Abstract

An alarm system 31 comprises a controller 33 that provides an interface between environmental detectors such as a smoke detector 35, a carbon monoxide detector 39 and a heat detector 43 with an intruder alarm system 47 having at least one intruder detector 49,51. The detectors are each arranged to provide an alarm output to the controller 33. Upon detection of a change in the physical environment by one of the environmental detectors a signal may be transmitted to other environmental detectors to activate their respective detector alarm output and to the controller 33 which sends a signal to the intruder alarm system 47 to activate the intruder alarm output 53 (see figure 5). The signal transmitted to the controller from one of the environmental detectors may be displayed on a user interface 57, such as a mobile phone, allowing the source, location, and type of change to be identified. Similarly, upon activation of an intruder detector 49,51, a signal is transmitted to the controller 33 which communicates and activates the alarm output of at least one of the environmental detectors 35,39,43 (see figure 6).

Description

Improved Alarm System
Introduction
The present invention relates to an alarm system and in particular an alarm system with enhanced functionality.
Backqround to the Invention io An alarm system as referred to herein is any type of electronic system used in a domestic or industrial premises which creates an alert in response to detection of a change in the physical environment. This could be the presence of smoke, heat, an excess of a gas such as carbon monoxide, or the presence of an intruder as detected by movement or the actuation of a switch.
A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag. Heat detectors have two main classifications of operation, "rate-of-rise" and "fixed temperature". The heat detector is used to help in the reduction of property damage.
A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas to prevent carbon monoxide poisoning. CO is a colourless, tasteless and odourless gas produced by incomplete combustion of carbon-containing materials. It is often referred to as the "silent killer" because it is virtually undetectable by humans. Elevated levels of CO can be dangerous to humans depending on the amount present and length of exposure. Smaller concentrations can be harmful over longer periods of time while increasing concentrations require diminishing exposure times to be harmful. smoke detector is a device that senses smoke, typically as an indicator of fire.
Smoke detectors are usually housed in plastic enclosures, typically shaped like a disk about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but shape and size vary. Smoke can be detected either optically (photoelectric) or by physical process (ionization). Detectors may use one or both sensing methods. Sensitive alarms can be used to detect and deter smoking in banned areas. Household smoke detectors, also known as smoke alarms, generally issue an audible or visual alarm from the detector itself.
In 2022, the Scottish government passed legislation which compelled every io household in Scotland to have interlinked fire alarms.
Every home must have: one smoke alarm in the living room or the room you use most; one smoke alarm in every hallway and landing; and one heat alarm in the kitchen.
All smoke and heat alarms should be mounted on the ceiling and be interlinked.
If there is a carbon fuelled appliance in the home, such as a boiler, fire, heater or flue a carbon monoxide detector must be located in that room.

Brief Description of the Drawings
The present invention will now be described with reference to the accompanying drawings in which: Figure 1 is a schematic diagram of a domestic dwelling which illustrates the position of various alarm devices in a premises; Figure 2 is a schematic diagram which shows an example of a system in accordance with the present invention; Figure 3 is a schematic diagram which shows an example of a controller in accordance with the present invention; Figure 4 is an example of a process in accordance with the present invention for connecting detectors to the controller of the present invention; Figure 5 is an example of a process in accordance with the present invention for using the system of the present invention where an environmental detector is activated; and Figure 6 is an example of a process in accordance with the present invention for using the system of the present invention where an intruder detector is activated.
Detailed Description of the Drawings
The present invention as exemplified below is, in one aspect, an alarm system which includes environmental detectors such as heat, fire and CO detectors. As well as the normal function of such detectors, which transmit an alert, such as a sound or a signal to other local detectors, each has an output to a controller which allows the identification of the detector.
In at least one embodiment, upon detection of a change to the physical environment by one of the environmental detectors, the environmental detector transmits a signal to the other environmental detectors to activate the detector alarm output and to the controller, wherein, the controller sends a signal to the intruder detector to activate the intruder detector alarm output.
The system may also be configured such that, upon detection of a change to the physical environment by one of the environmental detectors, the environmental detector transmits a signal to the controller wherein, the controller sends a signal to the user interface and the user interface identifies the environmental detector where the change to the physical environment has been detected.
Advantageously, this allows a user to identify the source and type of change, which typically could be excess heat, smoke or carbon monoxide and could be in one of several locations in a premises. Identification of the type and location of the problem is a significant enhancement of safety. I0
In at least one embodiment, the controller is also connected to an intruder detector which comprises one or more detection device such as a movement detector or a switch mounted on a door or window. Upon activation of the intruder detector, the intruder detector transmits a signal to the controller, wherein the RF output of the controller activates the alarm output of at least one of the environmental detectors.
Figure 1 is a schematic diagram of a domestic dwelling which illustrates the position at which various alarm devices may be located in a premises.
The property 1 is shown to comprise several rooms or areas which are room 3, room 5, room 7, room 9 and room 11. The arrangement of detectors illustrates the fact that, for safety reasons and in some cases as a result of legislation, there is a requirement to have multiple detectors of multiple types in a property.
For example, heat detectors 17 are often installed in kitchens. In some cases, as with this example, a kitchen may also have a smoke detector 12, but often the smoke detectors 12 are located outside the kitchen so as to ensure that normal kitchen fumes do not routinely set off the detector.
A heat detector will typically use the 433MHz wireless protocol, be wired or fitted with a 10 years battery, a test and hush button, end of life indicator Life and a siren which operates >85d3/M. The alarm will be set off at a temperature: 57°C/137F or an 8-15°C/Min rate of rise.
The smoke alarm and Carbon monoxide detector will have similar specifications to the heat detector in terms of battery life and wireless output.
Carbon monoxide detectors 15 are usually located in rooms where a fossil fuel fire such as an open fire or gas fire is located and beside a gas central hearing boiler.
