1-800-SENSOR2, FAX: 630-377-6495

Before Installing

Please thoroughly read System Sensor manual I56-407,

Guide for Proper Use of System Smoke Detectors, which pro-

vides detailed information on detector spacing, placement,

zoning, wiring, and special applications. Copies of this

manual are available at no charge from System Sensor.

NOTICE: This manual should be left with the owner/user

of this equipment.

IMPORTANT: This detector must be tested and maintained

regularly following NFPA 72 requirements. The detector

should be cleaned at least once a year.

General Description

Model 2100 is a 2-wire photoelectronic smoke detector that

uses a state-of-the-art optical sensing chamber. This detec-

tor 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 sen-

sitivity 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 sta-

tus 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 op-

tional Model RA400Z Remote Annunciator to be connected.
