Jablotron has a complete range of sirens, both indoor and outdoor, as well as wireless and wired. Jablotron's siren series is suitable for most scenarios, but external sirens can actually be attached as many as needed. All sirens meet the requirements of Insurance and Pensions for insurance-approved alarm equipment. This means that, among other things, there is a backup battery and sabotage monitoring in all sirens. The sirens can also be used as an acoustic indication, for example beeping when the back door is opened or movement around the house.
Note that fire detectors (both wireless and wired) can act as sirens in the event of both fire and burglary.
