Abstract (en)
A fire alarm testing device including an electrical-switch assembly, and internal circuitry. The electrical-switch assembly includes a face-plate with the face-plate including two screw-holes, a control knob, two voltage/resistor measuring points, a plurality of electrical contacts, and two mounting screws. The internal circuitry is mechanically and electrically coupleable to the face-plate, and electrically communicable with a fire alarm system. The control knob also includes four rotatable positions including normal, open, ground, and short such that the fire alarm system is testable by rotating the knob. The electrical-switch assembly is rated for 0-40 volts direct current and is rated up to 350 milliamps and is rated up to 3.5 continuous current-amps. Preferably, electrical-switch assembly is water resistant sealed from dust and debris. Protective caps or plugs are installed where required to prevent foreign objects into the device.
