Introduction
The Model SS2 Multi-Spectrum Electro-Optical Fire/Flame Detectors may
be used in the FS2000 Fire Early Warning System or in the Stand-Alone
mode. Detectors of this model are housed in Explosion-Proof Class I, Div.
1 enclosures. The only difference between an FS2000 System Model SS2
Detector and a Stand-Alone SS2 Detector is in the wiring. The wiring
differences are described in Sections 1.2 and 1.3.
Model SS2-A Detectors have a latching relay. They are used for
hydrocarbon and non-hydrocarbon fires
Model SS2-AN Detectors have a non-latching relay. They are otherwise
identical to the SS2-A.
Model SS2-AH is the same as Model SS2-A except for the programming to
assure High Speed millisecond response to non-UV emitting sodium azide
fires (in addition to the normal fire response) for air bag industries. The
Detector is housed in a Class I, Div. 1 Explosion-Proof enclosure. For more
information, refer to corresponding specification sheets.
Model SS2-AM is the same as Model SS2-A except for the programming to
assure Ultra High Speed millisecond response to normal non-sodium azide
burning materials radiating UV and IR energy for munitions and air bag
industries. The Detector is housed in a Class I, Div. 1 Explosion-Proof
enclosure. For more information, refer to corresponding specification
sheets.
There are operational advantages when the Detector is connected to an
FS2000 Controller and FireBus. The Detector also has flexibility to be re-
configured in the field. It is simple to install and operate due to built in self-
testing. The maintenance consists in wiping the lens and performing
periodic testing required by the manufacture of the Fire Control and
Suppression Systems.

Stand-Alone Operation
The Model SS2 Detectors may be connected to an approved Fire/Security
Panel for Stand-Alone operation. The Detectors operate on 24 Volts DC. In
this mode the Detectors utilize Fire and Fault relays to interface to FM/UL
approved Fire/Security Panels. For Stand-Alone operation, the Detector's
Fault relay is automatically configured by the on-board microprocessor.
The input current of the Detector is about 15 mA higher in the Stand-Alone
mode compared to operation as part of FS2000 System.
