Should the Ph508 power horn have a kind of two tone sound like for example: weee-wooo, weee-wooo or should it stay on continuously like: weeeeeeeeeeeeeeeee
Mine has this wee-woo sound and I'm not sure maybe its defective, or should it be like this? Sounds more like a fire alarm to me than a burglar alarm.
Also, what are the operating temperatures of the ph508 and sh10a?
