ZP755B-2 Addressable Sensor Base Sounder 

3374-01

 

Brief description 

Description 

The ZP755B-2 is an addressable sensor base sounder, 

designed for use on Ziton analogue addressable fire 
detection and alarm systems. Conforming to EN54 Part 
3, the ZP755B-2 is developed for applications in 
individual rooms, sleeping accommodation or small 
compartments where it is impractical for the sounder and 

sensor to be separate. 

Application 

Installed directly onto the wiring loop - the ZP755B-2 
enables the system designer to offer a complete 
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. 

The ZP755B-2 features the wide sound distribution 
design, with an 'all around' sound output of 70 dBA. The 
units high efficiency acoustic design and sound 
transducer, enables up to 60 Addressable Sensor Base 

Sounders to be connected to a one-kilometre loop of 1.5 
mm

2

 cable. A plug-in base accepts all loop and screen 

connections, prior to the base sounder connection. A 
volume control is included for areas where a reduced 
sound output is required, but this control must be fully 

clockwise to conform to EN54 Part 3 sound output levels. 

The ZP755B-2 range features a unique self test facility - 
automatically activated during routine sounder testing. 
A built in microphone circuit measures sound output 
level and automatically signals the sounder address 
and location to the control panel, should volume fall 

below the expected test level. 

In systems where loop lengths or current requirements 

are excessive, ZP755B-2 sounders can be powered 

directly from an external power supply. All ZP755B-2 
sounders incorporate switch settings enabling them to 

be assigned a unique address, which is polled by the 
panel every two seconds. 

Continuous, intermittent and two-tone outputs are 

available, from which any combination can be chosen 

to provide alert and evacuate, two stage alarms. All 
sound types comply with BS 5839 Part 1:1988 

recommended frequencies (in accordance with EN54 

Part 3). 

Moulded in high impact thermoplastic, the sounder is 
available in white.
