Step 1. Insert the 4 “AAA” batteries into the battery compartment taking care that the connection respects
correct polarity showing on the battery holder.
Step 2. While the 4 batteries are inserted; the SD-7 will sound 2 short beeps and LED start flashing
Step 3. After 3 minutes, one short beep sounds indicating that it is starting to take the threshold reference value.
The process will be repeated every 100 sec and notified by a short beep respectively. The completion of
sampling process will be notified by a musical tune and the LED will be turned off, the SD-7 is now
ready for installation. Proceed to step 4.
However, after 20 minutes, if the SD-7 gives out continuous beeps instead, it indicates that the SD-7 is
rejecting this sampling process and its battery should be removed to silence the beeps. Then, start
from step 1 to try again after a pause at 30 seconds.
Step 4. Press the Test Button on the Smoke Detector, the LED will be on for 2 Sec. and the buzzer will sound a
2-tone beep to indicate the Smoke Detector is functioning normally and a radio signal is successfully
transmitted.
Step 5. Using the bracket as a template, drill two holes in the exact location, the
device is to be mounted and insert the dowels.
Step 6. Screw the bracket on with the two hooks facing down by using the screws
and screwing them into the dowels.
Step 7. Locate the single line mark on the detector and line it up with one of the
hook of the bracket. After both hooks fits in the two mounting holes on the
detector, rotate the detector counter-clockwise to lock it in onto the bracket.
The installation is now completed.
