Detection system with addressable units
A detection system ( 10 ) for hazard detection is provided. The detection system ( 10 ) includes a control loop ( 16 ); an addressable base unit ( 18 ) connected to the control loop ( 16 ), the base unit ( 18 ) including a first near-field communication module ( 22 ) storing a unit address; and a mounting unit ( 20 ) removably coupled to the base unit ( 18 ), the mounting unit ( 20 ) including a second near-field communication module ( 24 ) operable to read the unit address from the first near-field communication module ( 22 ) and store the unit address so that the mounting unit ( 20 ) is thereby addressable via the control loop ( 16 ).
1. A detection system for hazard detection, comprising
a control loop;
an addressable base unit connected to the control loop, the base unit comprising a first near-field communication module storing a unit address; and
a mounting unit removably coupled to the base unit, the mounting unit comprising a second near-field communication module operable to read the unit address from the first near-field communication module and store the unit address so that the mounting unit is thereby addressable via the control loop;
wherein the second near-field communication module is operable to write to the first near-field communication module with a unit address, configuration information, unit health information, profile information, alarm information, sensor data and/or disablement information.
2. A system as claimed in claim 1 , wherein the first near-field communication module is removably attached to the rest of the base unit.
3. A system as claimed in claim 1 , wherein the second near-field communication module is integral to the mounting unit.
4. A system as claimed in claim 1 , comprising a mobile device, the mobile device comprising a third near-field communication module operable to write to the second near-field communication module and thereby configure the mounting unit for use.
5. A system as claimed in claim 1 , comprising a plurality of near-field communication modules each storing a different unit address, wherein at least one of the plurality of near-field communication modules is unattached to any other part of the system.
6. A system as claimed in claim 1 , wherein the mounting unit is configured to be powered wirelessly via the second near-field communication module and the first near-field communication module of the base unit.
7. A system as claimed in claim 1 , wherein at least one of a sensor, a processor, a memory, an audible indicator, or a visual indicator of the mounting unit is configured to be powered wirelessly via the second near-field communication module and the first near-field communication module of the base unit.
8. A system as claimed in claim 1 , wherein the base unit does not comprise electrical terminals for contact with the mounting unit.
9. A method of operating a detection system for hazard detection, the system comprising:
a control loop;
an addressable base unit connected to the control loop, the base unit comprising a first near-field communication module storing a unit address; and
a mounting unit removably coupled to the base unit, the mounting unit comprising a second near-field communication module;
the method comprising reading the unit address from the first near-field communication module using the second near-field communication module;
storing the unit address in the mounting unit so that the mounting unit is thereby addressable via the control loop; and
writing, using the second near-field communication module, to the first near-field communication module with configuration information, unit health information, profile information, alarm information, sensor data and/or disablement information.
10. A method as claimed in claim 9 , comprising selecting the first near-field communication module from a plurality of available near-field communication modules, each of the plurality of available near-field communication modules having stored therein a respective unit address.
11. A method as claimed in claim 9 , comprising using a mobile device comprising a third near-field communication module to read the unit address from the mounting unit and/or the base unit while the mounting unit is coupled to the base unit.
12. A method as claimed in claim 11 , comprising configuring the plurality of near-field communication modules remotely using the mobile device.
13. A method as claimed in claim 9 , wherein the mounting unit is a first mounting unit, the method comprising uncoupling the first mounting unit from the base unit, coupling a second mounting unit comprising a respective near-field communication module to the base unit, reading the unit address from the first near-field communication module using the respective near-field communication module of the second mounting unit; and storing the unit address in the second mounting unit so that the second mounting unit is thereby addressable via the control loop.
14. A method as claimed in claim 9 , comprising powering the mounting unit wirelessly via the first near-field communication module and the second near-field communication module.
