Fortress Internal Siren

Linked to the main control panel, this loud (130 dB) siren will instantly sound in case the alarm is triggered by one of the wireless sensors and continue between one and thirty minutes until the system is disarmed. Connected directly into the main system, it does not require a power adapter. Designed to deter intruders and quickly alert of security breaches, the alarm is extremely loud and it can be painful to stand in its proximity for any length of time. Only one Internal Siren can be used with a system.
