on 3-1/2-inch and 4-inch octagonal box:
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 wir-
ing 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.

plug the terminal block into the detector.
2. Align the arrows on the detector with the arrows on the
mounting bracket.
Wiring Installation Guidelines
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 the following para-
graph.
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
6. Reset the detector at the system control panel.
7. Notify the proper authorities the system is in operation.

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.
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.
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 (Model 2100T 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 mainte-
nance and will temporarily be 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 2100 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 0.1 inch
maximum diameter tool such as an allen wrench or
small screwdriver.
Notify the proper authorities the system is back on line.
3. The detector’s LED should light within 5 seconds.

on the base with their counterparts on the housing. Gen-
tly press the housing until it locks in place. Check to
make sure that the thermistors are in the upright posi-
tion (2100T).
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.
7. Reinstall the detector.

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.
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.
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.
Smoke detectors cannot last forever. Smoke detectors contain electronic
parts. Even though smoke detectors are made to last over 10 years, any
part can fail at any time. Therefore, smoke detectors shall be replaced after
being in service for 10 years. The smoke detector system that this detector
is used in must be tested regularly per NFPA 72. This smoke detector
should be cleaned regularly per NFPA 72 or at least once a year.
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
