Alecto SA-50 Smoke Detector
RECOMMENDED INSTALLATION LOCATIONS FOR THE SA50
- Install the first smoke detector near the bedroom. Ensure that it is placed so, if it would detect fire, at least one exit route would still be accessible. We recommend placing one alarm near each potential blockade of your exit route, so you are alerted before a fire would block off your escape.
- Use multiple smoke detectors to increase safety and ensure an alert before the escape route is blocked.
- Install at least one smoke detector on each floor of your house.
- Install at least one smoke detector in each room where people smoke or where there is equipment that may potentially cause a fire.
- Smoke and heat will first move upwards towards the ceiling; after that the smoke and heat will travel horizontally.
- Install the detector on the ceiling. Except for rooms smaller than 1m, you should stay at least 50 cm away from the wall and 60cm from any corner. Smoke and heat do not gather in such corners, preventing the detector from alerting you on time.
DO NOT INSTALL IN THE FOLLOWING LOCATIONS:
- The kitchen; Steam from cooking might give a false alarm.
- The shower or bathroom; water damping might cause a false alarm and the moist environment might damage the detector.
- The garage: The car exhaust might cause a false alarm.
- In front of a fan or nearby the exhaust of an air conditioner or heater.
- In a ceiling nook.
- In rooms where the temperature could reach below 0°C or beyond 40°C.
- Do not paint or otherwise cover this smoke detector.
IMPORTANT: For optimal operation, we recommend mounting the smoke detector on the ceiling. See also the installation instructions. If ceiling mounting is not possible, we recommend that you place the smoke detector in the middle of a wall. The installation location must be in the natural airflow of the room and free of side walls or slope.
INSTALLATION INFORMATION:
Use the plugs or the supplied 3M double-sided tape to attach the base plate to
the ceiling.
If you want to attach it with screws, place the mounting plate at the desired
installation location and mark where the holes need to be drilled. Drill two
holes with a diameter of 5 millimeters. Push the plastic plugs into the holes.
Insert the screws into the mounting bracket and screw them firmly into the
dowels. Place the smoke detector on the mounting plate and secure by turning
clockwise.
USING, TESTING AND MAINTENANCE:
Normal condition:
When the smoke detector is in normal operation, the LED will light briefly
approximately every 40 seconds. The moment the detector enters the smoke or
fumes, the alarm will sound. When the smoke or fumes disappear, the alarm will
automatically stop.
Alarm:
When the smoke concentration reaches the alarm point and the smoke detector
detects smoke, the red indicator LED will flash and a loud alarm tone will be
heard. In alarm status, the smoke detector generates at least 85dB(A) sound
pressure. You can temporarily interrupt the alarm signal by pressing the test
button. If the smoke concentration is still too high after about 9 minutes,
the alarm signal will be heard again. Please always check your house in case
of an alarm to exclude fire.
Testing:
It is recommended that you test the smoke detector every week. If you briefly
press the test button, the red LED indicator will flash sequentially and
signal tones will sound. These signal tones will stop automatically. Do not
test the Smoke Alarm with candles, open flames, cigarettes or similar.
Low battery voltage:
If the battery voltage is too low, your smoke alarm’s red LED indicator will
flash once every 40 seconds and at the same time the alarm will beep once.
ATTENTION:
- If the cause of an alarm is unclear, assume it’s caused by fire. Immediately evacuate the building.
- Keep the smoke detectors out of range of children.
- Protect against dust during renovations. Without protection, the smoke detectors will lose their functionality.
Maintenance:
The smoke detector is maintenance-free. In very dusty rooms they may be
cleaned by vacuum.
PLAN AN ESCAPE ROUTE
- Make a map and mark all locations of doors and windows and a possible escape route. Note that you may need an escape ladder on high floors.
- Ensure everyone in the house knows the sound the smoke alarms produce and regularly practice use of the escape route.
- Leave the house immediately according to the plan when hearing the alarm. Every second counts: so respond quickly. If you do not notice smoke or heat, check if everyone in the house is in a secure location.
- Do not open any doors without feeling whether the door is warm or if there is smoke coming from underneath the doors. If it is, do not open that door. If the door is cold, put your shoulder firmly against the door and open it a small amount to check for any heat or smoke first.
- If there is much smoke, keep low and take shallow breaths, preferably through a moist towel. Call the fire department as soon as you are safe outside.
BATTERIES:
The detector is supplied using a lithium battery. Under normal conditions, the
battery will last at least ten years. If the detector is about to need
replacement, the smoke detector will make a beep sound every 40 seconds for at
least 30 days. If the smoke detector does not function, please contact your
supplier.
- To replace the battery, detach the smoke alarm from the mounting bracket by twisting counterclockwise.
- Remove the battery, and then install a new battery, matching the correct polarity markings. Type battery: 1x DC 3V (CR123A)
- Mount the smoke detector onto the mounting bracket by twisting clockwise to lock the detector. And then test the alarm.
