The Honeywell evohome Security Internal Battery Operated Siren (SI800MS) is an in house alarm that will alert you to any unusual activity in your house, potentially scaring off any intruders and most importantly, keeping you safe. The system has a long battery life of up to 4 years and it's cream/white colour means it will blend in with the interior decor of your house without being too intrusive. The system has varying user defined sound levels from 95dBA -120dBA meaning it is likely audible whereever you are in the property. Loud sirens are an essential deterrent in any security system and external visual alarms provide a further deterrent.
