Abstract

A dangerous condition warning device issues an alarm when a sensed dangerous condition exceeds a predetermined status and has an associated card carrying imprinted protocol and instruction information which is intended to be permanently linked with the device for future reference. The card has first and second generally parallel side edges and a third edge including a tab and is fabricated from a durable and flexible material. A device housing is detachably attachable to a supporting surface for operational mounting. The housing includes a base member having an outside surface including a rear facing portion disposed adjacent the supporting surface when the device is installed for normal operation and a label area in the rear facing portion. The label area includes first and second generally parallel, mutually facing slots suitably spaced apart to retain the card when the first and second side edges of the card are inserted therein. Thus, the card can be permanently stored with the housing by sliding it into the slots before attaching the housing to the supporting surface such that the card can later be accessed by detaching the housing from the supporting surface and withdrawing the card from the slots using the tab.

Claims

1. In a dangerous condition warning device adapted to issue an alarm when a sensed dangerous condition exceeds a predetermined status, which dangerous condition warning device has associated therewith protocol and instruction information which are intended to be permanently linked with said dangerous condition warning device for future reference, means for retaining said protocol and instruction information with said dangerous condition warning device comprising:

A) a card having instruction and protocol information printed thereon, said card having first and second generally parallel side edges; and

B) a housing for said dangerous condition warning device, said housing being detachably attachable to a supporting surface for operational mounting, said housing including;

1) a base member having an outside surface including a rear facing portion disposed adjacent the supporting surface when said dangerous condition warning device is installed for normal operation, said rear facing portion carries an AC plug such that said housing is detachably attachable to said supporting surface by plugging said AC plug into a corresponding socket disposed on said supporting surface; and

2) a label area in said rear facing portion, said label area including first and second generally parallel, mutually facing slots suitably spaced apart to retain said card when said first and second side edges of said card are inserted therein;

whereby, said card can be stored with said housing by sliding it into said slots before attaching said housing to the supporting surface such that said card can later be accessed by detaching said housing from the supporting surface and withdrawing said card from said slots.

2. The dangerous condition warning device of claim 1 in which said card is fabricated from plastic.

3. The dangerous condition warning device of claim 1 in which said card is fabricated from paper coated with plastic.

4. In a dangerous condition warning device adapted to issue an alarm when a sensed dangerous condition exceeds a predetermined status, which dangerous condition warning device has associated therewith protocol and instruction information which are intended to be permanently linked with said dangerous condition warning device for future reference, means for retaining said protocol and instruction information with said dangerous condition warning device comprising:

A) a card having instruction and protocol information printed thereon, said card having first and second generally parallel side edges and a third edge including a tab portion, said card being fabricated from a durable and flexible material; and

B) a housing for said dangerous condition warning device, said housing being detachably attachable to a supporting surface for operational mounting, said housing including;

1) a base member having an outside surface including a rear facing portion disposed adjacent the supporting surface when said dangerous condition warning device is installed for normal operation; and

2) a label area in said rear facing portion, said label area including first and second generally parallel, mutually facing slots suitably spaced apart to retain said card when said first and second side edges of said card are inserted therein;

whereby, said card can be stored with said housing by sliding it into said slots before attaching said housing to the supporting surface such that said card can later be accessed by detaching said housing from the supporting surface and withdrawing said card from said slots using said tab portion.

5. The dangerous condition warning device of claim 4 in which said rear facing portion carries an AC plug such that said housing is detachably attachable to said supporting surface by plugging said AC plug into a corresponding socket disposed on said supporting surface.

6. The dangerous condition warning device of claim 5 in which said card is fabricated from plastic.

7. The dangerous condition warning device of claim 5 in which said card is fabricated from paper coated with plastic.

8. The dangerous condition warning device of claim 4 in which said card is fabricated from plastic.

9. The dangerous condition warning device of claim 4 in which said card is fabricated from paper coated with plastic.
