this is a special device that's very similar to a fire alarm but this device is also made from the fire alarm company called Wheelock and this is basically a telstro which is a phone flasher that works on a telephone system so anyways I figured I show off two of them and watch the whole video because there's a double trouble at the end of the video by testing two tel strobes at the exact same time on one phone line so anyways guys I hopefully you enjoy the video if you want one of these on eBay or Amazon the model number is PS- 15A
and also if you if you have seizures please don't watch this video and I'm not responsible
so anyways guys hopefully you enjoy this video if you want to see more videos like this please continue supporting the channel. thank you
