SOUND AD­VICE: SIRENS

Home Defender - - Contents - BY HOME DE­FENDER STAFF

Your home alarm is only as good as the at­ten­tion it cre­ates, so add th­ese sirens to your sys­tem now.

Add any of th­ese sirens to your home alarm sys­tem for max­i­mum scare.

Ahome alarm is only as good as the panic (and at­ten­tion) it cre­ates. Be­ing that the siren omits the loud­est and most au­di­ble part of an ac­tual alarm sys­tem, you want to make sure that it’s ex­tremely loud – not just loud enough.

To add to that, most home alarms come with a lack­lus­ter siren typ­i­cally mounted in­doors. For starters, the sirens may ap­pear to be loud when you first hear them, but shut your win­dows and doors and you’ll soon find that it may be hard for even your neigh­bors to hear it.

But re­mem­ber this: While most home alarm sys­tems are pro­grammed to call an emer­gency con­tact, it takes up­wards of 12 to 15 min­utes for the author­i­ties to ar­rive – but it only takes 3 to 5 min­utes for an in­truder to ran­sack your place. So to help de­ter in­trud­ers, our ad­vice is to ei­ther re­place or add a new – and much louder – siren like the ones show­cased here. By adding an ex­ter­nal siren un­der the eaves of your home, you’re not only at­tract­ing the at­ten­tion of your sur­round­ing neigh­bors, but you will lit­er­ally cause most would-be rob­bers to flee. In­stall that same siren of equal or more deci­bels in­doors and it’s sure to cre­ate such an ex­cru­ci­at­ing level of sound that it makes them want to leave im­me­di­ately. Again, the more the mer­rier – and just an­other level of pad­ding in your home-de­fense plan.

With an ar­ray of sirens and horns to choose from, we’ve com­piled just a few of the great op­tions so al­ways be sure to check on the deci­bel each units pro­duces and com­pare it to our DBA chart to get a good idea as to just how loud th­ese lit­tle whin­ers can be.

“... it takes up­wards of 12 to 15 min­utes for author­i­ties to ar­rive — but it only takes 3 to 5 min­utes for an in­truder to ran­sack your place.”

“... an ex­ter­nal siren ... will lit­er­ally cause most would-be rob­bers to flee.”

A home de­fense sys­tem should in­clude an alarm or siren that's loud enough to chase off in­trud­ers.
