Laser Safety Systems description of a defeatable access controller with electric strike input

The LSS-2386B Defeatable Access Monitor is designed to receive the voltage pulse produced by any low voltage access control system (12 to 24 volts, AC or DC). When the pulse is received, the system will immediatly override the door interlock and ignore the door position switch for a specified time period. The input pulse is optically isolated, so the laser interlock system has no electrical connection to the existing access controller. The existing access control system can be a card reader, proximity reader, biometric reader, or traditional keypad.

If using this system, the facility must ensure that only laser trained individuals are permitted to use the electronic entry during laser operations.

The behavior of this system is almost identical to the LSS-2386 system with electronic mortise latch, except it does not have the electronic latch or hand proximity detector for automatic override. We provide a traditional "Push-to-Exit" button to initiate the override upon exit. The client may install a motion detector in lieu of this button if desired to automatically initiate an exit override.

We have a client at a large research facility that needed to interlock a laser lab conducting highly classified research. The entry to the laboratory requires the use of a secure card reader system that releases an electric strike. The client liked our model LSS-2386 Defeatable Access Control Kit with electronic mortise latch, but told us that the new latch would not meet their high security protocol. The client asked if there was a way to interface their existing card reader directly to our LSS-2386 module. This request inspired the development of the LSS-2386B module shown below.
