Switchpac fire protection signaling
ZSP series according EN 54-4/A2
The power supply ZSP135-DR is dedicated to work in systems of fire protection signaling and automation. It is a source of guaranteed 24V voltage. It is manufactured as a wall box with a lock. It has a space inside to mount two batteries. The controller protects the internal battery bank against too low discharge by means of the built-in disconnect device.
