For applications where multiple safety mats are needed, a zone monitor can be used. It acts as a control box, while eliminating the need for a junction box for multiple safety mat installations. Additionally, it has a diagnostic feature to determine which mat or mats have been tripped. The zone monitor is available in two models: one which monitors 1-4 safety mats, and another which monitors 1-8 safety mats.
If the diagnostics of an entire perimeter safeguarding system including safety mats and perimeter/point-of-operation light curtains, safety interlocked barriers, and interlocked cables are required, a latch-out/reset zone-control unit may be required.
