Page 10: Stand-Alone Operation
FS2000 System. FS2000 System Operation For FS2000 System operation, the Model SS4-AS/-AS2 Fire and Fault signals are sent digitally to the FS2000 System Controller using the four wire FS2000 FireBus. The FireBus provides 24 Volt DC power for the Detector and RS-485 digital communication (Refer to Honeywell Analytics document MN0003: "FS2000 FIRE EARLY WARNING SYSTEM - INSTALLATION and... -
Page 11: Overview
Overview 1.4.1 Model SS4-AS/-AS2 Detector Version SS4-AS: There are two (2) LEDs on the Model SS4-AS Detector that indicate the state of the Detector. During normal operation both LEDs will blink every 10 seconds. If the Detector alarms to a fire, it energizes the Fire relay and turns on both LEDs in the following sequence. -
Page 12: Detection Range And Field-Of View
TECHNICAL DESCRIPTION 1.4.2 Detection Range and Field-of View The SS4-AS detection range is field adjustable between 15 and 60 ft. in 15 ft. increments to an industry-standard one square foot heptane, gasoline, kerosene, or isopropyl alcohol pan fire within 5 seconds. -
Page 13: Configuration Settings
Sensitivity to 1 Sq. Ft. Gasoline Pan Fire Configuration Settings The SS4-AS/-AS2 Detector may be reconfigured in the field and thus optimized for special applications. The configuration of the Detector is set from a DIP switches located on the middle circuit board of the Detector Module. The DIP switch settings for each configuration are listed in Table 2. - Page 14 Latching or Non-Latching mode. The Factory setting for the SS4-AS is Latching and the SS4-AS2 is Non-Latching. If the SS4-AS or SS4-AS2 Latching mode is selected, the Fire or Verify Relay will energize and Red LEDs will remain illuminated until the Detector power is cycled (power is turned off then on).

Page 24: Cleaning Windowed Enclosures And Detectors
TROUBLESHOOTING AND MAINTENANCE Cleaning Windowed Enclosures and Detectors The optical window (lens) of the Model SS4-AS/-AS2 Detector should be cleaned periodically on a regular maintenance schedule. For clean area applications, perhaps monthly cleaning schedule will be sufficient. For extremely contaminated application environments, such as truck filling stations with presence of black carboneous smoke, daily cleaning schedule may be necessary. -
Page 25: Detector Repair
Return the defective module to the factory for repair service. There are no user serviceable parts in the detector module If the Model SS4-AS/-AS2 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. -
