INSTALLATION
8.1
Before installing
These combination smoke/heat detectors must be installed in compliance with the manuals of the Control Panel
NFU-7000 series.
The installation must meet the requirements of the Authority Having Jurisdiction (AHJ).
The combination detectors offer maximum performance when installed in compliance with the National Fire Protection
Association (NFPA); see NFPA 72.
Note:
NITTAN COMPANY, LIMITED is not responsible for the product which is improperly installed, maintained
and tested.
8.1.1
Location requirement
When installing the detector please consider the following items. Otherwise the detector might not provide optimum
performance.
-
Indoor use only.
-
Place the detector away from a ventilation fan or the air outlet of air conditioner, at least 1.5 m (5 ft.).
-
On the ceiling, place the detector at least 10 cm (4 in.) from the wall.
-
On the wall, place the detector between 10 to 30 cm (4 to 12 in.) below the ceiling.
The detector should not be installed in places such as:
-
Place with plenty of air flow (close to a ventilation fan, air conditioner, or place with drafts)
-
Place close to heating appliance
-
Place with a constantly high temperature or humidity
-
Place with lots of dust or insects
-
Place where vapor can directly come in
-
Place with exhaust gas such as garage
8.2
Heat detector applications
Heat detectors sense change in air temperature and initiate an alarm condition based on a fixed-temperature point, rate
of temperature rise, or amount of temperature rise above ambient condition. Spot type heat detectors should be
selected so that the rating is at least 11 °C (20 °F) above maximum expected ceiling temperature. Ceiling height,
construction, and ventilation play significant roles in detector performance and must be considered when determining
detector placement. The operating temperature range is 0 °C to 37.8 °C (32 °F to 100 °F).
