So what is a CAT 3 system? Safety systems that do not naturally fail safe (Normally Open or NO) need to check that they are working correctly before they are relied upon by the gate system. A CAT 2 system will check that everything is working correctly before the gate system operates and is considered to be an extremely effective compliant system. CAT 3 systems constantly check the equipment is working before the gates start to move and while they are moving. CAT 3 is often preferred over CAT 2 systems, however we have been advised that both CAT 2 and CAT 3 systems are seen as being equally compliant. As are some naturally safe systems the use a NC circuit.
