Alecto SA-31 Smoke Detectors for Domestic Environments
The SA-31 is a smoke detector set for discovery of fire in the first stage. If
smoke develops,
the SA-31 will give a loud beep of at least 85dB (A). As part of the link
function all the smoke alarms within range will sound the alarm. We advice to
test the smoke detectors weekly using the test button on the detectors. Save
this manual in a safe place or inside of the electricity meter cupboard.
RECOMMENDED INSTALLATION LOCATIONS FOR THE SA-31
- 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 to place one alarm near each potential blockade of your exit route, so you are alerted before a fire would block off 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 equip-ment 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 61cm 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 damp 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 -10°C or beyond 40°C.
- Do not paint or otherwise cover this smoke detector.
INSTALLATION INFORMATION
Attach the ceiling plate using the included plugs and screws to the ceiling on a location of choice. Wall mounting is not recommended for smoke detection. Put the 9V block battery and AA batteries in the smoke detector. Then put the detector to the ceiling plate and, twist clockwise to lock it in place. Perform a first test by holding the test key for two seconds. Also see the paragraph: “Testing”.
USING, REGISTERING, TESTING AND MAINTENANCE
Using: The smoke detector works if the 9V battery has been placed. To be able
to link wirelessly, the 3 AA batteries must be placed. Be mindful that the red
clip has twisted to the inner side when you place the batteries, or the
detector won’t lock into the ceiling plate.
The unit will only be able to lock into the ceiling plate if both battery
types are installed. Once smoke is detected, the alarm will sound and the
other detectors will be wirelessly triggered as well. One the smoke
disappears, the smoke alarm will stop automatically. For the wireless trigger
on alarm, you first have to register the smoke detectors. There is no limit to
the amount of smoke detectors that can be linked, although they do have
limited range. Each smoke detector also extends the range.
Registering: For the registration process you have to assign one smoke
detector to be a “Master”. The rest of the smoke detectors will function as
“Slave”. On the master unit, press the “LEARN” twice. After the first press the
LED will be red, after the second press it will be green. Now press “LEARN” on
each of the detectors you want to connect, but only once so the LED will be
red. Once the first detector stops the green light, the connection is complete.
Test the connection by holding “TEST” on any unit until the other detectors
give an alarm as well. If the detectors will be placed more than a few feet
from each other, it is recommended to register these before installing them to
the ceiling plate.
Test
Hold the test key for at least 2 seconds. The operation is still correct if
you hear 2 or three signal tones. If you hold the test key longer, the
registered smoke detectors will also give an alert.
Check the smoke detectors weekly. We recommend to check the link function
monthly as well. Do not use candles, open fire or cigarettes to test the smoke
detector.
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 rennovations. 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 wether 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.
Replacing the batteries: The detectors are supplied using a 9V block battery. Only use the recommended types: Mustang 9V 6F22; GoldPeak 9V 1604A, 1604S; Pair Deer 9V 6F22, 6LR61. Under normal conditions the battery will last at least one year. If it is about to need replacement, the smoke detector will make a chirping sound every 45 seconds for at least 30 days. For the link function, the AA batteries are used. If these must be replaced, the detector will give 2 or 3 chirp sounds every 60 seconds. Pay attention to the polarity when replacing batteries. Test the detector after every battery replacement. If the smoke detector does not function, please contact your supplier.
Environment: Do not throw away used batteries, but recycle them using your local chemical depot. Product may not be thrown out as normal waste, but must be recycled as electrical waste.
