2. APPLICATION
The radio smoke detector is intended for the detection of smoke in interiors by the
use of optical and acoustic warnings, as well as wireless transmission over
distances of up to 30 meters. Range may vary due to battery and temperature
conditions. The SD833 smoke detector does not sense gas, heat or smokeless
flames! The equipment may not be modified under any circumstances.
3. POSITIONING
It is advisable to install several smoke detectors in your home. At least one smoke
detector should be installed on each floor. This ensures that an effective warning is
possible when a fire starts. One smoke detector must be installed in the area
outside the bedroom which is used as the exit (corridor and/or staircase). Also
ensure that you install the smoke detector at a location where it can be easily
heard, even through the closed door of the bedroom! (Otherwise you will not wake
up during a fire alarm!). Recommended best and acceptable locations to mount
smoke detectors (figure A):
The smoke detector should be installed on the ceiling in the centre of the room.
Smoke rises and gathers in this area (figure B) and placing the smoke alarm here
guarantees the earliest possible alarm warning. For sloping roofs, the smoke alarm
should be installed about 1 meter from the highest point, as displayed in figure C.
Smoke detectors can be installed in all rooms, but not in the bathroom or directly
above the cooking area in the kitchen. To avoid false alarms, do not install the
SD833 smoke detector in your kitchen, garage, in dusty places, in places with a
higher than average air flow (near ventilation, open windows), near metal and in
places where the temperature is below 5°C or above 37°C. Ensure that the smoke
detector is not installed directly on or near large metal objects as they can affect
the radio range. Before installing the SD833 smoke detector on your ceiling or the
wall, ensure that the SD833 is within range of your Marmitek security system. You
can test this by pushing the test button of the SD833. The Marmitek security
system should now be triggered, depending on the settings. In the case of range
problems, choose a different location for your SD833 smoke detector. Moving the
SD833 just a few centimetres can make a big difference in range.
