Abstract

Devices, systems, and methods for a lid of an aspirating smoke detector device are described herein. In some examples, one or more embodiments include an aspirating smoke detector device, comprising a plurality of light pipes, a cover including a plurality of apertures to interface with the plurality of light pipes, a housing including a housing inlet and a housing outlet, and a reversible lid connectable to the cover in a first lid orientation and a second lid orientation, where when the cover and the housing are in a first device orientation, the reversible lid is to connect to the cover in the first lid orientation and when the cover and the housing are in a second device orientation, the reversible lid is to connect to the cover in the second lid orientation.

First claim

What is claimed:

1 . An aspirating smoke detector device, comprising:
a plurality of light pipes; a cover including a plurality of apertures to interface with the plurality of light pipes; a housing including a housing inlet and a housing outlet; and a reversible lid connectable to the cover in a first lid orientation and a second lid orientation, the reversible lid including a translucent portion and a plurality of symbols; wherein:
when the cover and the housing are in a first device orientation, the reversible lid is configured to connect to the cover in the first lid orientation; and
when the cover and the housing are in a second device orientation, the reversible lid is configured to connect to the cover in the second lid orientation.

2 . The aspirating smoke detector device of claim 1 , wherein when the reversible lid is connected to the cover in the first lid orientation, the plurality of light pipes and the plurality of symbols are in a first orientation.

3 . The aspirating smoke detector device of claim 1 , wherein when the reversible lid is connected to the cover in the second lid orientation, the plurality of light pipes and the plurality of symbols are in a second orientation.

4 . The aspirating smoke detector device of claim 1 , wherein the plurality of symbols are positioned on the reversible lid such that the plurality of symbols are located substantially adjacent to light emitted from the plurality of light pipes and through the translucent portion.

5 . The aspirating smoke detector device of claim 1 , wherein the housing houses a printed circuit board (PCB) having a plurality of light emitting diodes (LEDs).

6 . The aspirating smoke detector device of claim 5 , wherein the plurality of light pipes are positioned over the plurality of LEDs such that light emitted by the plurality of LEDs is transmitted through the plurality of light pipes and through the translucent portion of the reversible lid.

7 . The aspirating smoke detector device of claim 1 , wherein:
the housing inlet of the housing is configured to be connected to an inlet pipe of an aspirating smoke detection system; and the housing outlet of the housing is configured to be connected to an outlet pipe of the aspirating smoke detection system.

8 . The aspirating smoke detector device of claim 1 , wherein the reversible lid is connectable to the cover via a retaining frame.

9 . The aspirating smoke detector device of claim 8 , wherein the retaining frame includes a snap clip to interface with the cover to retain the reversible lid to the cover.

10 . An aspirating smoke detector device, comprising:
a plurality of light pipes including:
a first set of light pipes arranged in a first pipe configuration; and
a second set of light pipes arranged in a second pipe configuration;
a cover including a plurality of apertures to interface with the plurality of light pipes; a housing including a housing inlet and a housing outlet; and a reversible lid connectable to the cover in a first lid orientation and a second lid orientation, the reversible lid including a translucent portion having a plurality of symbols including:
a first set of symbols arranged in a first symbol configuration such that the first set of symbols are located substantially adjacent to light emitted from the first set of light pipes; and
a second set of symbols arranged in a second symbol configuration such that the second set of symbols are located substantially adjacent to light emitted from the second set of light pipes;
wherein:
when the cover and the housing are in a first device orientation, the reversible lid is configured to connect to the cover in the first lid orientation; and
when the cover and the housing are in a second device orientation, the reversible lid is configured to connect to the cover in the second lid orientation.

11 . The aspirating smoke detector device of claim 10 , wherein when the reversible lid is connected to the cover in the first lid orientation:
the first set of light pipes and the first set of symbols are positioned on a first side of the housing; and the second set of light pipes and the second set of symbols are positioned on a second side of the housing.

12 . The aspirating smoke detector device of claim 11 , wherein when the reversible lid is connected to the cover in the second lid orientation:
the first set of light pipes and the first set of symbols are positioned on the second side of the housing; and the second set of light pipes and the second set of symbols are positioned on the first side of the housing.

13 . The aspirating smoke detector device of claim 10 , wherein the second lid orientation is opposite of the first lid orientation.

14 . The aspirating smoke detector device of claim 10 , wherein:
the first pipe configuration and the first symbol configuration are 2×2 array configurations; and the second pipe configuration and the second symbol configuration are 1×1 array configurations.

15 . The aspirating smoke detector device of claim 10 , wherein the second housing includes a printed circuit board (PCB) including a switch such that:
when the cover and the housing are in the first device orientation, the switch is in a first position; and when the cover and the housing are in the second device orientation, the switch is in a second position.

16 . A method of operating an aspirating smoke detector device, comprising:
removing a retaining frame from a cover of the aspirating smoke detector device, wherein the retaining frame is configured to retain a reversible lid to the cover in a first lid orientation and a second lid orientation; removing, from the cover, the reversible lid, wherein the reversible lid includes a translucent portion, a first set of symbols, and a second set of symbols; orienting, when the cover and the housing are to be in a first device orientation, the reversible lid in a first lid orientation such that the first set of symbols are in a first symbol configuration and the second set of symbols are in a second symbol configuration; connecting, in response to the cover and the housing being in the first device orientation:
the reversible lid in the first lid orientation to the cover; and
the retaining frame to the cover;
orienting, when the cover and the housing are to be in a second device orientation, the reversible lid in a second lid orientation such that the first set of symbols are in the first symbol configuration and the second set of symbols are in the second symbol configuration; and connecting, in response to the cover and the housing being in the second device orientation:
the reversible lid in the second lid orientation to the cover; and
the retaining frame to the cover.

17 . The method of claim 16 , wherein the method includes orienting the reversible lid in the first lid orientation such that:
the first set of symbols are positioned on a first side of the cover and located substantially adjacent to light emitted through a first set of light pipes of the aspirating smoke detector device; and the second set of symbols are positioned on a second side of the cover and located substantially adjacent to light emitted through a second set of light pipes of the aspirating smoke detector device.

18 . The method of claim 17 , wherein the method includes orienting the reversible lid in the second lid orientation such that:
