DESC:FIELD OF INVENTION:
The present invention relates to fire detector system. More particularly, the present invention relates to a tool to facilitate cleaning and servicing of fire detector system with ease. The present invention further relates to a method of cleaning and servicing of fire detector system using the said tool.

BACKGROUND AND PRIOR ART:
Fire detectors or smoke detectors are usually located on or inside the false ceiling. It is difficult to reach out to the detectors which are installed at a height or inside the false ceiling located at the top of actual ceiling.

Conventionally, said fire detector or smoke detector sensor is manually removed for cleaning and servicing and later fitted back. Thus, in places where false ceiling height is more and in places where the smoke detectors are installed inside the false ceiling, the manual approach becomes difficult.

Further, these detectors need to be cleaned regularly, otherwise, the system may give false alarm. Since, cleaning and servicing of smoke detector sensorsare done manually,it makes it difficult to access the detectors which are not approachable easily.

Thus, there is a need of a service tool to easily detach the detectors for cleaning and servicing and then placing it back again. The present invention thus discloses a tool to facilitate cleaning and servicing of fire detector system with ease.

SUMMARY OF THE INVENTION:
It is an object of the present invention to provide a tool to facilitate detaching and attaching of the said detectors for cleaning and servicing.

It is another object of the present invention to provide a convenient, safe and time saving tool to facilitate cleaning and servicing of fire detector system with ease.

It is another object of the present invention to provide a tool to facilitate access to smoke detectors which are at height and difficult to access.

The fire detector service tool according to the present invention mainly comprises, a locking means with projections and an extendable shaft fastened to said locking mechanism. The said locking means provides locking arrangement for detector so that it can be easily removed and fitted again after cleaning and servicing.

Further, the said projections are same as that of the smoke detectors for easy locking.

The present invention further relates to a method of cleaning and servicing of fire detector system using the said tool.

DETAILED DESCRIPTION OF THE INVENTION
The invention is described herein in detail with the help of figures appended at the end of the specification. The figures illustrate the preferred embodiment as well as other embodiments that define the scope of the present invention. However, it may be understood that the figures presented herein are intended to exemplify the scope of the invention only. The person skilled in art may note that by no means the figures limit the scope of the invention. Any variation in the drawings by any other person will be falling in the scope of the present invention.

As illustrated in Figures 1-2, the tool (1) to facilitate access to smoke detectors mainly comprises, a locking means (2) and an extendable shaft (3) fastened to said locking mechanism (2).

The said a locking means (2) provides locking arrangement for detector so that it can be easily removed and fitted again after cleaning and servicing.

In a preferred embodiment according to the present invention, a service tool (1) to facilitate cleaning and servicing of fire detector system comprises, a locking means (2) having circular bar with projections (4); and an extendable shaft (3) fastened to said locking mechanism (2).

In a same preferred embodiment according to the present invention, said extendable shaft (3) is fastened to said locking means (2) using plurality of fastening members (6).

In a same preferred embodiment according to the present invention, said fastening members (6) are selected from nuts and bolts.

In a same preferred embodiment according to the present invention, said locking means (2) is selected from aluminium material.

In a same preferred embodiment according to the present invention, said extendable shaft (3) comprises knurling surface (5) on one end.

In a same preferred embodiment according to the present invention, a method of cleaning and servicing a fire detector system using service tool (1) comprises the step of,
placing the tool (1) against the fire detector assembly;
locking the tool (1) having locking means (2) with projections (4) on to the fire detector assembly;
detaching the fire detector assembly for cleaning, by turning the tool (1) in counter-clockwise direction using extendable shaft (3);
re-attaching the fire detector assembly after cleaning, by placing fire detector assembly on to the required location using the tool (1);
locking the fire detector assembly by, rotating the tool (1) in clockwise direction.

In a further preferred embodiment according to the present invention, said projections (4) are same as that of the smoke detectors for easy locking.

In an exemplary embodiment according to the present invention, said extendable shaft (3) is 1 meter long.

The advantages of the present invention include, ease of use, compact, light-weight, easy to carry, time saving and safe.

The foregoing descriptions are merely specific embodiments of the present invention, but are not intended to limit the protection scope of the present invention. Any variation or replacement readily figured out by a person skilled in the art within the technical scope disclosed in the present invention shall fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
