The ADT indoor siren is a wireless sounder that adds a loud alarm inside the house and is enrolled with the control panel so that it sounds when the system alarms. Placement and enrolment both matter. For placement, put the siren where it can be heard through the house, usually on a hallway or landing wall near the bedrooms and away from the panel's own sounder, which has a shorter range, and keep it out of a cupboard or behind furniture, which muffles it.
The checks in more detail
It needs power: some indoor sirens run on batteries and others plug into a wall outlet with a backup battery, so check which model you have in the manual. Fit the batteries or connect the power and keep the siren within a few meters of the panel for enrolment, since the enrolment signal is short range. To enrol it, put the panel in device or sensor programming, usually protected by the installer or master code,
and trigger the siren's enrolment, by closing the case or pressing its learn button, as the manual explains, so that it sends its signal. The panel beeps or shows the new device, and you give it a name and set how it behaves, for example sounding on burglary and fire alarms. SafeWise's guide notes that the sequence differs between panel models, so identify yours first. After enrolling, test it in the panel's test mode, with the monitoring company told, and listen from the farthest bedroom with the door shut.
If the siren does not sound, check the batteries or power, the enrolment and the panel's output settings. A siren that chirps on its own is signalling a low battery or a tamper, so check both. Test the siren monthly with the system test, and replace batteries once a year. Warn the household before a test, since the sound is loud enough to be painful close up, and keep pets and children clear.
