MBS - Magnetic Bond Sensor: Sends a signal the lock and armature are properly engaged.
DSM - Door Status Monitor: Sends a signal when the door is open.
RTD - Relocking Time Delay: A separate unit spliced into the wiring that controls unlock time.
It is furnished standard with the Locknetics GF3000.
The DSM and MBS options are additional switches that send a signal back to a remote
monitoring station. These stations are found in high security applications and are
typically a separate room used to monitor door status.
The remote station contains a series of panels and lights.
Each door will have several lights that change color as the door opens.
The DSM and MBS switches are wired to these lights.
