Wireless alarm siren with flash

Wireless alarm siren with flash.

An outdoor siren with flashing lights significantly increases the security of your alarm system. If the alarm is triggered, the outdoor siren emits a loud 104 dB sound and flashes.
This will stress a burglar and make a break-in troublesome. The siren is mounted outdoors for optimal effect, because it draws extra attention from neighbors and passers-by.
At least one outdoor siren with flashing lights also lets you deactivate the control panel's built-in siren and keep the panel away, for example in a cabinet, so that a burglar cannot find it. You can set the outdoor flashing siren to confirm with short beeps and flashes when the alarm is armed or disarmed.
Tamper protection.
The outdoor flashing siren is protected against tampering.
This means that if someone tries to open or remove the siren, the internal anti-tamper spring is activated and the alarm is triggered.
