ZP730-2P

Designed for early response to slow burning,
smoldering fires, the ZP730-2P is a POLAR WHITE,
addressable smoke detector developed to provide
reliable sensing for most fire alarm applications. The
detector’s proven stability in air movement
associated with air conditioning systems has made it
a popular selection for modern building interiors.
Operating on light scatter principles, the ZP730-2
fully meets the sensitivity requirements of EN54 Pt 7
and is approved by several international approval
bodies.

False and unwanted alarms are virtually eliminated –
smoke levels are continuously sensed by the unit
and transmitted via the ZP wiring loop as electronic
signals. These are assessed and verified by the
control panel prior to any alarm decision being taken.
Installed as part of a ZP addressable system, up to
127 sensing devices may be connected to each of
the control panel loops. All loop devices incorporate
switch settings enabling them to be assigned a
unique address that is polled by the panel every two
seconds.
Sensor sensitivity, calibration and self-test are
carried out automatically by the ZP system. Removal
or replacement of an incorrect sensing device will be
identified by the system and shown as a fault.
Sophisticated auto contamination adjustment
compensates for any drift in performance due to dirt
in the sensing chamber.

For ease of removal sensors plug into a range of
base units by a simple twist and lock action. A site
selectable option is provided to lock the sensor into
its base. Once applied the unit can only be removed
by means of a special tool.
A red LED indicator situated on the sensor moulding
flashes to indicate when the unit is in alarm. Space
for address labels is provided on sensor and base
mouldings, ensuring units are replaced in their
correct location and address numbers can be
identified from floor level.
