Premier Power Pack EN54-4 Power Supply with LCD Screen
The Premier Power Pack Power supply uses an innovative design that allows the engineer to view system status through the on board LCD screen. The screen can display several power supply parameters, including output voltage, and output current.
The power supply itself uses a 3 state charger which uses BOOST, FLOAT, and PULSE modes, depending on the state of the battery.
The PSU will disconnect the batteries under mains fail condition, when the batteries are fully discharged to prevent damage to the batteries.
The PSU will also monitor the battery for high internal resistance, and signal a fault if that condition is detected.

Batteries
As fire alarm systems are life safety systems, they must have a battery backup in order that they will operate in the event of a mains failure. All parts of the system, including auxiliary power supplies must have a battery backup.
All the batteries stocked are 12 Volt batteries, meaning that 2 batteries are required for a 24 volt system. The standard capacities stocked are 3.4Ah, 7.2Ah, 12Ah and 17Ah.
It is important to choose the correct battery size for the system load to give the required standby time (usually 24 or 48 hours).
