Signature Series Intelligence Like all Signature detectors, the SIGA-SD features electronic ad- dressing and issues a dirty sensor warning when it reaches its pre- Dimensions set limit. The dirty sensor warning indicates the sensor is operating 8.70in(22.1cm) within its specified limits but is in need of servicing. When the detec- 8.15in(20.7cm) tor’s ability to compensate for environmental changes has reached 7.75in(19.7cm) 1.60in its limit, the duct smoke detector signals a trouble condition. 3.08in(7.82cm) (4.06cm) The SIGA-SD also uses differential sensing to prevent gradual environmental changes from triggering unwanted alarms. A rapid change in environmental conditions, such as smoke from a fire, causes the detector to signal an alarm state, but dust and debris accumulated over time does not change alarm sensitivity. Each Signature Series SuperDuct detector contains a microproces- sor that performs comprehensive self-diagnostics and stores the results in nonvolatile memory. Stored results include details such as hours of operation, last maintenance date, and number of alarms 2.28in (5.78cm) and troubles. This information can be retrieved and reviewed when desired. Detector Configuration The detector assembly cover provides easy access to the smoke 5.45in (13.84cm) sensor, its wiring connections, sample and exhaust tubes, and the smoke chamber itself. Air enters the detector’s sensing chamber through a sampling tube (ordered separately) that extends into the duct and is directed back into the ventilation system through an exhaust tube (included). The 1.90in difference in air pressure between the two tubes pulls the sampled (4.83cm) air through the sensing chamber. When a sufficient amount of smoke is detected in the sensing chamber, the detector initiates an alarm. The sampling tube may be installed from either the duct side of the 1.38in 5.40in (3.51cm) (13.72cm) Data Sheet 85001-0584 Issue 4 Not to be used for installation purposes.
