Flashes
Indication
Action
1
Unserviceable hardware fault
Rest unit and rerun sensitivity test.
If the error persists, replace the unit.
2-3
Detector is becoming sensitive
Clean the Unit. Reset the unit and rerun sensitivity test.
If the error persists, replace the unit.
4-7
Detector is within normal sensitivity range. N/A
8-9
Detector is becoming too sensitive
Verify that the smoke chamber is snapped down securely.
Clean the unit and replace the smoke chamber.
After the flashes, if the sensitivity is within limits and all other tests pass, the detector goes into alarm and
resets after 7 seconds.
If the sensitivity is not within limits, or an unserviceable hardware fault has been detected, the smoke detector LED
extinguishes until the detector is serviced.
Understanding the LED
The LED on the detector indicates the status of the detector as follows:
FLASHING
= Flashes every 8 seconds to indicate normal operation.
ON
= Detects smoke.
OFF
= Trouble or maintenance is required.
Understanding the Test/Silence Button
The Test/Silence button on the detector performs the following three functions:
Testing
= Press the Test/Silence button for 4 seconds. The detector performs a sensitivity test then sends a test
signal to the control panel.
Silence alarm
= Press to silence the sounder during an alarm. The sounder and alarm do not silence if smoke is still
present.
Silence trouble chirp
= Press to silence a trouble chirp. The trouble chirp resumes after 24 hours if the trouble
condition is not corrected.
Attaching and Removing the Detector
Attach the smoke detector to its mounting base as follows:
1. Line up the raised alignment tab on the lip of the smoke
detector with arrow on the mounting base. See Figure 4.
2. Insert the smoke detector into the base and turn clockwise
approximately 15 degrees. It should snap firmly into place.
To remove the detector from the mounting base, grasp the detector
and turn it counterclockwise approximately 15 degrees. The detector
should snap off of the mounting base. See Figure 5.
Installing or Replacing the Batteries
Observe polarity when installing the battery. Use only Panasonic Model
CR123A or DMP Model CR123-FIRE 3.0V lithium batteries.
When the batteries are low, the detector extinguishes its LED and chirps every 30 seconds until the batteries are
replaced. The sounder can be silenced for 24 hours by pushing the Test/Silence button. See Figure 1.
Note:
When setting up a wireless system, it is recommended to program zones and connect the receiver before
installing batteries in the transmitters.
1. Remove the detector from the mounting base. See
Attaching and Removing the Detector.
2. Slide the battery compartment cover away from the detector to unsnap it and lift it off. See Figure 3.
3. If replacing the batteries, remove the old batteries and dispose of them properly.
4. Observing correct polarity, insert two new 3V lithium batteries into the battery compartment and replace the
cover. Use only new batteries when replacing old ones.
5. Reattach the detector to the mounting base. See
Attaching and Removing the Detector.
6. Test the detector. See
Smoke Testing the Detector.
Caution:
Properly dispose of used batteries. Do not recharge, disassemble, heat above 212°F (100°C), or
incinerate. Risk of fire, explosion, and burns.
