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.
