LINKING SMOKE DETECTORS USING AN INTERCONNECT-CABLE
You can link smoke detectors of the same type with a cable. To link them, do not use the earthing cable, but ensure you
have an extra cable placed inside your ceiling for this purpose. Preferably use a (harmonized) wire with a diameter of
1,5 or 2,5 mm2 (H05V-U / H07V-U). Follow the same safety standards for this interconnection cable as you would for
installation of mains power cables. The interconnect-cable will lead a high voltage from one smoke alarm to the next. It
relays the signal by using the 0/neutral cable and the interconnect cable. If you switched the 0 and phase cables during
installation the detectors will sound the alarm constantly. By using this link function all devices will give alarm when
one device detects smoke. You can connect a maximum of 12 devices and link-operation is guaranteed as long as all
devices are connected to the same end-group and no switches are part of the same group.

To ensure you know the smoke detectors are inactive in case of power failure, ensure a vital part of your lighting is
attached to the same power group. Please view national standards for proper installation procedure.
USE, TESTING AND MAINTENANCE:
Use: The smoke detectors is operational if the 230V mains power is connected, the 9V backup battery is placed
and the SA-240 is mounted to the ceiling. The SA-240 can only be attached to the ceiling plate if the backup battery
is placed. If the device is operational the green LED will continously light. The red LED will blink every 40 sec. to
indicate the backup battery is ok. Once smoke is detected, the alarm will sound. Once the smoke disappears, the
smoke alarm will stop automatically.
Test:
Hold the test key for at least 2 seconds. The operation is still correct if you hear 2 or three signal tones. Check the
smoke detectors weekly. In alarm status the smoke detector will generate about 85dB(A). Do not use candles, open
fire or cigarettes to test the smoke detector. Test the link-function by holding the test-button even longer. The other
detectors will now start beeping.
