General Description
Model 2100 is a 2-wire photoelectronic smoke detector that uses a state-of-the-art optical sensing chamber. This detector is designed to provide open area protection and to be used with compatible UL-listed panels only. Model 2100T features a restorable, built-in, fixed-temperature (135° F) thermal detector.
Installation of these detectors is simplified by the use of a mounting bracket and a plug-in screw terminal block that can be prewired to the system, allowing the detector to be easily installed or removed for cleaning. The detector’s sensitivity can be tested in place using the MOD400R Test Module. An LED on the detector provides a local visual in dication of the detector’s status. If power is applied to the detector, and it is functioning normally in standby, the status LED blinks every ten seconds. The LED also latches on in alarm.
Models 2100 and 2100T feature a visual indication that maintenance is required – if the sensing chamber drifts out of its sensitivity limits, the LED ceases to blink.
The detectors also include an output that allows an optional Model RA400Z Remote Annunciator to be connected.
