INTRODUCTION TO THE PREMIER POWER PACK PSU
The Premier Power Pack is an EN54 compliant Power Supply, intended to power ancillary fire alarm equipment.
It incorporates a small LCD screen that will give information about the Power Supply status (such as output
voltage, output current, charger voltage etc).
It also displays basic information via its LEDs (Power/General fault / earth fault & Battery fault). These LEDs are
located on the panel door, and also on the controller PCB itself.
The power supply has a 3 state charger. It will initially supply a BOOST charge current, until it has detected that
the battery is close to full charge, then it will switch to FLOAT charging. If it detects flat or missing batteries, it will
switch to PULSE mode, until it detects good batteries.
The PSU monitors batteries for High Internal resistance, and will report a fault if it detects a resistance that would
prevent the PSU giving its rated output.
The power supply will prevent battery deep discharge by disconnecting the batteries when they reach their final
voltage under a mains fail condition.
The Power pack PSU is also available as a “CIE version”, used to power fire alarm panels. This version of the PSU is
normally supplied without the current measuring feature.
The “Control panel” version does not have the LCD fitted, so will communicate its status via its internal LEDs only.
