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 2100D 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
2100TD features a restorable, built-in, xed-temperature
(135°F) thermal detector.
Installation of these detectors is simplied 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 2100D and 2100TD 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.

WARNING
on 3 1/2-inch and 4-inch octagonal box:
A78-2563-00
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 re 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.
Mounting
Each 2100D and 2100TD 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.
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 tamperresistant 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 re.
System Sensor smoke detectors are marked with a compatibility identier located as the last digit of a ve 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 the following
paragraph.
6. Reset the detector at the system control panel.
7. Notify the proper authorities the system is in operation.
