What the Detector Cannot Do
The DET-RSMOKE is designed for use in a small family home or apartment, or small of-
fice. It has the following limitations that are shared by many optical smoke detectors:
The smoke detector cannot detect a fire if smoke cannot reach the sensor. Smoke from
fire inside walls or attics, on top of roofs, or in other floors may not reach a
detector quickly enough to cause an alarm in time for the occupants to escape
unharmed. In addition, if the detector is deliberately covered to prevent smoke
reaching it then it cannot detect smoke.
The alarm sounder may not be heard. If an occupant is in another room to the
detector, is hard of hearing, is asleep, or under the influence of drugs or alcohol,
then he or she may not hear the alarm and be able to react to it.
The detector may not be able to warn about smoke from fires caused by
carelessness and general safety hazards, such as: smoking in bed, violent
explosions, escaping gas, improper storage of flammable materials,
overloaded electrical circuits, children playing with matches or arson.
No smoke detector can detect every kind of fire. In particular, smoke from slow
smoldering fires rises slowly and may not reach the detector until flame breaks
out.
PHYSICAL INSTALLATION
Use the mounting plate as a template to mark and drill two screw holes in the position
where you wish to fit the detector (see Figure 10). Note the orientation pointers molded
into the mounting plate. The two pointers are at right angles to the position of the test but-
ton on the face of the detector.
