Installation Instructions

This section describes the installation of the Model SS4-AS/-AS2 Detector for the
Stand-Alone relay mode. It is recommended that junction boxes be used to wire
the Detectors. Determine the configuration settings for the device(s) and the
number of connections to be used (Fire, Fire Verify, Fault, and Power) depending
on the desired Detection Range and the Fire Control Panel type used (refer to
the Fire Control Panel Manual for details).

Installation Precautions

The following precautions should be observed during installation of Model SS4-
AS/-AS2 Detectors.
1. Make sure that the external electrical power is turned
connecting the Model SS4-AS/-AS2 Detector.
2. Printed circuit board components of the Detector are susceptible to
damage from electrostatic discharge. Do not handle the Detector's
module (and its printed circuit boards) without adequate grounding
and observing all necessary measures to prevent the effect of
electrostatic discharge (ESD).

Conduit Installation

When planning the conduit, follow these recommendations.
1. If only one of the two 3/4 inch NPT conduit openings on the
Model SS4-AS/-AS2 Detector enclosure is used, seal the unused
opening with a threaded plug and approved sealing material.
2. In areas where moisture may accumulate, install an approved conduit
trap or drain.
3. A seal should be installed 6 inches from the enclosure wall for all
applications requiring a Class I, Div. 1 Explosion-Proof rating.

Wiring Recommendations

To prevent intermittent connections, Honeywell Analytics recommends using
junction boxes. Install a junction box near each Detector location. Wire each
Detector to its junction box. Use screw-down terminal strips inside the junction
box to make the connections from the Detector's terminals to an FM Approved or
UL listed Fire Alarm Panel. Also use FM/UL Approved junction boxes and
terminal strips.
NOTE: Avoid wire splices. However, if wire splices are necessary,
all splices should be soldered. Utilization of good wiring practices will simplify
installation, improve reliability, and facilitate maintenance.
