How to troubleshoot a siren that doesn't sound on a Honeywell OMNI 624?

If the siren/speaker on your Honeywell Security System isn't producing sound, the siren/speaker itself might be faulty. To check, connect 12VDC directly to the siren/speaker; if no sound is produced, replace it. Another potential cause is faulty wiring; inspect the wiring for open or short circuits and replace if necessary. Finally, the panel/bell output may be faulty. Check terminals 3 (+) & 4 (-) for 12VDC when the panel is in alarm (if programmed for bell output); if no voltage is measured, replace the panel.
