Providing a direct and reliable mains source of power to fire alarm ancillary devices, power supply units are essential for a wide range of devices. PSUs are often needed for beam detectors, AOV systems, aspirating smoke detectors, sounder systems and auto-dial communicators, as well as magnetic fire door holders.

These are required because of the voltages needed to operate means they cannot be power via the fire alarm system like other, smaller devices. However, many power supply units feature a backup battery facility which means that the devices can continue to protect your premises even during a power cut. Plus, they don’t prevent communication to the fire alarm system, whether they trigger the alarm or perform a function when activated.

Also, take a look at our range of fire alarm batteries. These are suitable power supply units, as well as fire alarm systems and emergency lighting.
