Compliance

• UL Listed

Key features

• Provides one Form-C relay output switched by SK SLC commands
• Alarm current 0.255 mA max, keeping loop loading minimal
• Operating temperature 32°F to 120°F (0°C to 49°C)
• 10% to 93% non-condensing humidity; weight 6.3 oz (196 g)
• Isolates low-voltage fire alarm output from higher-voltage or non-power-limited loads

The SK-RELAY is an addressable relay module for the Silent Knight SK protocol SLC. It provides a dry-contact Form-C relay output that can switch auxiliary loads — elevator recall circuits, HVAC shutdown, door holders — at addressable points within the 5820XL or 6500 series system (a Honeywell brand). The relay output is electrically isolated from the SLC, protecting panel circuitry from load-side transients.

Verify panel/device family compatibility before ordering.
