SECTION 2: INSTALLATION
2.1
Installation Procedure
This section describes the installation of the Model SS4-AI Detector for the
Stand-Alone mode. It is recommended that junction boxes be used to wire
the Model SS4-AI Detectors. Determine a mounting location for the
detector which is within the detectors range (see Detection Range and
Field-of-View) and has a clear view of the fire threat area. Where multiple
detectors are used to cover a large area, the detectors should be located to
allow overlapping Field-of-Views. Determine the configuration settings for
the device and the number of connections to be used. (Fire, Fire Verify,
Fault, and Power) The configuration settings and number of connections
will depend on the Detection Range desired and the type of Fire Control
Panel used. For Configuration information see the Dip Switching Setting
chart and the manual for your Fire Control Panel.
2.1.1
Installation Precautions
The following precautions should be observed during installation of Model
SS4-AI Detectors.
1.
Double-check to make sure that the external electrical power is
turned
OFF
before connecting to the Model SS4-AI Detector
.
2. Do not handle the Model SS4-AI Detector's module (with its
printed circuit boards) without being adequately grounded.
Printed circuit board components are susceptible to damage from
electrostatic discharge. Grounding may be accomplished by
wearing an anti-static wrist strap connected to an earth ground.
2.1.2
Conduit Installation
Model SS4-AI Detectors should be located to cover the specific "fire threat"
areas.
When planning the conduit, observe the following recommendations.
1.
If only one of the two ½ inch NPT conduit openings on the Model
SS4-AI Detector enclosure is used, seal the unused opening with a
threaded plug.
2.
In areas where moisture may accumulate, install an approved
conduit trap or drain.
3.
A seal shall be installed within 6 inches of the enclosure for
applications requiring a Class I, Div. 1 Explosion-Proof rating.
