Hazardous detection call point stations

1. A hazardous detection call point station, comprising:

a common rear housing;

a front housing, wherein the common rear housing and the front housing are configured to be coupled to form a housing defining an interior; and

an actuator cylinder positioned at least partially within the interior;

wherein, upon breaking a glass front or depressing a button of the station, the actuator cylinder is biased to rotate to complete a circuit and thereby send an alarm notification to a main panel at a remote location; and

wherein the actuator cylinder is common to both the glass front and button of the station.

2. The hazardous detection call point station of claim 1 , further comprising at least one first spring to force the glass front against the actuator cylinder to rotationally hold the actuator cylinder in a normal position.

3. The hazardous detection call point station of claim 2 , further comprising at least one second spring positioned to rotate the actuator cylinder to an alarm position upon breaking of the glass front.

4. The hazardous detection call point station of claim 1 , further comprising a stem member positioned with a front portion adjacent to the button and a rear portion contacting the actuator cylinder to rotationally hold the actuator cylinder in a normal position.

5. The hazardous detection call point station of claim 4 , wherein the rear portion of the stem member defines a groove so that, as the button is pressed, the stem member is moved until the groove allows the actuator cylinder to rotate to an alarm position.

6. The hazardous detection call point station of claim 5 , further comprising at least one spring to rotate the actuator cylinder from the normal position to the alarm position.

7. The hazardous detection call point station of claim 1 , further comprising a key to allow the station to be reset from the alarm position to the normal position.

8. The hazardous detection call point station of claim 1 , wherein the rear housing defines a space in which circuitry is positioned, and wherein the rear housing defines one or more opening through which wires are run.

9. The hazardous detection call point station of claim 1 , further comprising a multi-color sequencing light to indicate a status of the call point station.

10. The hazardous detection call point station of claim 1 , further comprising one or more resistors or diodes electrically potted within a snap-in module.

11. The hazardous detection call point station of claim 1 , further comprising a removable faceplate for covering the front housing, the faceplate being colored.

12. The hazardous detection call point station of claim 1 , further comprising a movable rail upon which a switch is positioned, the rail being movable relative to the actuator cylinder.

13. A hazardous detection call point station, comprising:

a common rear housing;

a front housing, wherein the common rear housing and the front housing are configured to be coupled to form a housing defining an interior; and

an actuator cylinder positioned at least partially within the interior;

wherein, upon breaking a glass front, the actuator cylinder is biased to rotate to send an alarm notification.

14. The hazardous detection call point station of claim 13 , further comprising at least one first spring to force the glass front against the actuator cylinder to rotationally hold the actuator cylinder in a normal position.

15. A hazardous detection call point station, comprising:

a common rear housing;

a front housing, wherein the common rear housing and the front housing are configured to be coupled to form a housing defining an interior;

an actuator cylinder positioned at least partially within the interior;

a button accessible from the front housing; and

a stem member positioned with a front portion adjacent to the button and a rear portion contacting the actuator cylinder to rotationally hold the actuator cylinder in a normal position;

wherein, upon depressing the button of the station, the actuator cylinder is biased to rotate to complete a circuit and thereby send an alarm notification to a main panel at a remote location.

16. The hazardous detection call point station of claim 15 , wherein the rear portion of the stem member defines a groove so that, as the button is pressed, the stem member is moved until the groove allows the actuator cylinder to rotate to an alarm position.

17. The hazardous detection call point station of claim 16 , further comprising at least one spring to rotate the actuator cylinder from the normal position to the alarm position.

18. The hazardous detection call point station of claim 15 , further comprising a key to allow the station to be reset from the alarm position to the normal position.
