Abstract

A life safety device includes a housing, a detector for detecting one or more conditions, and an actuatable mechanism coupled to the housing. The actuatable mechanism includes a light assembly operable in response to detection of at least one of the one or more conditions.

Claims (23)

1. A life safety device comprising:

a housing;

a detector for detecting one or more conditions, the one or more conditions including at least one smoke and carbon monoxide;

an actuatable mechanism movably coupled to the housing;

a light assembly including a first light source operable to transmit light at an exterior of the housing through the actuatable mechanism, the first light source being operable in response to detection of at least one of the one or more conditions; and

a second light source operable to transmit light at an exterior of the housing, the second light source being remote from the first light source, wherein the second light source is operable as an ambient light sensor.

2. The life safety device of claim 1 , wherein the light assembly is automatically operable in response to detection of an unacceptable level of smoke or carbon monoxide.

3. The life safety device of claim 1 , wherein the light assembly further comprises:

a cover; and

a light skirt for communicating light from the light source to the cover.

4. The life safety device of claim 3 , wherein the cover is generally flush with an exterior of the housing.

5. The life safety device of claim 3 , wherein the cover has at least one feature formed thereon to alter light the light emitted by the first light source.

6. The life safety device of claim 5 , wherein the at least one feature includes a plurality of concentric rings to diffuse light emitted there through.

7. The life safety device of claim 3 , further comprising a light transmission device positioned within the housing, wherein the light assembly is nested within a hollow interior of the light transmission device.

8. The life safety device of claim 6 , wherein a shape of the light skirt is generally complementary to the light transmission device.

9. The life safety device of claim 6 , wherein further comprising a light blocking material positioned adjacent the light transmission device.

10. The life safety device of claim 3 , wherein the cover includes at least one of tinting and printed text.

11. The life safety device of claim 1 , wherein the light assembly is an egress light having a brightness sufficient to illuminate an adjacent pathway or exit.

12. The life safety device of claim 1 , wherein actuation of the actuatable mechanism is configured to perform an operation associated with the life safety device.

13. The life safety device of claim 12 , wherein actuation of the actuatable mechanism initiates a test operation.

14. The life safety device of claim 12 wherein actuation of the actuatable mechanism performs a hush operation.

15. The life safety device of claim 12 , wherein actuation of the actuatable mechanism enrolls the life safety device within a system, the life safety device being configured to communicate wirelessly.

16. The life safety device of claim 1 , wherein the housing includes a lower housing portion and the actuatable mechanism is arranged adjacent a center of the lower housing portion.
