Key Features

  • 2A or 4A true-load
  • Two monitored, fused outputs
  • Attractive, metal-clad, powder coated enclosure
  • Hinged, lockable door with integral LCD status display and controls
  • 3-state charging circuit; boost, float and pulse mode


The ProFyre range of power supplies employ state-of-the-art switch mode power technology to provide a continuous and reliable source of 24V dc power to meet the technical and legislative requirements of the professional fire detection and alarm industry/installer.

There are two metal-clad boxed versions available, 1.5A or 4A ‘true-load’, each having two monitored and fused outputs with internal space for up to 2 x 12Ah or 17Ah batteries respectively. An innovative door mounted LCD display together with 4 LED indicators and two control switches, provides fast and efficient visual status of all critical functions.

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.

Additional Features

  • Earth fault monitored
  • Automatic battery deep-discharge protection
  • Battery internal resistance monitoring


The ProFyre P2 and P5 are fully approved by Intertek for safe use and installation in any European Union country and bears the CE mark to show that it complies with all the applicable Directives including the CPR, EMC and the Low Voltage Directive (LVD).
