Abstract

A wireless damper control and test system comprising a wireless controller for communicating with a wireless interface using an identifier whereby actuation timing of a damper actuator is transmitted by signal, the wireless interface connected to a damper to be controlled or tested using the transmitted signal, the wireless controller transmits the signals to the wireless interface for operational verification of the damper and damper actuator, and the wireless interface detects a damper state by contacts mounted on the damper and communicates the damper state to the wireless controller.

First claim

We claim:

1. A method for controlling a damper comprising:
generating a radio frequency query signal from a handheld controller;
receiving a plurality of radio frequency response signals from a plurality of dampers in response to the radio frequency query signal;
generating a user-selectable display identifying the plurality of dampers based on the received plurality of radio frequency response signals;
receiving a user selection of one of the plurality of dampers;
transmitting a test control to the selected damper, wherein the test control is configured to activate a test circuit of the selected damper;
receiving a response from the selected damper, wherein the response is generated based on whether a reading has been received from a contact of the test circuit; and
generating a user display showing the response, wherein the response includes a pass or a fail message.

2. The method of claim 1 wherein the test control comprises a blade position test control.

3. The method of claim 1 wherein the test control comprises a switch contact test control.

4. The method of claim 1 wherein the test control comprises a smoke alarm test control.

5. The method of claim 1 wherein the test control comprises a relay position test control.

6. The method of claim 1 further comprising:
receiving the test control at the selected damper; and
activating a selected component in response to the test control.

7. The method of claim 1 further comprising:
receiving the test control at the selected damper; and
activating a relay in response to the test control.

8. The method of claim 1 further comprising:
receiving the test control at the selected damper;
activating a relay in response to the test control; and

determining whether the reading has been received from the contact.

9. The method of claim 1 further comprising:
receiving the test control at the selected damper;
activating a relay in response to the test control;
determining whether the reading has been received from the contact; and
generating the fail message if the reading has not been received.

10. The method of claim 1 further comprising:
receiving the test control at the selected damper;
activating a relay in response to the test control;
determining whether the reading has been received from the contact; and
generating the pass message if the reading has been received.

11. The method of claim 1 further comprising:
receiving the test control at the selected damper;
activating a smoke alarm test circuit in response to the test control;
determining whether the reading has been received from the smoke alarm test circuit; and
generating the fail message if the reading has not been received.

12. The method of claim 1 further comprising:
receiving the test control at the selected damper;
activating a smoke alarm test circuit in response to the test control;
determining whether the reading has been received from the smoke alarm test circuit; and
generating the pass message if the reading has been received.

13. The method of claim 1 , wherein receiving the user selection includes receiving a scan control for each of the plurality of dampers, and the method further comprising:
transmitting the test control to each of the plurality of dampers;
receiving the response from the each of the plurality of dampers; and
generating the user display showing the plurality of responses.

14. The method of claim 1 , wherein the reading comprises an indication from a contact switch configured to identify a blade position of the selected damper.

15. The method of claim 1 , wherein the test circuit is configured to test a position of a blade of the selected damper, wherein the position includes an open position, a closed position, or both.

16. A method for controlling a damper comprising:
generating a radio frequency query signal from a handheld controller;
receiving a plurality of radio frequency response signals from a plurality of dampers;
generating a user-selectable display identifying the plurality of dampers;
receiving a user selection of one of the plurality of dampers;
transmitting a test control to the selected damper;
receiving a response from the selected damper;
generating a user display showing the response;
receiving the test control at the selected damper;
activating a relay in response to the test control;
determining whether a reading has been received from one or more contacts in response to activating the relay;
generating a fail message if the reading has not been received; and
generating a pass message if the reading has been received;
wherein the test control comprises one or more of a blade position test control, a switch contact test control, a smoke alarm test control, and a relay position test control.

17. A method for testing a damper system, comprising:
transmitting, with a controller, a radio frequency query signal to a plurality of dampers within range of the controller;
receiving, with the controller, a radio frequency response signal from a damper of the plurality of dampers in response to the radio frequency query signal;
transmitting a test signal to the damper with the controller, wherein the test signal is configured to:
activate a test function of the damper, wherein the test function includes movement of a blade of the damper; and
generate a test response based on whether a reading from a contact switch is received by a test circuit of the damper, wherein the test response corresponds to an outcome of the test function, wherein the reading of the contact switch indicates a position of the blade of the damper;

receiving the test response with the controller; and
displaying a result of the test function based on the test response.

18. The method of claim 17 , wherein the result includes a pass indicator or a fail indicator.

19. The method of claim 17 , wherein the test function is configured to cycle movement of the blade of the damper to an open position and a closed position and to return the blade to an initial position.
