General Description
Model 2100D is a 2-wire photoelectronic smoke detector
that uses a state-of-the-art optical sensing chamber. This The detectors also include an output that allows an optional
detector is designed to provide open area protection and Model RA400Z Remote Annunciator to be connected.
to be used with compatible UL-listed panels only. Model
2100TD features a restorable, built-in, fixed-temperature
(135°F) thermal detector.

C. Smoke Entry Test
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 en-
tering 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.
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 (Model 2100TD only – 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.
Testing
NOTE: Before testing, notify the proper authorities that the
smoke detector system is undergoing maintenance
and will temporarily be out of service. Disable the
zone or system undergoing maintenance to prevent
unwanted alarms.
Detectors must be tested after installation and following
periodic maintenance. Test the 2100D as follows:
A. Test Switch
A detector that fails to activate with any of the above tests
should first be cleaned as outlined in the MAINTENANCE
section which follows. If the detector still fails to activate, it
should be returned for repair.
1. A recessed test switch is located on the detector hous-
ing (See Figure 4).
2. Push and hold the recessed test switch with a 0.18
inch maximum diameter tool such as an allen wrench
or small screwdriver.
Notify the proper authorities the system is back on line.
Maintenance
NOTE: Before removing the detector, notify the proper
authorities that the smoke detector system is un-
dergoing maintenance and will temporarily be out
of service. Disable the zone or system undergoing
maintenance to prevent unwanted alarms.
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

NOTE: (Model 2100TD only) Before removing the de-
tector cover, note the position of the thermistors.
Make sure the thermistors are not bent over when
the housing is replaced.
Gently press the housing until it locks in place. Check
to make sure that the thermistors are in the upright po-
sition (2100TD).
9. Reinstall the detector.
1. Remove detector housing by gently prying the four hous- 10. Notify the proper authorities the system is back in op-
ing tabs on the bottom of the base with a small-bladed
screwdriver and pull the housing from the base. Use cau-
tion to avoid damaging the thermistors (2100TD only).

WARNING
The Limitations of Property Protection Smoke Detectors
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.
Smoke detectors will not work without power. AC or DC powered
smoke detectors will not work if the power supply is cut off.
pability but they are somewhat better at detecting fast flaming fires than
slow smoldering fires. Photoelectric detectors sense smoldering fires bet-
ter than flaming fires which have little, if any, visible smoke. Because fires
develop 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.
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.
In general, detectors cannot be expected to provide warnings for fires
resulting from inadequate fire protection practices, violent explosions,
escaping 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
dilution of smoke densities created by frequent and rapid air exchanges.
Additionally, 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 represent-
ative. 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.
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 ca-
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 obliga-
tion 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
workmanship under normal use and service during the three year period
commencing 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
Department, 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,
modifications, or alterations occurring after the date of manufacture. In no
case shall the Company be liable for any consequential or incidental dam-
ages for breach of this or any other Warranty, expressed or implied what-
soever, 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 consequential 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.
