Before Installing

Please thoroughly read the 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 following NFPA 72 requirements. The detector should be cleaned at least once a year.

General Description

Model 2100TR is a 2-wire photoelectronic smoke detector that uses a state-of-the-art optical sensing chamber. This detector also provides restorable, 135˚F fixed-temperature heat detection. The 2100TR heat-detection unit is integrated with the photoelectronic sensor. This detector is designed to provide open area protection and to be used with compatible UL-listed panels only.

Installation of this detector 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 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 within the listed sensitivity range, the status LED blinks every ten seconds. The LED also latches on in alarm. If the LED stops blinking, the unit should be removed for maintenance and inspection.

The detectors also include an output that allows optional connection of the RA400Z Remote Annunciator.

Mounting

Each 2100TR 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 3-1/2 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-resistant 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

3), 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 accepts 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. Twisted pair may be used to provide additional protection against electrical interference.

Smoke detectors and alarm system control panels have specifications for allowable loop resistance. Consult the
