The roofAlert remote monitoring system is an intrinsically safe automatic roof monitoring installation developed by Holville in conjunction with SCT. The system incorporates a data logging network that automates the collection of roof extensometer readings using the Gen4 Rock-It.
The system is based on a single pair cable that daisy chains the instruments along an excavation and relays each individual Tell Tale reading to the surface via a control box. An interface on the surface then allows for routine monitoring and Tell Tale database maintenance.
The instrument still maintains a visual read out that can be monitored manually, as it is currently used. The addition of Holville’s roofAlert module (rAMs) then allows the Tell Tale to be connected to the system and monitored remotely
