Mains power should be sourced directly from a separate circuit breaker in the
building electrical supply distribution board. This circuit should be clearly marked,
have a bipolar disconnect device, and only be used for fire detection equipment.
Feed all mains cables through the appropriate cable knockouts and connect
them to the fuse terminal block as shown in Figure 8 below.
Keep mains cables separate from other cabling to avoid potential short circuits
and interference. Always secure mains cables to the cabinet to prevent
movement.
