Product Description
Description
The ZP755R-2 is an addressable, sounder, designed
for use on Ziton analogue addressable fire detection
and alarm systems. Conforming to EN54 Part 3, the
ZP755R-2 is developed for applications in individual
rooms,
sleeping
accommodation
or
small
compartments.
Application
Installed directly onto the wiring loop - the ZP755R-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 ZP755R-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 room
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 ZP755R-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, ZP755R-2 sounders can
be powered directly from an external power supply.
All ZP755R-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 either red or white.
