Before you begin:
Read Avoid These Locations in this document for placement recommendations.
Step 1: Attach the included Mounting Bracket to the ceiling (or wall).
1. Remove the mounting bracket from the Smoke Sensor base by holding the Smoke
Sensor and twisting the mounting bracket clockwise (right). (Set the unit aside where
it won’t get covered with dust when you drill mounting holes later.)
2. Hold the mounting bracket against the ceiling (or wall) and mark the center of each of
the mounting slots with a pencil.

5. Tighten the included screws into the screw anchors.
Step 2: Activate the included battery.
Your Smoke Sensor ships to you with the battery in backwards to prevent the sensor from
alarming during transit. To activate the battery:
1. Open the Battery Compartment of the Smoke Sensor.
2. Re-insert the battery so its terminals match the terminals on the Smoke Sensor:
match “+” to “+” and “-” to “-”. Push the battery in until it snaps in securely. (Note

3. Close the Battery Compartment.
Step 3: Attach the Smoke Sensor to the mounting bracket.
Position the base of the Smoke Sensor over the mounting bracket and turn clockwise
(right) until the unit is in place.
Do not paint over the Smoke Sensor. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.
Step 4: Test your Smoke Sensor
See Test Your Smoke Sensor in this document for instructions.

Step 5: Connect your Smoke Sensor to Room Alert.
Do not connect the switch sensor inputs (dry contacts) on AVTECH products to any live
circuit.
Use only low-voltage 2-wire cable to connect switch sensor inputs.
Your Smoke Sensor comes with one end of the 25' speaker cable
already attached. Follow these steps to attach the other end to a
switch port on your Room Alert:
1. Separate and strip the leads on the free end of the speaker

open switch port on your Room Alert. Be sure the bare wire, not the
insulation, connects to the port. The leads are non-polarized, so you
may connect either lead to either side of the open port.
Avoid These Locations
• Over an electrical junction box
Do not install this unit over an electrical junction box. Air currents around junction
boxes can prevent smoke from reaching the sensing chamber and prevent the unit
from alarming.
• Where combustion particles are produced
Combustion particles form when something burns. Areas to avoid include poorly
ventilated kitchens, garages and furnace rooms.
Keep the Smoke Sensor at least 20 feet (6 meters) from the sources of combustion
particles (stove, furnace, water heater, space heater) if possible. In areas where
this distance is not possible, place the Smoke Sensor as far from these fuel-burning
sources as possible.
The placement recommendations are intended to keep the Smoke Sensor at a
reasonable distance from a fuel-burning source, reducing “unwanted” alarms.
• In air streams near kitchens
Air currents can draw cooking smoke into the sensing chamber of a Smoke Sensor
near the kitchen.

Page 4
Smoke Sensor (RMA-SS1-SEN)
• In very damp, humid or steamy areas, or directly near bathrooms with
showers
Keep units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the temperatures are regularly below 40° F (4.4° C) or above 100° F
(37.8° C)
• In very dusty, dirty or greasy areas
Do not install a Smoke Sensor directly over the stove or range. Keep laundry room
Smoke Sensors free of dust or lint.
• Near fresh air vents, ceiling fans or in very drafty areas
Drafts can blow smoke away from the unit, preventing it from reaching the sensing
chamber.
• In insect infested areas
Insects can clog openings to the sensing chamber and cause unwanted alarms.
• Less than 12 inches (305 mm) away from uorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces.
“Dead air” spaces may prevent smoke from reaching the Smoke Sensor. To avoid dead
air spaces:
On ceilings, install Smoke Sensors as close to the center of the ceiling as possible.

If the alarm does not sound during testing, try installing a new battery, and make sure it
is snapped in securely. If it still does not alarm, replace the sensor immediately.
If the Escape Light doesn’t light during testing, make sure the bulb is working properly. If
you suspect the bulb is burned out, it is not replaceable.
Clean your Smoke Sensor
Clean the Smoke Sensor at least once a month.
• You may gently vacuum the outside of the Smoke Sensor using your a vacuum’s soft
brush attachment or use a can of clean compressed air.
• Do not use water, cleaners or solvents as they may damage the unit.

Relocate your Smoke Sensor if necessary
Relocate the unit if it sounds frequent unwanted alarms. See Avoid These Locations in this
document for more information.
Replace the battery
When the battery becomes weak, the Smoke Sensor unit will “chirp” about once a minute,
which is the low battery warning. The low battery warning should last for 30 days, but you
should replace the battery immediately.
