Seco-Larm SH-816S-SQ/B Self-Contained Siren With Strobe Light, 120dB Warble-tone Siren, Audio Input For Broadcasting Messages Or Audio Playback, IP65 Weatherproof, White with Blue Light

Larger than it appears on the pictures and very loud! Gets the job done.

Recently ADT failed us.... An alarm even took place and police were never dispatched. I was then lied to that they were called but because our Alarm Permit was not in force they did not respond... The very next day I received in the mail a renewal for our Alarm Permit! ADT LIED! I have said for years a little over 12 years that we were paying for nothing more than a noise maker.... And now I have one so loud that your ears hurt even at 40 feet! Love it and with the light it's easy to tell which house the noise is coming from. Screw ADT.... Do it your self.

The media could not be loaded. I was looking to replace my old standard siren with one that had a strobe. I am not an alarm expert so I did some research and installed the ENFORCER Self-Contained Siren/Strobe. As you can see it worked very well and the tone siren is really loud. I’ll be purchasing a couple more for my kids homes.

First of all the siren do what the siren should do, which is make it so loud you can’t hear your own ears. The “strobe” is just a blinking LED, and although brighter than most, just is mediocre on the flash. I miss the days of the ol capacitive discharge bulbs.

Very loud , quality built, buying two more
