Silent Knight WSK-RELAY — SWIFT wireless addressable relay module with one isolated Form C contact.
The module lets a compatible panel switch a dry contact where running wire is costly or intrusive, communicating over the bi-directional SWIFT mesh to a gateway. Typical uses are elevator recall, door holders and fan shutdown. It is battery powered, not mains powered, and circuit connections to the relay are not supervised by the module.
- Contact: one isolated Form C set operating as an SPDT switch
- Ratings include 3 A at 30 VDC resistive non-coded and 2 A at 25 VAC
- Power: four CR123A lithium cells, two year minimum life
- Radio: 902 to 928 MHz, 17 dBm maximum transmit power
- Size: 4-1/4 in. H × 4-1/4 in. W × 1-1/2 in. D
- Mesh: one WSK-WGI gateway per mesh, up to 49 SWIFT devices
- SMB500 box is the preferred mounting
This is a module, not a detector base. Do not substitute the wired SK-RELAY, nor the WSK-MONITOR, whose housing is 4-1/2 in. square and which only reads contacts. One WSK-RELAY drives one output device; two in parallel are needed for multiple loads.
