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.
Tamper-resistant Feature
This detector includes a tamper-resistant feature that pre-
vents 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, lo-
cated in the slot on the mounting bracket, and turn the de-
tector counterclockwise.
Wiring Installation Guidelines
All wiring must be installed in compliance with the Na-
tional Electrical Code, applicable local codes, and any spe-
cial 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
control panel specifications for the total loop resistance al-
Before Installing
Please thoroughly read the 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 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 com-
patible 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 sensi-
tivity range, the status LED blinks every ten seconds. The
LED also latches on in alarm. If the LED stops blinking, the

lowed for the control panel being used before wiring the
detector loops.
System Sensor smoke detectors are marked with a compat-
ible 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.
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.
Installation
WARNING
Remove power from the control unit or initiating device cir-
cuits before installing detectors.
1. Wire the plug-in screw terminal block per Figure 1 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 un-
til 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.
6. Reset the detector at the system control panel.
7. Notify the proper authorities the system is in operation.
CAUTION
Dust covers are an effective way to limit the entry of dust
into smoke detector sensing chambers. However, they may
not completely prevent airborne dust particles from enter-
ing the detector. Therefore, System Sensor recommends the
removal of detectors before beginning construction or other
dust producing activity. Be sure to remove dust covers from
any sensors that were left in place during construction as
part of returning the system to service.

Testing
NOTE: Before testing, notify the proper authorities that
the smoke detector system is undergoing mainte-
nance and will be temporarily out of service. Dis-
able the zone or system undergoing maintenance
to prevent unwanted alarms.
Detectors must be tested after installation and following
periodic maintenance. Test the 2100TR as follows:
A. Test Switch
1. A recessed test switch is located on the detector hous-
ing (See Figure 4).
2. Press and hold the recessed test switch with a 0.18
inch maximum diameter tool such as an allen wrench
or small screwdriver.
3. The detector’s LED should light within 5 seconds.
B. Test Module (System Sensor Model No. MOD400R).
The MOD400R test module can be used with a DMM or
analog voltmeter to check the detector sensitivity as de-
scribed in the test module’s manual.
C. Smoke Entry Test
Hold a smoldering punk stick or cotton wick at the side
of the detector and gently blow smoke through the de-
tector until the unit alarms.
D.Direct Heat Method (Hair dryer of 1000-1500 watts)
Direct the heat toward either of the side thermistors.
Hold the heat source about 12 inches from the detector
in order to avoid damage to the plastic. The detector will
reset only after it has had sufficient time to cool and the
power source has been momentarily interrupted.
Both smoke and heat detection testing are recommended
for verifying system protection capability.
A detector that fails to activate with any of the above tests
should first be cleaned as outlined in MAINTENANCE. If
the detector still fails to activate, return it for repair.
Notify the proper authorities the system is back in
operation.
Maintenance
NOTE: Before removing the detector, notify the proper au-
thorities that the smoke detector system is under-
going maintenance and will be temporarily out of
service. Disable the zone or system undergoing
maintenance to prevent unwanted alarms.
NOTE: Before removing the detector cover, note the posi-
tion of the thermistors. Make sure the thermistors
are not bent over when the housing is replaced.
1. Remove the detector housing by gently prying the four
housing tabs on the bottom of the base with a small-
bladed screwdriver and pull the housing from the base.
Use caution to avoid damaging the thermistors.

Three-Year Limited Warranty
System Sensor warrants its enclosed smoke detector to be free from de-
fects in materials and workmanship under normal use and service for a
period of three years from date of manufacture. System Sensor makes no
other express warranty for this smoke detector. No agent, representative,
dealer, or employee of the Company has the authority to increase or alter
the obligations or limitations of this Warranty. The Company’s obligation
of this Warranty shall be limited to the repair or replacement of any part of
the smoke detector which is found to be defective in materials or work-
manship under normal use and service during the three year period com-
mencing with the date of manufacture. After phoning System Sensor’s toll
free number 800-SENSOR2 (736-7672) for a Return Authorization number,
send defective units postage prepaid to: System Sensor, Repair Depart-
ment, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please
include a note describing the malfunction and suspected cause of failure.
The Company shall not be obligated to repair or replace units which are
found to be defective because of damage, unreasonable use, modifica-
tions, or alterations occurring after the date of manufacture. In no case
shall the Company be liable for any consequential or incidental damages
for breach of this or any other Warranty, expressed or implied whatsoever,
even if the loss or damage is caused by the Company’s negligence or fault.
Some states do not allow the exclusion or limitation of incidental or conse-
quential damages, so the above limitation or exclusion may not apply to
you. This Warranty gives you specific legal rights, and you may also have
other rights which vary from state to state.
This smoke detector is designed to activate and initiate emergency ac-
tion, but will do so only when it is used in conjunction with an authorized
fire alarm system. This detector must be installed in accordance with
NFPA standard 72. (For installation in Canada, refer to CAN/ULC-S524-
M91, Standard for the Installation of Fire Alarm Systems, and CEC Part 1,
sec. 32.)
Smoke detectors will not work without power. AC or DC powered
smoke detectors will not work if the power supply is cut off.
Smoke detectors will not sense fires which start where smoke does not
reach the detectors. Smoldering fires typically do not generate a lot of
heat which is needed to drive the smoke up to the ceiling where the
smoke detector is usually located. For this reason, there may be large de-
lays in detecting a smoldering fire with either an ionization type detector
or a photoelectric type detector. Either one of them may alarm only after
flaming has initiated which will generate the heat needed to drive the
smoke to the ceiling.
Smoke from fires in chimneys, in walls, on roofs or on the other side of a
closed door(s) may not reach the smoke detector and alarm it. A detector
cannot detect a fire developing on another level of a building quickly or at
all. For these reasons, detectors shall be located on every level and in
every bedroom within a building.
Smoke detectors have sensing limitations, too. Ionization detectors and
photoelectric detectors are required to pass fire tests of the flaming and
smoldering type. This is to ensure that both can detect a wide range of
types of fires. Ionization detectors offer a broad range of fire sensing capa-
bility but they are somewhat better at detecting fast flaming fires than
slow smoldering fires. Photoelectric detectors sense smoldering fires better
than flaming fires which have little, if any, visible smoke. Because fires de-
velop in different ways and are often unpredictable in their growth, nei-
ther type of detector is always best, and a given detector may not always
provide early warning of a specific type of fire.
In general, detectors cannot be expected to provide warnings for fires re-
sulting from inadequate fire protection practices, violent explosions, es-
caping gases which ignite, improper storage of flammable liquids like
cleaning solvents which ignite, other similar safety hazards, arson, smok-
ing in bed, children playing with matches or lighters, etc. Smoke detectors
used in high air velocity conditions may have a delay in alarm due to dilu-
tion of smoke densities created by frequent and rapid air exchanges. Addi-
tionally, high air velocity environments may create increased dust
contamination, demanding more frequent maintenance.
To keep your equipment in excellent working order, ongoing maintenance
is required per the manufacturer’s recommendations and UL and NFPA
standards. At a minimum, the requirements of Chapter 7 of NFPA 72, the
National Fire Alarm Code, shall be followed. A preventative maintenance
agreement should be arranged through the local manufacturer’s represen-
tative. Though smoke detectors are designed for long life, they may fail at
any time. Any smoke detector, fire alarm equipment, or any component of
that system which fails shall be repaired or replaced as soon as possible.
