Wireless takeover of an alarm system
View Patent ↗The present invention extends to methods, systems, and computer program products for wireless takeover of wired alarm system components. Embodiments of the invention can be used to bridge hardwired alarm zones for use with a wireless alarm controller. Wired sensors are wired to a takeover module that converts communication from the wired sensors into wireless communication that can be compatibly processed at an alarm controller that accepts wireless signals. Power and ground connections from an existing wired alarm controller can be used with the takeover module to facilitate wireless takeover of wired alarm sensors.
1. An alarm system, comprising:
one or more alarm sensors, each alarm sensor of the one or more alarm sensors configured to couple to alarm hardware via one or more wires; and
a takeover module configured to couple to and receive sensor data from each alarm sensor independently of the alarm hardware, the takeover module comprising:
a processor configured to convert received sensor data into digital sensor data; and
a wireless transmitter configured to transmit the digital sensor data to an alarm controller.
2. The alarm system of claim 1 , the takeover module comprising one or more external connections configured to couple to the one or more alarm sensors via one or more wires.
3. The alarm system of claim 1 , the processor further configured to convert the received sensor data into a format that is compatible with the alarm controller.
4. The alarm system of claim 1 , the wireless transmitter configured to transmit the digital sensor data locally to the alarm controller.
5. The alarm system of claim 1 , the takeover module further configured to couple to a battery via a backup power connection.
6. The alarm system of claim 1 , the takeover module further configured to couple to a power output terminal of the alarm hardware.
7. A takeover circuit for taking over alarm system components at a monitored location, the takeover circuit comprising:
at least one connection for connecting to one or more sensors via one or more wires;
a controller configured to receive sensor input from the one or more sensors and consolidate the sensor input into a digital input data stream; and
a wireless transmitter configured to transmit the digital input data stream to a local alarm controller.
8. The takeover circuit of claim 7 , further comprising one or more electrical components for conditioning sensor input from the one or more sensors for subsequent processing.
9. The takeover circuit of claim 7 , the at least one connection for connecting to one or more alarm zones, each alarm zone including at least one sensor of the one or more sensors, the controller further configured to:
assign each alarm zone of the one or more alarm zones a serial number representative of a sensor of the one or more sensors; and
associate an assigned serial number for an alarm zone with sensor input received from at least one sensor of the one or more sensors in the alarm zone.
10. The takeover circuit of claim 9 , the controller configured to receive sensor input indicating an alarm condition in a corresponding alarm system zone; and
wherein the wireless transmitter is configured to transmit an indication of the alarm condition along with the assigned serial number for the alarm system zone to the alarm controller to simulate detection of the alarm condition by a wireless alarm sensor.
11. The takeover circuit of claim 7 , further comprising an electrical terminal for connecting to an AC power source via wired alarm hardware.
12. A method of operating an alarm system, the method comprising:
receiving sensor input from at least one sensor via one or more wired links;
converting the sensor input into a digital input data stream; and
wirelessly transmitting the digital input data stream to a local alarm controller.
13. The method of claim 12 , further comprising conditioning the sensor input from the at least one sensor for processing by a processor.
14. The method of claim 12 , further comprising:
monitoring a power level of a battery backup; and
sending a low battery indicator to a processor if the power level is approaching a level that would be insufficient to power the takeover circuit.
15. The method of claim 12 , the receiving sensor input from at least one sensor comprises receiving sensor input from one or more alarm zones, each alarm zone of the one or more alarm zones comprising a sensor of the at least one sensor.
16. The method of claim 15 , further comprising assigning each alarm zone of the one or more alarm zones a wireless sensor serial number representative of a wireless sensor prior to receiving sensor input from the one or more alarm zones.
17. A non-transitory computer-readable storage medium storing instructions that when executed by a processor cause the processor to perform instructions for operating an alarm system, the instructions comprising:
converting sensor input received at a takeover module via one or more wires into a digital input data stream; and
wirelessly transmitting the digital input data stream locally to an alarm controller.
18. An alarm system, comprising:
one or more sensors configured to independently couple to each of alarm hardware and a takeover module via one or more wires, the takeover module configured to:
convert data received from the one or more wires into digital sensor data; and
wirelessly transmit the digital sensor data; and
an alarm controller configured to receive digital sensor data wirelessly transmitted from the takeover module.
19. The alarm system of claim 18 , further comprising a processor for converting the digital sensor data into a format that is compatible with the alarm controller.
20. The alarm system of claim 19 , wherein one of the takeover module and the alarm controller comprises the processor.
