Product details
The Silent Knight WSK-RELAY is a SWIFT wireless addressable relay module with one isolated Form C contact. It lets a compatible panel switch a dry contact where running wire would be costly or intrusive, communicating with a gateway over the bi-directional SWIFT mesh.
Typical uses are elevator recall, door holders and fan shutdown. The module is battery powered, and circuit connections to the relay are not supervised by the module.
Key features
- One isolated Form C contact (SPDT)
- Battery powered, two-year minimum life
- 902 to 928 MHz SWIFT mesh radio
- SMB500 box preferred for mounting
Ordering note
This is a module, not a detector base. It is not interchangeable with the wired SK-RELAY or the WSK-MONITOR, which reads contacts only and has a 4-1/2 in. square housing. One WSK-RELAY drives one output device; multiple loads need additional modules.
