Power Supply Units

Fire alarm power supply units are necessary for ancillary fire alarm systems. Business and public premises are required to have fire alarm systems in place, in line with the Fire Safety Order 2005. Due to their high voltage, they need to be powered by the mains. This is where the power supply unit (PSU) comes in. 

Most power supply units also have a battery backup. This ensures the fire alarm system is still fully functional in the case of a power outage.

We have a wide range of fire alarm power supply units to ensure your system runs reliably and with little maintenance. Whether you need a full 24-volt main supply unit, door release supply unit or fire alarm panel mains isolator, we've got you covered.
