L-Series
The System Sensor L-Series collection is PVC’s most popular. It was first released in October 2019. The collection contains 58 devices.
These alarms were tested with moneyLAB’s RSA2000 system and should also be compatible with other systems based on that standard.
IMPORTANT: With Release 25.04, these alarms now use CollectionService. As such, their scripts have been extensively restructured in a way that means that alarms no longer have individual scripts. All alarms are now controlled by the scripts in the “!Scripts_PVC_P03” folder. I recommend you place this folder to ServerScriptService, but because the alarms have no module calls – for which scripts are needed – this is by no means essential.
You should also remove tags from alarms that aren’t part of a system to prevent an issue that, more often than not, prevents alarms that are actually part of a system from working correctly. The “Detagger” script handles this automatically.
