Test the Trouble Contacts:
With detector in Maintenance Mode and
cover removed/hanging from tether:
1. Remove the detector head by twisting it
counter-clockwise. The trouble contacts will
change state, the yellow TROUBLE LED will
change to steady illumination, the green PILOT
LED will remain flashing.
2. Twist the detector head back into place, the
trouble contacts will change back, the yellow
and green LEDs will resume flashing alternately.
Replace the unit’s front cover and fully depress
the latch lever to verify proper unit and system
stand-by (or normal) mode.
Upon proper replacement of the unit’s front
cover, the Maintenance Mode will automatically
be cancelled and the RT-3000 will revert to
normal operational (stand-by) status where
failure to have the cover properly in place
and latched will immediately cause a trouble
condition.
Should additional testing also be required for
simulated fire conditions, smoke bombs placed
in the duct may not be suited for the particular
detector head (photoelectric or ionization)
selected and installed. Consult the smoke bomb
data for proper use and compatibility with
detector type.
The S65A ionization detector head (55000-
225) utilizes a radioactive source as its means
of detection and will detect smoke particles of
between .1 and 1 micron in size.
The S65A photoelectric detector head (55000-
328) operates on the principle of light scatter
and will detect smoke particles of between 1
and 10 microns in size.
When purchasing smoke bombs for additional
required functional testing, ensure smoke
particle sizes comply with the criteria as
described above.
NOTE:
In situations that require a duct smoke
detector to be held in an alarm condition for
an extended period of time, the magnet test or
smoke test methods should be used to ensure
the detector is locked into alarm.
Each installation location must be assessed on
its own merits. If the protected area is of a very
dirty nature then the RT-3000 duct unit(s) will
have to be checked and cleaned on a quarterly
basis or when cleaning is required.
As a guideline the smoke detector head should
be cleaned every six months or as required.
The best methods of cleaning are to vacuum
the detector head thoroughly or to blow the
detector head out using clean, dry compressed
air.
Do not use chemicals or non-conforming air to
clean the detector head housing as this could
contaminate the detector head and damage the
casing.
Sampling tubes must be inspected and cleaned
in accordance with the schedule as determined
above, to allow the free flow of air through both
inlet and exhaust tubes.
Consult your local code and AHJ requirements
for required maintenance schedules.
1. Press the black MAINTENANCE button on
the front cover to initiate the RT-3000’s 3-minute
Maintenance Mode.
- Pressing the MAINTENANCE button a
second time within 30 seconds will return the
detector to stand-by.
- Other than above, pressing the
MAINTENANCE button a second time while
in Maintenance Mode will reset the 3 minute
timer. The MAINTENANCE button can be
accessed directly from the unit’s control
board if the cover is not in place.
2. The green PILOT LED will flash while in
Maintenance Mode and the cover latched.
3. You are safe to perform test/maintenance
functions without extra reports to the system.

Magnet Test
1. Place the square (short-sided)
end of the magnet provided with
the installation kit on the grey
section of the housing, inline with
the area designated “Test Magnet”.
Allow at least five seconds for
alarm initiation.
2. Upon alarm initiation, both the detector head
LED and red ALARM LEDs will illuminate. Alarm
relays will change state and the alarm related
remote accessories, if attached, will function. The
green PILOT LED will continue to flash.
3. Remove magnet and reset the detector by
pressing the red TEST / RESET button on the
front cover.
Smoke Test
1. Using smoke canister with testing nozzle
(available from Air Products, part number
TG-2000), insert the test gas nozzle into the
patented test port on the unit cover.
2. Press can against cover to release gas into the
chamber.
CAUTiON
: DO NOT SPRAY GAS
FOR MORE THAN ½ SECOND. OVERUSE
OF TEST GAS FACILITY MAY RESULT IN
DETECTOR CONTAMINATION.
After 15 - 20 seconds the detector head will go
into alarm, illuminating both the detector head
LED and red ALARM LED on the control board.
Duct unit functions will operate, alarm relays
will change state, and the alarm related remote
accessories, if attached, will function.
3. Lift the cover latch and remove the cover.
4. Clear the smoke from the chamber
5. Press the TEST / RESET button on the control
board
6. The green PILOT and yellow TROUBLE LEDs
will flash alternately, indicating the unit is in
Maintenance Mode while the cover is not in
place.
Alternately, if no test gas is available to conduct
functional testing:
With detector in Maintenance Mode:
1. Lift the cover latch and remove the cover. The
green PILOT and yellow TROUBLE LEDs will
flash alternately.
2. Blow smoke from a cotton wick or punk
directly at the head to cause an alarm.
3. The alarm indicators described above should
illuminate within one minute. Duct unit functions
will operate, alarm relays will change state, and
the alarm related remote accessories, if attached,
will function.
4. Clear the smoke from the chamber
5. Press the TEST / RESET button on the control
board
6. The green PILOT and yellow TROUBLE LEDs
will flash alternately, indicating the unit is in
Maintenance Mode while the cover is not in
place.

IMPORTANT NOTE!
Cover Removal and Replacement
The RT-3000 cover seats firmly against a
high-performance rubber gasket. This gasket
is durable, requires no maintenance and will
provide the weathertight endurance that
outdoor enviornments will require over the
life of the unit.
To avoid accidental damage to the gasket:
When removing the cover from the unit, lift
the stainless steel cover latch to its upright
position and pull/lift uniformly on the corner
tabs for best leverage.
When replacing the cover, be sure the stainless
steel cover latch is in its upright position
before properly seating the cover straight
onto the base. Then fully depress the cover
latch.
