A fault tolerant system may be used in lieu of complete duplication of the system if every component in the fault tolerant system, including the software and power supply, is duplicated.All OnGuard system solutions that are to be UL1076 compliant systems must also meet the requirements specified in Section 25A of the UL1076 (Proprietary Burglar Alarm Units and Systems Standard for Safety). This requirement outlines the need for host monitoring redundancy. Host monitoring redundancy can be accomplished in many ways, but the standard is clear as to receiving equipment methods, recovery time, surge suppression and system configurations. Contact Lenel if configuration assistance is required.All inputs must be supervised for UL1076 installations.
