• Tie the wiring located between bays to the internal wiring troughs, if applicable.
• When powering remote units or switching power through relay contacts, power for these circuits must be provided by a power-limited
power supply listed for fire-protective signaling use. An EOL relay must be used to supervise the auxiliary power circuit.
• Auxiliary power only: Supervision must be provided if the auxiliary power circuit is to be wired as a power-limited circuit. In order to
connect a circuit using power-limited wiring, the devices being powered must all be addressable, or a UL Listed EOL relay must be
used to supervise the circuit. Refer to Figure 28 for wiring directions for the EOL relay.
