Compact safety power supply (SPS) for fire alarm systems

Fire detection systems

The SPS range of EN54-4 certified safety power supplies offer a compact, robust and versatile power solution to installers, allowing them to safely power fire detection and signalling systems in small to large installations.

The compact and discrete design provides added flexibility for the power supplies to be installed in public places. Comprehensive yet simple LED status indicators on the front of the unit help installers, commissioners and maintainers assess the status of the unit.

Overview Models Resources Support

Efficient

Reduces number of power supplies needed

Flexible

For two-wire, conventional, addressable fire systems

Discrete

Compact enough to install in public places

Less is more with SPS

Half the size of its predecessor, the SPS range's compact size makes it simple to work with and straightforward to install. Saving valuable space in buildings, its small form factor enables its use in public areas.

Smaller box, better performance

Don't let its size fool you, it may be small but the SPS doesn't compromise on power. Its high usable current output reduces the number of power supplies required for powering devices such as EN54-23 VADs, signboards and door retainers. Lessening the cost and space taken up by power supplies.
