Choosing Alarm Sounders
External sounders act as a visible deterrent and provide audible warning outside the property. Internal sirens help alert occupants inside the building and confirm alarm activation in areas where the external sounder may not be easily heard.
Sounder Compatibility
Check whether the sounder is wired or wireless and confirm compatibility with the alarm panel. External sounders may require battery backup, tamper protection and suitable weather resistance.
