PERATI N
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 ‘Volta e tri er’ 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.

Trigger & Jumper Configurations
The device has 3 modes of operation set by the onboard jumpers:
•Contact Mode (Normally Open) - Jumper across: 2 & 3
•Contact Mode (Normally Closed) - Jumpers across: 1 & 2 and 3 & 4
•Voltage Mode - Jumper across: 3 & 4
Table 1 defines the output state of the N.O and N.C contacts with respect to Mode selected and Trigger inputs.
Note: Trigger Input terminals + and - are only polarity conscious when used in Voltage mode

Typical Setup:
I NSTALLATI N AND S ET -U P
Note: Ensure all power is removed while connections are made to the device.
1. Ensure PSU voltage matches the PSU Relay Interface rating (12Vdc or 24Vdc).
2. Set jumpers to required Trigger method.
3. Mount PSU Interface Relay using self-adhesive mounting feet supplied.
4. Make required connections.
5. Apply power and test relay operation by using the appropriate Trigger selected.
