Before Installing

Please thoroughly read System Sensor manual I56-407, 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.

NOTICE: This manual shall 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 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.

Specifications

Diameter: 5.5 inches (140 mm) Height (including mounting bracket): 1.9 inches (48 mm) Weight: 5.3 oz. (150 g) Operating Temperature Range: Model 2100S: 32° to 120°F (0° to 50°C)

Model 2100TS: 32° to 100°F (0° to 38°C) Operating Humidity Range: 10% to 93% Relative Humidity, Noncondensing Latching Alarm: Reset by momentary power interruption Heat Sensor (Model 2100TS 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 130 mA.

(Alarm current must be limited to 130 mA maximum by the control panel. If

used, the RA400Z Remote Annunciator operates 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. 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 maintenance 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.

Mounting

Each 2100S and 2100TS detector is supplied with a mounting bracket that permits the detector to be mounted:

1. To a single gang box, or

2. Directly to a 31/2-inch or 4-inch octagonal box, or

3. To a 4 inch square electrical box by using a plaster ring.

4. Directly to the ceiling using drywall anchors, if permitted by local codes and/or the authority having jurisdiction.

Tamper-resistance Feature

This detector includes a tamper-resistant feature that prevents its removal from the bracket without the use of a tool. To make the detector tamper-resistant, remove the smaller tab by breaking it at the scribed line on the tamper-resistant tab on the detector mounting bracket (see Figure 2), then install the detector. To remove the detector from the bracket once it has been made tamper resistant, use a small screwdriver to depress the tamper-resistant tab, located in the slot on the mounting bracket, and turn the detector counterclockwise.

Wiring Installation Guidelines

All wiring must be installed in compliance with the National Electrical Code, applicable local codes, and any special requirements of the local authority having jurisdiction. Proper wire gauges should be used. The conductors used to connect smoke detectors to control panels and

accessory devices should be color-coded to reduce the likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire.

The screw terminal block will accept 14 – 22 gauge wire. For best system performance, all wiring should be installed in separate grounded conduit; do not mix fire system wiring in the same conduit as any other electrical wiring. Tw isted pair may be used to provide additional protection against extraneous electrical interference.

Wire connections are made by stripping about 1/4inch of insulation from the end of the feed wire, inserting the wire into the appropriate terminal, and tightening the screw to secure the wire in place.

System Sensor smoke detectors are marked with a compatibility identifier located as the last digit of a five digit code stamped on the back of the product. Connect detectors only to compatible control units as indicated in System Sensor’s compatibility chart which contains a current list of UL listed compatible control units and detectors. A copy of this list is available from System Sensor upon request.

Installation

Remove power from the control unit or initiating-device circuits before installing detectors.

1. Wire the plug-in screw terminal block per Figure 3 and plug the terminal block into the detector.

2. Align the arrows on the detector with the arrows on the mounting bracket.

3. Turn the detector clockwise in the mounting bracket until it clicks into place.

4. After all detectors have been installed, apply power to the control unit or initiating-device circuits.

5. Test the detector as described in TESTING. (See page 3.)

6. Reset the detector at the system control panel.

7. Notify the proper authorities the system is in operation.
