Power Supplies & Batteries

Power Supplies

Bring your power supply needs up to date with the Premier Power Pack Power Supply. The in-built LCD screen displays your power supply parameters and conditions for quick and easy status updates.

Information you can access on-screen includes output voltage, output current, charge type and battery state.

This unit itself uses a three-state charger, using Boost, Float or Pulse modes depending on the current state of the battery.

Under mains fail conditions the PSU will disconnect the batteries when they are fully discharged to prevent battery damage. The PSU will also signal a fault if it detects high internal resistance within the battery.

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 2.2Ah, 7Ah, 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).
