System sensor 2412 photoelectric smoke detector/4WIRES
The System Sensor 2412 and 2424, Four-wire photoelectric smoke detectors utilize stated-of-the-art, optical sensing chambers. These detectors are designed to provide open area protection, and to be used with compatible UL-listed 4-wire control panels only. The 2412 applies to 12 volt panels and operates at 12VDC, and the 2424 applies to 24 volt panels and operates at 24VDC.
Operation and sensitivity can be tested in place. Models 2412TH and 2424TH have the same specifications as models 2412 and 2424, but in addition feature a built-in fixed temperature (135 F. degrees) Thermal detection unit.
* Diameter: 5.5 inches (14 cm)
* Height: 3.19 inches (81 mm); Add 0.5 inches (1.3 cm) for thermal units
* Operating Temperature Range: 2412 and 2424 0 C to +49 C (32 F to 120 F)
* 2412TH and 2424TH 0 to +38 C (32 to 100 F)
* Operating Humidity Range: 10% to 93% Relative Humidity
* Maximum Air Velocity: 3000 Ft./Min. (15 M/S)
* Latching Alarm: Reset by momentary power interruption.
