Application Accessories The SIGA-HRD combination fixed temperature/rate-of-rise heat detector provides a 15 °F (9 °C) per minute rate -of -rise heat sen- sor for the detection of fast -developing fires, as well as a 135°F (57°C) fixed temperature sensor for slow building -fires. The SIGA- HFD fixed temperature detector provides a 135°F (57°C) fixed temperature sensor for slow building -fires. Compatibility Signature Series heat detectors are compatible only with the Sig- nature Loop Controller. Installation Signature Series detectors mount to North American 1-gang boxes, 3-1/2 inch or 4 inch octagon boxes, and to 4 inch square elec- Self-locking tab trical boxes 1-1/2 inches (38 mm) deep. They mount to European BESA and 1-gang boxes with 60.3 Z mm fixing centers. See mounting LED Indicator 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 mainte- nance 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. Detector mounting bases have wiring terminals that are acces- sible 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'h 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. - 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 monox- ide 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 detec- tors, 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. Warnings & Cautions • This detector does not operate without electrical power. As fires frequently cause power interruption, discuss further safe- guards with the local fire protection specialist. • This detector does not sense fires in areas where heat cannot reach the detector. Heat from fires in walls, roofs, or on the opposite side of closed doors may not reach the detector. • This heat detector by itself does not provide life safety protec- tion Use this detector with ionization and/or photoelectric smoke detectors. • This detector does not detect oxygen levels, smoke, toxic gases, or flames. Use this device as part of a broad -based life safety program which includes a variety of information sources pertaining to heat and smoke levels, extinguishment systems, visual and audible devices, and other safety mea- sures. • Independent studies indicate that heat detectors should only be used when property protection alone is involved. Never rely on heat detectors as the sole means of fire protection. Page 2 of 4 DATA SHEET E85001-0647 Not to be used for installation purposes. Issue 2.2
