2.1
Installation Procedure
This section describes the installation of the Model SS3 Detector for the Stand-Alone mode. It is
recommended that junction boxes be used to wire the Model SS3 Detectors..
2.1.1
Installation Precautions
The following precautions should be observed during installation of Model SS3
Detectors.
Double-check to make sure that the external electrical power is turned
2.1.2
Device Layout
Model SS3 Detectors should be located to cover the specific "fire threat" areas. The Model SS3-A and
SS3-AN Multi-Spectrum Detectors' field of view is 120º with a range of 30 feet to an industry-standard
one square foot Type B gasoline pan fire. In area coverage applications the Detectors should be located
with overlapping fields of view to insure complete coverage of the area. Detectors should also be
located away from strong RF (Radio Frequency) sources. The Model SS3-AB and SS3-ABN UV Fire
Detectors are designed for enclosed areas and feature a wide 180º field of view.
2.1.3
Wiring Recommendations
Fire Sentry Corporation recommends using junction boxes to help prevent problems with intermittent
connections. Install a junction box near each Model SS3 Detector location. Next, wire each Model SS3
Detector to its junction box.
connections to the Detector's terminals and a UL/FM Approved Fire Alarm Panel. Use UL/FM Approved
junction boxes and terminal strips.
Avoid wire splices. However, if wire splices are necessary, Fire Sentry Corporation recommends
soldering all splices. The use of good wiring practices will greatly improve the ease of installation,
improve reliability, and allow easier servicing.
2.1.4
Power Supply Considerations
The Model SS3 Detectors use 12 or 24 volts DC at a maximum current of 40 milliamps. Make sure that
the Panel's power supply can handle the current load of the total number of Model SS3 Detectors
connected to it. For example, if 10 each Model SS3 Detectors are used on one Panel's power supply,
(multiply 10 times 40 milliamps), the Panel's power supply must be able to handle at least 400
milliamps.
This current load must also be considered when calculating the Panel's power backup
requirements for 24 hour backup.
2.2
Detector Installation
Although not required, Fire Sentry Corporation recommends using the Mounting Bracket when installing
the Model SS3 Detector to a wall or junction box.
a. Choose fasteners for the bracket that will secure it solidly to the type of material at the enclosure
location.
b. Mount the bracket to the wall.
c. Install the Model SS3 Detector enclosure onto the bracket
2.3
Wiring Detectors
The Model SS3 Detector may be wired for use on the FS2000 System or to another Control Panel in the
Standalone configuration. Regardless of which type of Controller or System the Detector is wired to the
Fire Relay will function the same. There are several ways to wire the Fire Relay to a Control Panel or
Initiating Circuit. See the manual for the control panel you will be using for specific wiring information.
