Pulsar fuse module for EN54C/EN54M power supplies, 4x0.5A

Pulsar EN54C-LB4 divides the output of a fire alarm power supply into four separately protected outputs. Input IN1 feeds AUX1 and AUX2, input IN2 feeds AUX3 and AUX4, and each output is protected by an F 0.5 A fuse (1 A fuses can be fitted).

When a fuse blows, the LED of that output goes out and the power supply's relay fault output reports it, so the fault reaches the control panel.
