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.
