I have a system of smoke detectors throughout my house - one detector per room. They seem to be all sync'd with one another. Every 45 seconds to 2 minutes, the detector downstairs will beep one time. I reset them once (or thought I did anyway) but it still beeps. Why is this?
Passive devices: 1) Fuse 2) Circuit breaker 3) Wire Insulation such as XLP, plastic, etc. 4) Lightning Arrester 5) Porcelain (insulators, bushings) 6) Rubber Gloves 7) Rubber Overshoes 8) Rubber Selves 9) Fiberglass bucket liners for bucket trucks 10) Wire grounds making up ground grids or mats 11) Fence placed around a substation 12) Wood poles 13) Air Break Switch Active Devices: 1) Oil Circuit reclosing switch 2) Vacuum Circuit switch 3) Thyristors of all kinds 4) Solid state relays 5) RCD 6) Arcing Fault circuit breaker Hope this helps, Newton1Law
if you're looking for eye protection, you MUST find goggles that are SHATTERPROOF ordinary sun glasses or thick lenses wont work because they can shatter. [bb + glasses shrapnel blindness] you're better off going to sports authority or spend more than 10$ for a face mask that will protect your eyes and face. or you can get a paintball helm. personally i use a face mask
