Silent Knight ISO-6 6-Output Isolator Module

Keep your fire and security networks resilient with the Silent Knight by Honeywell ISO-6 6-Output Isolator Module. Designed for commercial and industrial fire alarm control panel installations, this fault isolator module limits the impact of short circuits by isolating the affected segment so the remainder of the loop continues to function. Featuring six individual, Class B isolator circuits and amber LED indicators on each input, the ISO-6 simplifies troubleshooting and reduces costly downtime. The module operates on standard 32V DC control panel power and uses removable 12–18 AWG plug-in terminal blocks for quick wiring and field servicing. Its automatic open/restore behavior clears faults without technician intervention once a short is removed, helping maintain continuous monitoring and security surveillance coverage. Compatible with Honeywell Farenhyt series panels, the ISO-6 is ideal for fire alarm, security, and integrated monitoring systems that require reliable loop protection. Specify the ISO-6 for new installations or upgrades to improve system uptime—contact your distributor or add it to your next fire alarm design.
