GB2461275A - Lighting directing people to a safe exit and activated by sound of smoke detector - Google Patents

Abstract

When a smoke detector sounds, a receiver transmitter will pick up the sound and transmit a signal to independent low-level lights. People can follow the low-level lights to a safe exit on an agreed route when on the floor. The lights may also have an audible sound. The lights can be of different colours to show landing areas, green, and stairs, red. The system does not involve any hard wiring can be added to an existing smoke detector.

The Illuminated Map Out System

Description

All houses should have a fire alarm system.

Most houses just have smoke detectors. These are normally situated on the ground or first floor.

Unfortunately when a fire starts smoke is the main cause of injury and death. People are unable to get out safely.

When smoke fills the house visibility is the first thing to go.

What we are told is when a fire starts to get down on our knees and crawl to safety.

But bow do we know where to go when we are in this panic state? Our idea is to have low lighting which will show us the way out.

All lighting is normally from the ceiling so when smoke fills the house, since smoke rises the light is blocked.

Our lights will encourage people to get to the floor and follow the lights, which also have an audible sound, to a safe exit point.

These lights can be placed by the family as an agreed exit route.

When the smoke detector (A) sounds, it will activate the receiver and transmitter (B). This will transmit a signal to switch on the lights (C). These lights will switch on to show a way out in a fire situation.

This is the basic principle of the operation.

B' is the receiver transmitter which will pick up the sound (decibels) of the existing smoke detector.

B' will transmit the signal to our lights C' which are all independent.

The lights C' will switch on and show direction to the agreed exit points.

Lights will emit sound and shall be of different colours to show landing areas and stairs i.e. Green for landing areas and red for stairs.

B' receiver transmitter will be of PCB and chip technology picking up veritable sound and transmitting frequency to receiver C' lights. It will also operate on battery power (ordinary or rechargeable) an* emit a low battery sound.

The receiver transmitter B' will be contained in a bracket which will be self adhesive or screwed allowing B' to be removed from the bracket for battery change or recharging.

C' is our low voltage lights which incorporate a receiver to pick up from B'.

This will switch on when the alarm goes off activating the light and sounder to help pinpoint direction.

These lights should be set out in an agreed exit route.

Colour change of lights is available in order to allocate landing area and stairwells.

C' can be powered by battery or rechargeable battery. A reset button for test purposes and low battery sounder is also included.

C' operates on PCB and chip technology allowing fitting to be compact. Fixing bracket can be self adhesive or screwed to the wall so as C' can be clipped into and out of the bracket and removed for battery change or recharging.

The cosmetic design of the lights should include an element to appeal to children to encourage them to follow the path and limit their fear in a fire situation.

The principle of the product is that it can be installed by anyone as it does not involve any hard wiring.

This product should be available so it can be added to any existing smoke detectors to assist the safe evacuation of persons from a fire situation.

We recommend that receiver transmitter B' be situated beside an existing smoke detector.

Light fittings C' should be spaced 1.5 metres apart.

For every smoke detector the receiver transmitter B' should be fitted as this will make sure that there is no interference to the signal at the lights C'.
