6. Revisions –what they do
Revision 2 (REV2)
REV2 relies on the Bolt Sensor Microswitch to control whether the jaws relock. This
prevents the jaws from being tampered with and being rotated to the closed position.
An inmate may rotate the jaw/s which will prevent the door being closed until the lock
is unlocked.
As an additional safeguard a Reed Switch (which is not normally visible)
can also be used in conjunction with the Bolt Sensor Microswitch. In this
state both the door must be closed (via the reed switch) and the lock
tongue must be in the strike.
This reed switch is enabled or disabled via the small slide switch marked
“Bypass” under the rubber grommet. Bypass ON means reed not in use.
Control Wiring A - Permanent +12 to 30VDC,
B - Control -VE
E - Permanent -VE
Outputs In REV2 (all versions) the jaw microswitches and faceplate tamper in
series are available to be monitored.
Revision 3 (REV3)
REV3 relies on the Reed Switch only to control whether the jaws relock. As in the
REV2 this prevents the jaws from being tampered, but uses the Reed Switch only.
The Reed Switch is always enabled in REV3, the “Bypass” switch has no function.
Control Wiring A - Permanent +12 to 30VDC,
B - Control -VE
F - Permanent -VE
Outputs In REV3 the Bolt Sensor Microswitch serves as an output. The jaw
microswitches and faceplate tamper is a second output available to be monitored.
The maximum door gap between the magnet and reed switch is 8mm.
7. New Model (December 2016) Beyond Serial number 300000 Notes
This new model has some minor enhancements over the existing REV2 settings:
1. Ability to use either or both Bolt Sensor Microswitch and Reed Switch to prevent
the jaws being relocked. Apply permanent negative power to:
Terminal E for Bolt Sensor Microswitch to
operate
Terminal F for Reed Switch to operate
Terminal E and F for both to operate.
2. Slide switch to enable/disable piezo sounder
