Heat Detectors
The Analogue Addressable Heat Detector is
bayonet-fitted to a radio address/transmitter
module incorporating alkaline batteries and
supplied with a surface mount base unit. Removal
of the detector or address/transmitter module will
indicate a fault condition. The detector is
manufactured by Ziton and is designed to comply
with BS5839 Part 5 and EN54 Part 5 (grade 1 and 2) and
part 8 (range 1).
The Heat Detector operates on a highly sensitive
thermistor, which measure the actual temperature
and rate of rise change. At regular intervals, the
detector carries out a self test that checks and
verifies every function, including the thermistor, and
sensitivity to temperature. Any failure is
automatically reported to the control panel.
The detector incorporates a selectable automatic
lock, which if enabled locks it into its base when
plugged in, preventing unauthorised removal.
Each unit has a unique address configured during
manufacture and is individually addressable by the
system controller. The radio address module is
programmed to report at regular intervals of 5 - 9
minutes.
Designed and manufactured using the latest
techniques and surface mount technology ensures
component count is kept to a minimum, thereby
maximising reliability. The address/transmitter
module is powered by a low-voltage dual supply
alkaline battery pack. The battery pack condition
is continually monitored. The battery pack has
been tested to provide a typical 5 years life cycle
for normal site operations. The system indicates
remaining battery capacity and a low battery
condition is indicated to the controller as a fault
allowing 30 days for the battery pack to be
changed before unit failure.

Optical Smoke Detectors
The Analogue Addressable Optical Smoke
Detector is bayonet-fitted to a radio address/
transmitter module incorporating alkaline batteries
and supplied with a surface mount base unit.
Removal of the detector or address/ transmitter
module will indicate a fault condition. The
detector is manufactured by Ziton and is designed
to comply with BS5839 Part 5 and EN54 Part 7.
The Optical Smoke Detector operates on an
advanced light scattering principle, using a wide
angle, light beam together with an extra high
sensitivity photodiode receiver. An internal polling
system checks for smoke particles every 5
seconds. Initial detection of smoke traces
accelerates polling to every 2 seconds The alarm
is verified twice to ensure freedom from false
alarms.
The detector incorporates a selectable automatic
lock, which if enabled, locks it into its base when
plugged in, preventing unauthorised removal.
Each unit has a unique address configured
during manufacture and is individually
addressable by the system controller. The radio
address module is programmed to report at
regular intervals of 5-9 minutes.

thereby maximising reliability.

Radio transmitters are incorporated into each field device to communicate with the controllers. The units are programmed with a device number, zone
number, system code, RX number and TX number. These identities are sent back to the controller in the event of a fire, battery low condition or tamper, to
precisely identify the location of the event on the controller display.
Power to the radio transmitter is supplied by a two stage Lithium battery pack . The battery pack provides up to five years service under normal operating
conditions. When primary power begins to deteriorate, a signal is sent to the controller and a low battery fault is indicated. After a ‘battery low’ signal has
been reported, devices will continue to operate for a further 30 days.
