Abstract

Devices, systems, and methods for self-testing event devices of a building alarm system are described herein. One self-test alarm system device having a self-testing capability includes a first independent power source connected to a detector module and a second independent power source connected to a self-test module.

Claims (33)

1 . A self-test alarm system device having a self-testing capability wherein the self-test alarm system device comprises:

a detector module;

a first independent power source connected to the detector module;

a self-test module, wherein the self-test module is configured to utilize a mechanism to generate an input relating to an event to test a sensing capability of the detector module; and

a second independent power source connected to the self-test module, wherein the second independent power source is a different type of power source from the first independent power source,

wherein the detector module, the first independent power source, the self-test module, and the second independent power source are all included in a single self-test alarm system device.

2 . The self-test alarm system device of claim 1 , wherein the second independent power source is directly electrically connected to a power loop.

3 . The self-test alarm system device of claim 2 , wherein the second independent power source is directly electrically connected to the self-test module.

4 . The self-test alarm system device of claim 1 , wherein the second independent power source is directly electrically connected to the self-test module.

5 . The self-test alarm system device of claim 1 , wherein the second independent power source receives a trickle charge from a power loop.

6 . The self-test alarm system device of claim 1 , wherein the self-test alarm system device further includes a controller directly electrically connected to a power loop.

7 . The self-test alarm system device of claim 1 , wherein the self-test alarm system device further includes a charger directly electrically connected to a power loop.

8 . The self-test alarm system device of claim 7 , wherein the charger is directly electrically connected to the second independent power source and provides power from the power loop to the second independent power source.

9 . A self-test alarm system device having a self-testing capability wherein the self-test alarm system device comprises:

a detector module;

a first independent power source connected to the detector module;

a self-test module, wherein the self-test module is configured to utilize a mechanism to generate an input relating to an event to test a sensing capability of the detector module; and

a second independent power source connected to the self-test module, wherein the second independent power source is electrically connected between the self-test module and a controller and is a different type of power source from the first independent power source,

wherein the detector module, the first independent power source, the self-test module, and the second independent power source are all included in a single self-test alarm system device.

10 . The self-test alarm system device of claim 9 , wherein the controller is directly electrically connected to the second independent power source.

11 . The self-test alarm system device of claim 9 , wherein the controller is directly electrically connected to a power loop.

12 . A self-test alarm system device having a self-testing capability wherein the self-test alarm system device comprises:

a detector module;

a first independent power source connected to a self-test module and to a controller for controlling the self-test module, wherein the self-test module is configured to utilize a mechanism to generate an input relating to an event to test a sensing capability of the detector module, and wherein the first independent power source is not connected to a power supply; and

a second independent power source connected to the detector module, wherein the second independent power source is a different type of power source from the first independent power source,

wherein the detector module, the first independent power source, the self-test module, and the second independent power source are all included in a single self-test alarm system device.

13 . The self-test alarm system device of claim 12 , wherein the first independent power source is electrically connected between the self-test module and the controller.

14 . The self-test alarm system device of claim 12 , wherein the second independent power source is electrically connected to a controller.

15 . The self-test alarm system device of claim 12 , wherein the detector module is a battery powered, wireless, detector module.

16 . The self-test alarm system device of claim 12 , wherein the first independent power source is further electrically connected to a detector module.

17 . The self-test alarm system device of claim 12 , wherein the second independent power source is electrically connected to a controller different from the controller connected to the first independent power source.

18 . The self-test alarm system device of claim 12 , wherein the first independent power source connected to the self-test module is a battery power source.

19 . The self-test alarm system device of claim 12 , wherein the first independent power source is electrically connected between the controller and the self-test module.
