EST 85001-0269 — Intelligent PS Multisensor Detector

GE Fire Life Safety Initiating Devices Signature Series Model SIGA PS Intelligent Photoelectric Smoke gathers analog information from its smoke sensing ele and converts it into digital signals The detector on board measures and analyzes these signals It compares information to historical readings and time patterns to make alarm decision Digital filters remove signal patterns that are not of fires Unwanted alarms are virtually eliminated microprocessor in each detector provides four additional benefits Self diagnostics and History Log Automatic Device Mapping Operation and Fast Stable Communication and History Log Each Signature Series detec constantly runs self checks to provide important maintenance The results of the self check are automatically updated permanently stored in the detector non volatile memory Device Mapping The loop controller learns where each serial number address is installed relative to other devices the circuit The mapping feature provides supervision of each installed location to prevent a detector from being rein after cleaning etc in a different location from where it was Operation A decentralized alarm decision by the is guaranteed On board intelligence permits the detector operate in stand alone mode If loop controller CPU communica fail for more than four seconds all devices on that circuit go stand alone mode The circuit acts like a conventional alarm circuit Stable Communication On board intelligence means less needs to be sent between the detector and the loop Other than regular supervisory polling response the only needs to communicate with the loop controller when has something new to report Standard Features microprocessor memory mapping device addressing compensation detector 0.67 to 3.77 ft sensitivity range pre alarm sensitivity values set in 5 increments of dirty or defective detectors day night sensitivity adjustment RED GREEN status LEDs relay fault isolator and audible mounting bases and manufactured to ISO 9001 standards Detector Notes Sheet 85001 0269 Issue 6 to be used for installation purposes Page 1 of 4 Series detectors mount to North American 1 gang boxes inch or 4 inch octagon boxes and to 4 inch square electrical 1 1 2 inches 38 mm deep They mount to European BESA 1 gang boxes with 60.3 mm fixing centers Maintenance detector automatically identifies when it is dirty or defective causes a detector message The detector sensitiv measurement can also be transmitted to the loop controller A report can be printed to satisfy NFPA sensitivity measure which must be conducted at the end of the first year and two years thereafter user friendly maintenance program shows the current state each detector and other pertinent messages Single detectors be turned off temporarily from the control panel Availability of features is dependent on the fire alarm system used maintenance Regular or Selected for proper detector should be planned to meet the requirements of the Au Having Jurisdiction AHJ Refer to current NFPA 72 and ULC 536 standards SIGA PS detectors are compatible only with the Signature Loop Cautions detector will not operate without electrical power As fires fre cause power interruption we suggest you discuss further with your fire protection specialist detector will NOT sense fires that start in areas where smoke reach the detector Smoke from fires in walls roofs or on the side of closed doors may not reach the detector to alarm it detector mounting bases have wiring terminals that are acces from the after mounting the base to the electrical The bases mount to North American 1 gang boxes and to 3 or 4 inch octagon boxes 1 inches 38 mm deep They also to European BESA and 1 gang boxes with 60.3 mm fixing The SIGA SB4 SIGA RB4 and SIGA IB4 mount to North 4 inch sq electrical boxes in addition to the above boxes include the SIGA TS4 Trim Skirt which is used to cover the ears on the base The SIGA AB4G mounts to a 4 sqare only Base Base Base Base LED Base SIGA SB SIGA SB4 This is the basic mounting for GE Security Signature Series detectors The SIGA LED LED is supported by the Standard Base Base SIGA RB SIGA RB4 This base includes a relay Nor open or closed operation is selected during installation The contact is rated for 1 amp pilot duty 30 Vdc The relay position supervised to avoid accidentally jarring it out of position The SIGA can be operated as a control relay if programmed to do so at control panel EST3 V 2 only The relay base does not support SIGA LED Remote LED Base SIGA AB4G This base is designed for use where or group alarm signaling is required When the detector an alarm condition the audible base emits a local alarm The optional SIGA CRR Polarity Reversal Relay can be used for to other audible bases on the same 24 Vdc circuit and Audible Bases operate as follows at system power up or reset the relay is de energized when a detector is installed in the base with the power on the relay energizes for four seconds then de energizes when a detector is removed from a base with the power on the relay is de energized when the detector enters the alarm state the relay is energized Base SIGA IB SIGA IB4 This base includes a built in line isolator for use on Class A circuits A detector must be installed it to operate The isolator base does not support the SIGA LED LED isolator operates as follows a short on the line causes all isolators to open within 23 msec at 10 msec intervals beginning on one side of the Class A nearest the loop controller the isolators close to the next isolator down the line with power when the isolator next to the short closes reopens within 10 msec process repeats beginning on the other side of the loop con LED SIGA LED The remote LED connects to the SIGA SB SIGA SB4 Standard Base only It features a North American size plastic faceplate with a white finish and red alarm LED Trim Skirt Supplied with 4 inch bases it can also be separately to use with the other bases to help hide surface not covered by the smaller bases Sheet 85001 0269 Issue 6 to be used for installation purposes Page 2 of 4 photoelectric detectors have a wide range of fire sensing capabilities they are best suited for detecting slow smoldering fires The below shows six standard test fires used to rate the sensitivity of smoke and heat detectors The table indicates that no single sensing is suited for all test fires Security recommends that this detector be installed according to latest recognized edition of national and local fire alarm codes Fire Wood Pyrolysis Cotton Urethane Foam Fire without Smoke Ion
