WIRING
A maximum of two 1.5mm
be connected at any one terminal. All
wiring terminates at the base as follows:
R: – Remote*
L: – In and Out
L1: + In & Remote
L2: + Out
* When a common remote indicator is
used for two or more detectors, join the 'R'
terminal to the next base 'R' terminal. The
remote indicator will then activate when
any of the connected detectors signals an
alarm.
SEALING DETECTOR BASE HOLES
Where differential air pressure may exist between a ceiling cavity and the room below, it is advisable to seal cable access holes
to the back of a fire detector in the room, thus stopping ceiling cavity air from flowing past or through the detector that could
otherwise affect reliable fire detection. Such air flows may cause more rapid dust or moisture build-up in the detector or "shield"
the detector from smoke or hot gas in the room during a fire.
AVOIDING NUISANCE ALARMS
The incidence of nuisance alarms can be greatly reduced if the following precautions are taken:
a. Do not install smoke detectors in environments contaminated by airborne particles (eg. dust, saw-dust), where cigarette
smoke is prevalent, or in areas with condensing humidity (eg. bathrooms). Use appropriate heat or carbon monoxide detectors
in these areas.
b. Do not install detectors where high air velocity is expected. Air flow will increase the amount of dust that accumulates in a
detector and will increase the risk of nuisance alarms.
CARBON MONOXIDE FIRE DETECTION
CO is a toxic gas produced by carbon-based fires. Being colourless, odourless and tasteless, CO is almost impossible for
a person to detect. Exposure to raised levels of CO can cause disorientation and collapse during physical exertion, whilst
exposure to high levels of CO can lead to permanent brain damage and death. Slow-developing and smouldering fires produce
significant quantities of CO before detectable levels of smoke are released. In these situations CO detectors actuate far earlier
than Photoelectric or Ionisation smoke detectors. Where the 614CH is used in sole occupancy units, it must be installed on
heat detector spacing.
DETECTOR SELECTION GUIDE
In the table below, detectors in BOLD are recommended as the most suitable for detecting the given type of fire in the
particular environment. Non-bold detectors are suitable but may not give optimum performance for that application.
Environment
Fire type
Overheating (electrical/
electronic equipment)
Smouldering
(wood, paper)
Flaming
(wood, paper, flammable liquids)
Flaming with high heat
(late stage flaming)
614I = Ionisation Smoke Detector 614P = Photoelectric Smoke Detector 614CH = combined Carbon Monoxide (CO) and Class A1R Heat Detector
614T = 614T Heat Detector. These detectors can be used separately, or combined, to provide fire detection for most applications.
