Definitions

  • the present invention relates to an alarm and particularly, but not exclusively, to an alarm for detecting radiation and/or air pollutants such as smoke, carbon monoxide, radon and the like.
  • an alarm for detecting radiation and/or air pollutants such as smoke, carbon monoxide or the like having:
  • the present invention also provides an alarm system for a building for detecting radiation and/or air pollutants such as smoke, carbon monoxide or the like, said system comprising:
  • each alarm being connectable in a lighting circuit
  • Figure 5 is a circuit diagram of a reset circuit for the alarm
  • Figure 9 is a circuit diagram of a sensitivity adjustment circuit for the alarm.
  • the housing 12 carrying a male bayonet fitting 14 at one axial end and a female bayonet fitting 16 at the other axial end.
  • the housing is generally circular in cross-section although any suitable shape of housing may of course be used.
  • the bayonet fittings, 14, 16 are shown axially aligned and whilst this is the preferred alignment it will be appreciated that the smoke alarm may have more than one female bayonet fitting 16 to accommodate several lights, in which case they would not be axially aligned with the male bayonet fitting 14 but would normally be equi-angularly spaced about the axis.
  • the bulb and the bayonet fitting may become relatively hot. It is common for the bayonet fitting in conventional lighting circuits to reach, or even exceed, temperatures of around 160°C. It is possible for the heat generated by the bulb and the bayonet fitting to be transmitted, either by convection or conduction, through the housing 12 and to the main circuitry 20.
  • Such heating of the main circuitry may compromise the efficiency or operation of the circuitry and this is particularly relevant to the rechargeable battery 24 which powers the circuitry. It can be shown that the life of such a rechargeable battery decreases as the battery temperature rises. It is essential, therefore, that the main circuitry, and particularly the battery, is prevented from becoming overheated due to the high temperatures of the bulb and the bayonet fitting.
  • the alarm 10 has a main housing 68 which, in this embodiment, has a cross-section being substantially elliptical and which houses the ionisation chamber 18 and the main circuitry 20 of the smoke alarm.
  • the housing 68 has a central aperture 70 which is of a greater diameter than the diameter of the tube 60.
  • the alarm 10 is arranged such that the main housing 68 surrounds the tube 60 with the tube extending through the centre of the aperture 70.
  • the housing 68 is spaced from, and connected to, the external surface of the tube 70 by means of one or more connecting legs 72, thereby providing an annular air gap 73 between the housing and the tube.
  • there are two connecting legs which are diametrically opposed across the aperture 70, although it will be appreciated that more than two legs can be used.
  • An end of the strip of non-conducting material projects out of the main housing of the alarm such that it can be pulled and withdrawn from between the buzzer and the circuit board prior to, or just after, insertion of the alarm into the ceiling rose light fitting.
  • the lighting circuitry can be switched on such that a trickle charge is provided to the battery as described earlier, thereby to charge to the battery.
