Silent Knight SK-ZONE-6 is a six zone interface module that sends the status of conventional two-wire detector zones to a fire alarm control panel over its signaling line circuit (SLC). It converts a conventional two-wire loop to an SLC loop.
The six inputs share one SLC connection and one external power supply, but each input otherwise works independently. The module supervises both the detector zone and the external power connection, and reports normal, open or alarm conditions. Up to two unused inputs can be disabled.
Features
- Six zone inputs, fully supervised

- Removable plug-in terminal blocks accept 12 to 18 AWG
- Rotary address switches for fast installation
- Two modules fit in the IDP-ACB cabinet
- Mounting hardware included
- Detectors connected must be UL compatible with the module

FAQ
Which panels is the SK-ZONE-6 compatible with?
Silent Knight 6820, 6820EVS, 6808, 6700, 5700, 5808, 5820XL and 5820XL-EVS fire alarm control panels.
Where does it mount?
In the Silent Knight IDP-ACB cabinet, which holds one or two SK-ZONE-6 modules.
Does it need external power?
Yes. The initiating circuits share a common external power supply: 50 mA standby and 70 mA alarm per module.
Which detectors can be connected?
Two-wire detectors that are UL compatible with the SK-ZONE-6; the compatibility list is in installation instruction I56-3441. Each zone uses a 3.9K end-of-line resistor.
