The LNL-FUSE-12FOMx Fire Output Module With
Individual Fused Fire Relay Functionality
The LNL-FUSE-12FOMx Fire Output Module with Individual Fused Fire
Relay provides these features:
• Available with 4, 8 or 12 controllable outputs
• Multiple trigger configurations
• Contact rating: 10A at 12 VDC
• Each output is selectable for switched or permanently on
• LED indication when relay is energized
• Low current consumption
• Standalone device - retrofit into any 12 VDC PSU
Operation
This device provides the functionality to control the output of a PSU by the
means of either a Volt Free contact (NO or NC) or a low voltage signal
(12 VDC or 24 VDC):

Typical Applications
• Any system where power is required to be removed from the system
devices (for example, door locks) in the event of a fire alarm
activation.
Note: For BS7273-4 compliance, you must 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.
Connections
Note: This unit is NOT suitable for switching 240 VAC mains loads.
Trigger and Jumper Configurations
This device has three modes of operation that are set with the on-board
jumpers:
• Contact Mode (Normally Open) - Jumper across pins 2 and 3
• Contact Mode (Normally Closed) - Jumpers across pins 1 and 2, and
pins 3 and 4
• Voltage Mode - Jumper across pins 3 and 4
Trigger Select
Each channel can then be configured using the jumpers next to the relevant
fuse.
Note: To disable the channel (no output), remove the jumper.
