Extra Siren Installation Guide
Your Extra Siren is 4 times louder than the alarm built into your Base Station at a whopping 105dB. So it's sure to get the attention of any uninvited guests. It can also play a door chime when Entry Sensors are open, and a countdown when the entry or exit delays are triggered. The Extra Siren is rated for both indoor and outdoor use, so you can install it anywhere within your home such as near the front door or outside, under an eave.
