MT4
The Wheelock MT4 collection is PVC’s most recent, having first been released on 24 April 2024. The collection contains 5 devices. If you want to be more technical, it contains 7, as one device combines three models.
These alarms were tested with moneyLAB’s RSA2000 system and should also be compatible with other systems based on that standard.
IMPORTANT: With Release 25.08, 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_P11” 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.
