1. Wire the mounting base screw terminals per Figure 3a or Figure 3b,
as applicable.
2. Place detector on the base and rotate clockwise. The detector will
drop into the base and lock into place with a “click”.
3. After all detectors have been installed, apply power to the alarm
control unit.
4. Test each detector as described in Testing.
5. Reset all the detectors at the alarm control unit.
6. Notify the proper authorities that the system is in operation.
CAUTION
Dust covers are an effective way to limit the entry of dust into
the smoke detector sensing chamber during construction. However, they
may not completely prevent airborne dust particles from entering the de-
tector. Therefore, System Sensor recommends the removal of detectors
before beginning construction or other dust producing activity. When re-
turning the system to service, be sure to remove the dust covers from any
detectors that were left in place during construction.
CAUTION
Smoke detectors are not to be used with detector guards unless the combi-
nation has been evaluated and found suitable for that purpose.
CAUTION
When using the RRS-MOD with model 2WTA-B, do not mix the 2WTA-B
with other model smoke detectors and dry contact closure devices, in-
cluding mechanical heat detectors, manual pull stations and waterflow
switches. Such mixing can cause a direct short on the auxiliary power
terminals, damaging the control panel’s internal circuitry and/or damage
devices connected to the initiating device circuit.
Testing
Detectors must be tested after installation and following maintenance.
NOTE:
Before testing, notify the proper authorities that maintenance is be-
ing performed and the system will be temporarily out of service. Disable the
zone or system undergoing maintenance to prevent any unwanted alarms.
Ensure proper wiring and power is applied.
After power up, allow 80 sec-
onds for the detector to stabilize before testing.
Test i
3
Series detectors as follows:
A. Test Switch
1. An opening for the recessed test switch is located on the detector
housing (See Figure 4).
2. Insert a small screwdriver or allen wrench (0.18˝ max.) into the test
switch opening; push and hold.
3. If the detector is within the listed sensitivity limits, the detector’s red
LED should light within one second.

B. Smoke Entry Test
Hold a smoldering punk stick or cotton wick at the side of the detector and
gently blow the smoke through the detector until it alarms.
C. Direct Heat Method
Using a 1000-1500 watt hair dryer, direct the heat toward either of the
thermistors. Hold the heat source about 12 inches from the detector to
avoid damage to the plastic.
NOTE:
For the above tests, the detector will reset only after the power
source has been momentarily interrupted. It is not necessary to reset the
model 4WITAR-B, when smoke is used to initiate the alarm.
When testing the 4WITAR-B model, pressing the test switch will result in a
non-latching local alarm that does not alarm at the control panel. Once the
test button is released, the unit will return to its standby condition. Only
the fixed-temperature heat sensor will cause the 4WITAR-B to initiate an
alarm at the panel.
If a detector fails any of the above test methods, its wiring should be
checked and it should be cleaned as outlined in the Maintenance section.
If the detector still fails, it should be replaced.
Notify the proper authorities when the system is back in service.
Loop Verification (models 2WTR-B and 2WTA-B only)
Loop verification is provided by the EZ Walk loop test feature. This feature
is for use with i
3
Series compatible control panels or the i
3
Series 2W-
MOD2 module only. The EZ Walk loop test verifies the initiating loop wir-
ing and provides visual status indication at each detector. Refer to System
Sensor literature for further information on the 2W-MOD2.
WARNING
The 2W-MOD2 has replaced the previous model number 2W-MOD. To
ensure proper EZ Walk Test capabilities, do not use the 2W-MOD with i
3
model numbers 2WTR-B and 2WTA-B.

Maintenance
NOTE:
Before performing maintenance on the detector, notify the proper
authorities that maintenance is being performed and the system will be
temporarily out of service. Disable the zone or system undergoing mainte-
nance to prevent any unwanted alarms. Power must be removed from the
detector before performing maintenance of any kind.
1. Remove the detector cover by turning counterclockwise. (See Figure 5.)
2. Vacuum the cover or use canned air to remove any dust or debris.
3. Remove the top half of the screen/sensing chamber by lifting straight
up (Figure 5).
4. Vacuum or use canned air to remove any dust or particles that are
present on both chamber halves.
5. Replace the top half of the screen/sensing chamber by aligning the
arrow on the screen/sensing chamber with the arrow on the housing.
Press down firmly until the screen/sensing chamber is fully seated.
6. Replace the detector cover by placing it over the screen/sensing cham-
ber and turning it clockwise until it snaps into place.
7. Reinstall the detector and test. (See the Testing section.)
8. Notify the proper authorities when the system is back in service.
