch that will trigger the alarm.
