Abstract:
1. A mechanical sensor coupled to a pneumatic actuator in a fire suppression system having a latching solenoid coupled to a primary vessel and at least one slave vessel, with the pneumatic actuator including a nose piece, the pneumatic actuator coupled to a control unit and to a pressure valve on a slave vessel, the sensor comprising: a disk configured for reciprocal, axial movement within a first portion of a first bore defined in the nose piece; an electrical switch disposed in a second bore defined in the nose piece, the electrical switch coupled to the control unit; and a switch push pin disposed in a portion of the second bore, with the switch push pin in physical contact at one end with the electrical switch, and with a second end extending into the first bore, wherein when the pressure valve is coupled to the pneumatic actuator, the pressure valve contacts the disk and moves the disk back against the switch push pin to change the status of the electrical switch to indicate that the pressure valve is properly coupled to the pneumatic actuator and slave vessel.
