  • Patent number: 6674032
    Abstract: A manual call point having a housing base (1), a cover and an alarm insert with a fragile panel (4), a printed-circuit board (3), a switching element (6) and an actuating mechanism. The actuating mechanism for the switching element (6) is formed by a pivoting lever (7) resting on a lateral edge of the panel (4), the pivoting lever (7) pressing on the switching element (6) in the normal state of the manual call point and holding the switching element (6) in a closed position. When the panel (4) is smashed the pivoting lever (7) pivots, so the switching element (6) is opened. The switching element (6) is arranged on the printed-circuit board (3) and comprises a flexible end switch. The manual call point also contains a device for triggering a test alarm comprising a switching lever (9) to displace the panel (4) until the pivoting lever (7) is released and comprises a member (10) to actuate the switching lever (9).

  • Patent number: 6097279
    Abstract: An improved retractable tamper resistant annunciator that can be mounted flush in a supporting structure is described. The annunciator mechanism includes a housing that has an actuatable cover. Signaling devices are enclosed within the housing, and can be selectively actuated when the cover is opened. A mechanism to open and close the cover to expose the signaling devices or to cover the signaling devices include a reversible motor structure. Alternative mechanisms to open and close the cover include biasing structures to move the cover in a first direction and an electrical device to move the cover in a second direction.

  • Patent number: 5831543
    Abstract: A frame for supporting a sheet of glass over a fire alarm signal switch mounted on a wall. The frame is of the type which holds the glass over the switch so that the alarm signal can only be operated by breaking the glass. The frame has a cover member with an open bottom so that when the glass is broken to operate the alarm the resulting shards of glass fall through the open bottom of the cover member so that they do not injure the operator.

  • Patent number: 4857679
    Abstract: An alarm switch has a box for mounting on a supporting surface, a front plate movably mounted in the box, a frangible element having a plurality of frangible areas spaced in succession thereon and each of which can be broken off the frangible elements, a stop element on either the box or the front plate, and the frangible element being on the remaining one of the box and the front plate, the stop element and the frangible element being positioned for, when the front plate is moved from a normal position relative to the box, the stop element and one of the frangible areas are engaged for causing the frangible area to be broken off the frangible element, and the frangible element and the stop element being shiftable relative to each other for, after one frangible area has been broken off, bringing the stop element and the next frangible area in succession into position for being engaged with each other when the front plate is moved again, and a switch unit operatively connected to the front plate for being oper

  • Patent number: 4616316
    Abstract: A medication compliance monitoring system consisting of a blister pack having an array of plastic blisters defining compartments for medication, with a frangible non-conductive backing sheet having conductive traces behind the compartments which are respectively ruptured when the medication doses are removed. The blister pack is detachably connected to an electronic memory circuit via a multi-terminal male connector tab on the backing sheet, wired to the conductive traces, and a corresponding female connector with terminals wired to the electronic memory circuit. The electronic memory circuit addresses each individual trace periodically at a constant time interval over a predetermined extended period of time to determine if it is intact. The electronic memory circuit detects the ruptures and stores the time data thereof over said extended period of time.

  • Patent number: 4280120
    Abstract: This disclosure relates to an apparatus for fire alarm signaling which is economical and versatile and which makes use of the properties and characteristics of the material of which it is made. All components of the assembly snap together. An auxiliary cover as well as the main cover may be used. A lower break-rod is mounted on the base and cammed aside as the main cover is closed and then the break-rod returned to a position to be broken in response to opening the main cover, an upper break-rod may be associated with the auxiliary cover. Up to three switches may be provided and each has a latched position. A simple tool is used to release the switch latch. The latch comprises an integral part of the base and/or switch stems. During assembly selected elements may be selectively oriented to make any switch have either normally-open or normally-closed contacts. The catch between the main cover and base permits easy actuation and yet inhibits false actuation in response to a blow. No internal wiring is required.

  • Patent number: 4162485
    Abstract: A multi-zone fire protection system in which each protected zone is provided with a detector for producing an alarm signal in response to the presence of combustion products, a source of fire extinguishing agent, and a pull box station manually operable to induce discharge of the extinguishing agent into the protected zone. Each pull station possesses a signal lamp that can be energized to signal an abnormal condition to personnel present in the area. A signal lamp in a given zone is energized via a central control panel in response to an alarm signal from a detector associated with that zone, thereby clearly indicating to personnel at hand the specific zone in which a fire has been detected.
