5.6.2 Battery maintenance
Battery maintenance requires specialized test equipment. Contact Simplex Service for information on testing batteries.
5.7 Wiring 24V Aux power
24V auxiliary power is wired from either resettable, or on steady terminals. The combined rating for any combination of steady or
resettable devices must not exceed 750 mA.
See Battery Selection Calculations for ULC maximum current draw.
This section provides information on wiring steady 24 VDC power. Resettable 24 VDC power is typically used with four wire smoke
detectors. Refer to Wiring Initiating Device Circuits for specific information on wiring resettable 24 VDC power.
5.7.1 Wiring steady, 24 VDC Aux power
Use the + terminal (24 VDC) and the – terminal (0 V) when wiring a device that requires steady 24 VDC power.
