Abstract

A bulb 8 attached to a wire 12 is attached to a ceiling rose 4. The bulb 8 operates as normal via a switch. If there is a fire, smoke fumes rise and pass though vent 6 at the bottom of the rose, setting off the alarm 2. The alarm has a separate continuous mains power supply. The alarm 2 including the rose 4 the wire 12 and the bulb 8 are attached to the ceiling 10 by two screws 14.

Description

IMPROVEMENTS TO ALARMS This invention relates to alarms and in particular fire alarms and their position.
Household fire alarms are generally battery operated and fitted to ceilings. Very often the batteries run flat or are put in the wrong way round. If a mains supply is use to operate the said alarms this could be initially costly because extra wires will need to be fitted. It would be beneficial to have an alarm run by the mains supply without extra wires that could be installed by a confident DIY person.
It is an object of the invention to provide an improved fire alarm arrangement.
According to the present invention there is provided a fire alarm positioned in, or part of a ceiling rose or light fitting, including fluorescent lighting. The said alarm gets its constant power supply from the light ring main that runs to the said rose or light fitting that the alarm is in, or part of A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which : Figure 1 shows a bulb attached to a wire the wire is attached to a rose. At the bottom of the rose there is a vent. Inside and attached to the rose there is a fire alarm attached to the ceiling by screws.
Referring to the drawing figure 1 shows a bulb (8) attached to a wire (12) the wire (12) is attached to a ceiling rose (4) the bulb (8) operates as normal via a switch. (Not shown) If there was a fire the smoke fumes (not shown) would rise, some of which would pass though the vent (6) at the bottom of the rose, (4) setting of the alarm. (2) The alarm (2) has a separate constant power supply (not shown) at the rose, (4) compered to the bulbs power supply, which has a switch. (Not shown) Otherwise the alarm (2) would only have a power supply when the bulb (8) was switch on. The alarm (2) including the rose, (4) the wire, (12) and the bulb (8) are attached to the ceiling (10) by two screws. (14) It will be appreciated that the described system can be applied to any type of light fitting.
The fire alarm gets its constant power supply from the light ring main that runs to the light fitting. Apart from this constant power supply there is also another power supply that is controlled by a switch. This is to turn the light on and of.
The only way the alarm would not receive a source of electricity is if a fuse was blown or there was a power cut.
If a lower voltage alarm is used a transformer will be needed. This can also be positioned in the light fitting.
This invention is ideal for newly built homes were instead of fitting light fittings and fire alarms separately one unit can be fitted to do the two jobs.
Thus in accordance with the invention, there is provided a fire alarm positioned in, or part of a ceiling rose as preferred, or in any type of light fitting. The said alarm being powered by the mains supply.

Claims (8)

  1. CLAIMS 1. A fire alarm positioned in, or part of a ceiling rose or light fitting, including fluorescent lighting. The said alarm gets its constant power supply from the light
    ring main that runs to the said ceiling rose or light fitting that the alarm is in, or part of
  2. 2. A fire alarm as claimed in claim I wherein if a lower voltage alarm is used there will be a transformer this can be positioned in the ceiling rose or light fitting along with the alarm.
  3. 3. A fire alarm as claimed in claim I and claim 2 wherein the light fitting containing the alarm will have a vent to allow smoke fumes to activate the alarm.
  4. 4. A fire alarm as claimed in any preceding claim wherein the light fitting containing the alarm having one or more light bulbs.
  5. 5. A fire alarm as claimed in any preceding claim wherein the light fitting containing the alarm having one or more Fluorescent tubes.
  6. 6. A fire alarm as claimed in any preceding claim wherein the light fitting containing the alarm having a constant power supply.
  7. 7. A fire alarm as claimed in any preceding claim wherein the light fitting containing the alarm being the preferred ceiling rose.
  8. 8. A fire alarm substantially as described herein with reference to figure 1 of the accompanying drawing.
