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:

MODEL
Home Safeguard Industries
25S, 30S
SDi
CHEK02 and CHEK06
SDi
SOLOA4
SDi
SMOKESABRE-01
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.
CAUTION
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.
Remote Test
2251BR can be remotely tested using the RTS451, RTS451KEY, RTS151, or
RTS151KEY test accessories. Refer to the DNR/DNRW manual for wiring
diagrams. Maximum test response time may be up to two communica-
tions from the panel.
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.
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
detector system is undergoing maintenance and will be temporarily out of
service. Disable the zone or system undergoing maintenance to prevent un-
wanted 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.
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.
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.
