Application Testing & Maintenance The SIGA-OSD detects particles from a wide range of combustion sources and will trigger an alarm when smoke density in the chamber reaches preprogrammed level. Thanks to its high- performance reflective response technology, the smoke sensor responds quickly and reliably to a wide range of fire types, including both fast and slow burning fires fueled by combustibles typically found in modern multi -use buildings. Compatibility The SIGA-OSD detector is compatible only with control panels using a Signature Loop controller. Installation Signature Series detectors mount to North American 1-gang boxes, 3-1/2 inch or 4 inch octagon o 0 boxes, and to 4 inch square Self-locking tab electrical boxes 1-1/2 inches (38 mm) deep. They mount to European BESA and 1-gang boxes with 60.3 mm fixing LED Indicator centers. See mounting base installation and wiring for more information. Sensing and reporting technology The microprocessor in each detector provides additional benefits — Self -diagnostics and History Log, Automatic Device Mapping, and Fast, Stable Communication. Self -diagnostics and History Log - Each Signature Series detector constantly runs self -checks to provide important maintenance information. The results of the self -check are automatically updated and permanently stored in the detector's non-volatile memory Automatic Device Mapping - The loop controller learns where each device's serial number address is installed relative to other devices on the circuit. The mapping feature provides supervision of each device's installed location to prevent a detector from being reinstalled (after cleaning, etc.) in a different location from where it was originally. Fast Stable Communication - On -board intelligence means less information needs to be sent between the detector and the loop controller. Other than regular supervisory polling response, the detector only needs to communicate with the loop controller when it has something new to report. Each detector automatically identifies when it is dirty or defective and causes a "dirty detector" message. The detector's sensitivity measurement can also be transmitted to the loop controller. A sensitivity report may be printed to satisfy NFPA sensitivity measurements, which must be conducted at the end of the first year and every two years thereafter. The user-friendly maintenance program shows the current state of each detector and other pertinent messages. Single detectors may be turned off temporarily from the control panel. Availability of maintenance features is dependent on the fire alarm system used. Accessories Detector mounting bases have wiring terminals that are accessible from the "room -side" after mounting the base to the electrical box. The bases mount to North American 1-gang boxes and to 3'/2 inch or 4 inch octagon boxes, 1 t/2 inches (38 mm) deep. They also mount to European BESA and 1-gang boxes with 60.3 mm fixing centers. The SIGA-SB4, SIGA-RB4, and SIGA-I134 mount to North American 4 inch sq. electrical boxes in addition to the above boxes. They include the SIGA-TS4 Trim Skirt, which is used to cover the "mounting ears" on the base. The SIGA-AB4G mounts to a 4 inch square box only. I SIGA-AB4G/T/LF SIGA-SB SIGA-IB SIGA-RB SIGA-LED Audible Base Standard Base Isolator Base Relay Base Remote LED Remote LED SIGA-LED - The remote LED connects to the SIGA-SB or SIGA-SB4 Standard Base only. It features a North American size 1-gang plastic faceplate with a white finish and red alarm LED. SIGA-TS4 Trim Skirt - Supplied with 4 inch bases, it can also be ordered separately to use with the other bases to help hide surface imperfections not covered by the smaller bases. Sounder Bases - Signature Series sounder bases are designed for use where localized or group alarm signaling is required. • SIGA-AB4G bases provide sounder capability to Signature Series to heat and smoke detectors. They are not intended for use with combination carbon monoxide detectors in Fire -plus -CO mode. • SIGA-AB4GT bases provide sounder capability to Signature Series smoke and heat detectors, as well as carbon monoxide detectors when used with a SIGA-TCDR Temporal Pattern Generator. • SIGA-AB4G-LF bases provide 520 Hz low frequency sounder capability to Signature Series smoke and heat detectors, as well as carbon monoxide detectors when used with a SIGA-TCDR Temporal Pattern Generator. The SIGA-AB4G-LF is suitable for applications requiring low frequency audible tones. Page 2 of 4 DATA S H E EE85001-1001 Not to be used for installati ,oses. Issue 1.4
