With this indoor siren from Heiman no burglar is safe anymore. Due to the fixed power supply, the siren is always supplied with power. This is handy for a product that you want to use in a Z-wave alarm system.
The product has a beautiful design, a built-in backup battery for up to 1 hour and a noise level of up to 95dB. Taking the siren out of the socket during the first hour after it goes off is therefore totally useless.
In addition to this siren, the Heiman brand also has many other beautiful products available with a good price-quality ratio. Click here to go to the manufacturers page
