The ZP755R is an addressable, sounder, designed for use on ZP3 and ZP2 analogue addressable fire detection and alarm systems. Developed for applications in individual rooms, sleeping accommodation or small compartments where it is impractical or unnecessary for the sounder and sensor to be combined. Installed directly onto the ZP wiring loop - the ZP755R enables the system designer to offer a complete ZP3 analogue addressable system on a single pair of wires. Installation costs are greatly reduced, whilst system integrity, sounder options and programmed alarm organisation are significantly increased. Time on site is further reduced as the moulding plugs directly into a first fix base - eliminating the need for any internal connections.
