This device provides the functionality to control the output of a PSU by the means of either a Volt Free
contact (N/O or N/C) or a low voltage signal (12Vdc/24Vdc), as shown in the block diagram below:
Typical Applications
•
Access Control Systems where power is required to be removed from the system devices (i.e. door
locks) in the event of a Fire Alarm activation.
Note: For BS7273-4 compliance, it is necessary to use the
device in ‘Voltage trigger’ mode, to provide fail safe operation under open and short circuit conditions.
•
Any system that requires remote control of a Power Supply output (turn on or off) in response to real
time events.
