Mount (Model SM4) for greater flexibility in mounting locations (See Figures 4 and 5). Stand-Alone Operation For Stand-Alone operation, the Model SS4-A/-A2 Detector may be connected to a FM Approved or UL listed Fire/Security Panel. The Detector operated in the Stand-Alone mode uses the Fire, Fault, and Verify (optional) relays to interface to the Fire/Security Panels. -
Page 6: Overview
Re-certification is required if a Fault is indicated by both LEDs rapidly blinking (with frequency about 2 Hz.). Version SS4-A2: The operation of this unit is identical to the SS4-A, except the fire alarm LEDs turn off once the fire threat is eliminated, without power cycling of the device. -

2. Latching / Non-Latching - The Fire Relay and Verify Relay may be set in a Latching or Non-Latching mode. If Latching mode is selected on the SS4-A, the Fire or Verify Relay and red LEDs will remain energized until the Detector power is cycled (power is turned off then on). -
Page 8: 1.6 Testing
For manual testing, the SS4-AUV Detector may be exposed to an actual industry standard open flame or to a Test Lamp simulating a fire. It is mandatory to use the Fire Sentry handheld UV/IR Test Lamp Model No FT-2045 or FT-2145 with SS4 Fire Detectors. The FT-2045 and FT-2145 Test Lamps are housed in an Explosion-Proof enclosure, powered by internal rechargeable batteries, and designed for indoor and outdoor use. -
Page 9: Section 2 Installation
Power Supply Considerations The Model SS4-A/-A2 Detector uses 24 Volts DC at a maximum current of 75 mA (with the 4-20 mA option the maximum supply current is 95 mA). Make sure the Panel's power supply can withstand the load current of the total number of Detectors connected to it. -

Mount the swivel-mount to the wall assuring correct orientation. c. Install the mounting bracket onto the Model SS4-A/-A2 Detector enclosure using the #¼-20 or #6 mm screws and nuts provided. If oriented correctly, the outside contours of the mounting ears on the Detector enclosure and the ends of the bracket will match. - Page 13 Model SS4-A/-A2 Optical Fire Detector Page 10 Installation and Operations Guide 2.95 2.00 4.26 4.86 0.295 Dia. 4.7” approx.

Page 15: Section 3 Troubleshooting And Maintenance
SECTION 3: TROUBLESHOOTING AND MAINTENANCE Model SS4-A/-A2 Detector Faults The Model SS4-A/-A2 Detector issues a Fault (or Trouble) condition by de-energizing its Fault Relay (J5 connector). The following are Detector Faults: a. Temperature Fault: The Detector faults if the internal temperature during operation rises above 80°C or falls below -40°C causing both LEDs to blink rapidly. -

USER SERVICEABLE PARTS IN A ETECTOR MODULE If the Model SS4-A/-A2 Module must be shipped back to the factory for repair, it MUST be packed in static protective material. If not available, the Module should be carefully wrapped with aluminum foil. An RMA (Return Material Authorization) is required for all returns to the factory. -
