TAMPER RESISTANCE
W-SD355 and W-SD355T include a tamper-resistant capability that prevents
their removal from the base without the use of a tool. Refer to the base man-
ual for details on making use of this capability. The base also includes a mag-
net for tamper resistance. The magnet activates a supervisory tamper fault at
the panel if the detector is removed from the base.
TESTING
Before testing, notify the proper authorities that the system is undergoing
maintenance, and will temporarily be out of service. Disable the system to
prevent unwanted alarms.
All sensors must be tested after installation and periodically thereafter. Testing
methods must satisfy the Authority Having Jurisdiction (AHJ). Sensors offer max-
imum performance when tested and maintained in compliance with NFPA 72.
The sensor can be tested in the following ways:
A.
Functional: Magnet Test (P/N M02-04-01 or M02-09-00)
This sensor can be functionally tested with a test magnet. The test mag-
net electronically simulates smoke in the sensing chamber, as well as
tests the sensor electronics and connections to the control panel.
1. Hold the test magnet in the magnet test area as shown in Figure 4.
2. The sensor should alarm the panel.
Two LEDs on the sensor are controlled by the panel to indicate sensor
status. Coded signals, transmitted from the panel, can cause the LEDs
to blink, latch on, or latch off. Refer to the control panel technical docu-
mentation for sensor LED status operation and expected delay to alarm.
B.
Smoke Entry
The GEMINI model 501 aerosol generator can be used for smoke entry
testing. Set the generator to represent 4%/ft to 5%/ft obscuration as de-
scribed in the GEMINI 501 manual. Using the bowl shaped applicator,
apply aerosol until the panel alarms.
Additionally, canned aerosol simulated smoke (canned smoke agent)
may be used for smoke entry testing of the smoke detector. Tested and
approved aerosol smoke products are:
FL-400-004
MANUFACTURER
Home Safeguard Industries

SDi
When used properly, the canned smoke agent will cause the smoke detector
to go into alarm. Refer to the manufacturer's published instructions for proper
use of the canned smoke agent.
C2015-00
Canned aerosol simulated smoke (canned smoke agent) formulas will vary by
manufacturer. Misuse or overuse of these products may have long term ad-
verse effects on the smoke detector. Consult the canned smoke agent manufac-
turer's published instructions for any further warnings or caution statements.
C.
Direct Heat Method (Hair dryer of 1000-1500 watts).
A hair dryer of 1000-1500 watts should be used to test the thermistors. Di-
rect the heat toward either of the two thermistors, holding the heat source
approximately 12 inches from the detector in order to avoid damaging
the plastic housing. The detector will reset only after it has had sufficient
time to cool. Make sure both thermistors are tested individually.
A sensor that fails any of these tests should be cleaned as described under
CLEANING, and retested. If the sensor fails after cleaning, it must be replaced
and returned for repair.
When testing is complete, restore the system to normal operation and notify
the proper authorities that the system is back in operation.
CLEANING
Before removing the detector, notify the proper authorities that the smoke de-
C1092-00
tector system is undergoing maintenance and will be temporarily out of service.
Disable the zone or system undergoing maintenance to prevent unwanted alarms.
1.
Remove the sensor to be cleaned from the system.
2.
Remove the sensor cover by pressing firmly on each of the four removal
tabs that hold the cover in place. (refer to Figure 5).
3.
Vacuum the screen carefully without removing it. If further cleaning is
required continue with Step 4, otherwise skip to Step 7.
4.
Remove the chamber cover/screen assembly by pulling it straight out.
5.
Use a vacuum cleaner or compressed air to remove dust and debris from
the sensing chamber.
6.
Reinstall the chamber cover/screen assembly by sliding the edge over the
sensing chamber. Turn until it is firmly in place.
7.
Replace the cover using the LEDs to align the cover and then gently
pushing it until it locks into place. Make sure that the thermistors do not
become bent under the cover on the W-SD355T.
8.
Reinstall the detector.
9.
Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back on line.
SPECIAL NOTE REGARDING SMOKE DETECTOR GUARDS
Smoke detectors are not to be used with detector guards unless the combina-
tion has been evaluated and found suitable for that purpose.
