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.
