REM Behaviour

The CL4510 and CL5510 include two connectors called REM ports. The standard behaviour of these ports allows reception desk remote opening (REM 1) and alarm panel trigger opening (REM 2). 

These ports have four different modes of operation you can choose from:

1) Remote Release - In this mode REM1 is used for standard push-button release. REM2 is intended to be used when the lock needs to be released for a longer period.  When a switch or relay connected to REM2 is closed, the lock will open for a period of 30 minutes, after which the lock will revert back to normal operation.

2) Sensor Mode - This mode allows two dry contact switches or sensors (door status and latch monitoring) to be connected.  Trigger entry will also be added to the audit trail.

3) Sensor and Alert - This is a hybrid mode combining the support for a single dry contact switch or sensor (as per sensor mode) and an output.  The output can be connected to any compatible device, such as CCTV, with an input that supports the detection of a falling (changing) voltage.

4) Unlock and Lock Down - This mode supports the connection of two dry contact switches. Connected to REM1, the switch will unlock the lock for the period set by the standard re-lock delay.  Connected to REM2, the switch will trigger lock-down mode (Only the Master and Sub-Master Code will be able to gain access).

If you have changed your mode, remember to synchronise your application.


Turn on this feature to mute the lock.  Please note that when this feature is turned on the lock will flash yellow when buttons are pressed.

Note: Synchronise your application to implement the change.
