2100 and 2100T Photoelectronic Smoke Detectors INSTALLATION AND MAINTENANCE INSTRUCTIONS A Division of Pittway 3825 Ohio Avenue, St. Charles, Illinois 60174 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. Specifications Diameter: 5.5 inches (140 mm) Height (including mounting bracket): 1.7 inches (43 mm) Weight: 5.3 oz. (150 g) Operating Temperature Range: Model 2100: 32 ° to 120°F (0° to 50°C) Model 2100T: 32 ° to 100°F (0° to 39°C) Operating Humidity Range: 10% to 93% Relative Humidity, Noncondensing Latching Alarm: Reset by momentary power interruption Heat Sensor (Model 2100T only): 135 °F Fixed Temperature Electronic Thermistor Electrical Ratings System Voltage Nominal: 12 or 24 VDC Minimum: 8.5 VDC Maximum: 35 VDC Maximum Ripple Voltage: 30% of nom. Voltage (peak to peak) Start-up Capacitance: 0.02 µF maximum Standby Current: 50 µA maximum Alarm Ratings: 4.2 VDC minimum at 10 mA. 6.6 VDC maximum at 100 mA. (Alarm current must be limited to 100 mA maximum by the control panel. If used, the RA400Z Remote Annunciator oper- ates within the specified detector alarm currents.) Reset Voltage: 2.5 VDC minimum Reset Time: 0.3 seconds maximum Start-up Time: 30 seconds maximum (after 60 second reset) 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.
