detector sensitivity Built in test capability Low standby current Twist on mounting bracket with tamper option Designed for direct surface or electrical box mounting Models available with built in 85 dBA piezoelectric horn Insect resistant screening with 0.020 0.508 mm open Isolated or integrated operation of thermal available cer models SEMS screws for easy wiring Meets performance criteria designated by UL 268 Built to withstand air velocities up to 3,000 feet 914.4 per minute without triggering a false alarm to contribute to life safety fire protection and property Photoelectric detectors are recommended areas where smoldering fires are likely to ignite In ar where small combustion particles are usually present forklift trucks cooking stoves etc they are less likely ionization detectors to produce false alarms further information see System Sensor manual I56 cid 147 Applications Manual for System Smoke Detectors cid 148 provides detailed information on detector spacing zoning wiring and special applications AND OPERATION 2400 Series photoelectric smoke detectors contain a optical sensing chamber designed to sense the of smoke particles produced by a wide range of sources A custom integrated circuit incorpo signal processing to reduce false alarms and sample circuitry to provide easy field metering of sensitivity optional built in piezo horn produces an interrupted 85 tone at 10 feet 3.048 m The horn operates upon reversal of the supply voltage when the unit senses or when the thermal reaches its alarm point inte thermal models only document is

2412TH and 2424TH with thermal sensor rated 135 cid 176 F 57 cid 176 C as manufactured by System Sensor Wir connections shall be made by means of SEMS screws detector will have a visible LED which will blink in and latch on in alarm The sensor shall have a sensitivity of 3.0 per foot as measured In a UL box The detector screen and cover should be eas removable for cleaning It shall be possible to perform a and functional test on the detector without need to generate smoke Detector circuitry shall perform a on the sensing chamber and internal electronics 40 seconds If circuitry fails the detector LED shall blinking The detector LED shall stop blinking The shall have a mounting bracket that allows for di surface mounting or mounting to a 3 1 2 88.9 mm 4 101.6 mm octagonal box
