Application Testing & Maintenance The SIGA-OSD detects particles from a wide range of combustion Each detector automatically identifies when it is dirty or defective sources and will trigger an alarm when smoke density in the and causes a"dirty detector"message.The detector's sensitivity chamber reaches preprogrammed level.Thanks to its high- measurement can also be transmitted to the loop controller. performance reflective response technology,the smoke sensor A sensitivity report may be printed to satisfy NFPA sensitivity responds quickly and reliably to a wide range of fire types, measurements,which must be conducted at the end of the first including both fast and slow burning fires fueled by combustibles year and every two years thereafter. typically found in modern multi-use buildings. The user-friendly maintenance program shows the current state of each detector and other pertinent messages. Single detectors Compatibility may be turned off temporarily from the control panel.Availability of maintenance features is dependent on the fire alarm system used. The SIGA-OSD detector is compatible only with control panels using a Signature Loop controller. - Accessories Installation Detector mounting bases have wiring terminals that are accessible from the"room-side"after mounting the base to the Signature Series detectors mount electrical box.The bases mount to North American 1-gang boxes to North American 1-gang boxes and to 31/2 inch or 4 inch octagon boxes, 11h inches(38 mm) 3-1/2 inch or 4 inch octagon _ =' deep.They also mount to European BESA and 1-gang boxes with boxes,and to 4 inch square sesr-loca"9 tab 60.3 mm fixing centers.The SIGA-SB4, SIGA-RB4, and SIGA-IB4 electrical boxes 1-1/2 inches mount to North American 4 inch sq. electrical boxes in addition to (38 mm)deep.They mount to ' the above boxes.They include the SIGA-TS4 Trim Skirt,which is European BESA and 1-gang r used to cover the"mounting ears"on the base.The SIGA-AB4G boxes with 60.3 mm fixing5 ' .n Indicator mounts to a 4 inch square box only. centers.
