Heat
These detectors use two networked thermistors in
a bridge configuration to provide a fast response,
that depends both on absolute
temperature and notes the
change of temperature. The rate
of rise/fixed temperature heat
detectors can be used in areas
where smoke sensors are
unsuitable due to environmental
conditions (smoke, dust etc,).
Such areas include kitchens,
locker rooms, canteens,
garages, loading bays etc.
The integral electronics emulate
conventional fire detector's response curves and
transmit the state to a controller as an alarm
condition.

Ion Chamber Smoke
These detectors react to the visible
and invisible fire aerosols
(products of combustion) and are
therefore capable of detecting the
early presence of hot smouldering
and flaming fires, such as wood,
paper etc.
They are particularly suitable for general
applications in all areas and use a dual ionisation
chamber in which the air is ionised by a single
radioactive source (33k Bq Americium 241). The
presence of smoke in the sampling chamber
causes a change in the balance voltage, between
the two chambers. This is then compared against
an alarm level.
