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 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 detec­tor 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 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, the sta­tus 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 op­tional Model RA400Z Remote Annunciator to be connected.

Mounting

Each 2100 and 2100T 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.

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.
Twisted pair may be used to provide additional protection
against extraneous electrical interference.

Wire connections are made by stripping about 1/4 inch 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

WARNING

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 the following para­graph.

6. Reset the detector at the system control panel.

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