General Description

Model 2100S 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 2100TS 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. The detector’s sensitivity can be tested in place using the MOD400R Test Module. An LED on the detector provides a local visual indication of the detector’s status. If power is applied to the detector, and it is functioning normally in standby mode within the listed sensitivity ranges, the status LED blinks once every ten seconds. The LED also provides a visual indication that main tenance is required. If the LED stops blinking, the detector is either not powered, out of the listed sensitivity range, and/or unable to function properly. The test switch will not operate if the detector is below the insensitive limit. The LED will also latch on when the detector is in alarm.

The detectors also include an output that allows an optional Model RA400Z Remote Annunciator to be connected.
