Honeywell Power Products announces a new 12-Amp fire alarm power supply, designed for large-system installers. The HPFF12 is Honeywell's largest fire power supply, capable of powering a fire alarm's four NACs (notification appliance circuits) to full capacity. This powerful, yet compact unit is ideal for installations using higher-power strobes or facing limited wall space for multiple supplies. For even larger installations, the HPFF12CM (chassis mount) version holds up to three HPFF12 supplies with two 12AH batteries per supply in one compact, lockable enclosure. The unit shares the same fast installation and maintenance features as Honeywell's HPFF8 eight-amp fire alarm power supply. Independent output circuit supervision enables both to notify an attached control panel of a NAC fault in addition to displaying past NAC troubles stored by its convenient trouble memory feature.
