INSTALLATION AND MAINTENANCE INSTRUCTIONS
FOR MODEL 2300TB
Before installing detectors, please thoroughly read System Sensor Manual I56-407-XX,
Guide for Proper Use of System Smoke
Detectors,
which provides detailed information on detector spacing, placement, zoning, wiring, and special applications. Copies
of this manual are available at no charge from System Sensor.
GENERAL DESCRIPTION:
Model 2300TB is a 2-wire combination smoke/heat detector. In addition to photoelectronic smoke detection, two supervised
electronic thermistors provide restorable 135°F fixed temperature heat detection. The installation is simplified by the use of an
adaptor bracket and a plug-in screw terminal block which can be pre-wired to the system allowing the detector to be easily
installed or removed for cleaning. It is designed to provide open area protection, and to be used with UL listed compatible 2-
wire control panels. The detector’s sensitivity can be tested in place using the MOD400R field sensitivity test module.
The 2300TB is listed to UL 268 and is a latching type system detector. When latched in alarm, the detector must be reset by
a momentary power interruption.
An LED on the detector provides a local indication of the detector’s status. If power is applied to the detector, and the detector
is functioning properly in standby, the status LED will blink every 10 seconds. The detector performs a self-test on its smoke
sensing chamber and internal electronics every 40 seconds. If this test fails, the detector stops blinking the status LED in
standby, and the LED will remain off. In alarm, the LED will be latched on continuously until the detector is reset.
The detector provides an output for connection to an optional Remote Annunciator (model RA400Z). The Remote Annunciator
mounts to a single gang box and provides an LED indication of an alarm condition.
