Fortress Internal Siren Description
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.

Order was placed, thought it would ship within a few days, took into the next week to ship. Reached out to them to find out when it was going to ship, was advised it would ship after it was finished being programmed. Item did ship eventually, and then it arrived and was missing one of the extra key fobs we had paid for, so now I am back to reaching out to customer service and waiting for the rest of the order to be fulfilled.

Does this siren use a standard 3.5 mm plug? I ask because I would like to use a standard 3.5 mm male to female extension cable.


Hello Ray, Yes, this white plug in siren uses a standard 3.5mm plug. Thanks, Jessica Customer Service Manager


With the WiFi TSS and this internal siren, how does one turn off the arm/disarm chirp (which is far too loud)


Hi, Christian, To turn this feature off, go into the main panel and into Sensors. From there, go to Remote, and select the zones in which your key fobs are (probably the first few). In each zone, turn "sound" off (achieved by selecting the zone, then scrolling down into "sound"). Turning off "panel sound" in the bottom of each zone will disable the siren chirp when you use the main panel to arm or disarm, while turning off "sound" will disable it when you use the key fobs. This can be found on page 24 of the manual as well, in case you ever need it again! Let me know if I can answer any other questions! Regards, Amanda, Fortress Security Store


can I make the cable of the siren longer by cutting it and adding more cable? thanks


Hello Alejandro, You can extend the siren by attaching speaker wire to the siren wire. However, note that cutting the wire will void the warranty if the siren is damaged. Thanks, Jessica
