The right voltage for a reliable fire alarm.

A power supply (PSU) makes sure your fire alarm gets the correct voltage, so it works reliably.

How do I choose a fire alarm power supply?
  • Voltage: match the PSU output to your panel or devices.
  • Current: add up what everything on the supply draws, then pick a PSU rated above that total.
  • Standby battery: size it to the load, so the system keeps running in a power cut.
  • Panels and devices: see the full fire alarm range.
