System Sensor warrants its enclosed product to be free from defects 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 the enclosed product.
No agent, representative, dealer, or employee of the Company has the authority to in-
crease or alter the obligations or limitations of this Warranty. The Company’s obligation
of this Warranty shall be limited to the replacement of any part of the product 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, Returns 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
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 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 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.

FCC STaTemenT
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used
in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installa-
tion. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help.

Using a 1000-1500 watt hair dryer, direct the heat toward either of the thermis-
tors. 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 detec-
tor 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 wiring and
provides visual status indication at each detector. Refer to System Sensor lit-
erature 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 num-
bers 2WTR-B and 2WTA-B.

NOTE: Before performing maintenance on the detector, notify the proper au-
thorities that maintenance is being performed and the system will be tem-
porarily out of service. Disable the zone or system undergoing maintenance
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 pres-
ent 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 chamber
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.
