Silent Knight WSK-HEAT — SWIFT intelligent wireless fixed-temperature heat detector, 135°F, with its B501W base and batteries.
A SWIFT detector is not standalone. It joins a Class A wireless mesh in which every device holds two parents, so traffic still reaches the panel if one node drops, and the mesh hops frequencies against interference. The mesh terminates at a WSK-WGI gateway, which sits on the panel SLC.
- Fixed-temperature set point 135°F (57°C); open-area protection at 50 ft spacing under UL 521
- Requires a WSK-WGI gateway; one per mesh, supporting up to 49 SWIFT detectors or modules
- Radio 902–928 MHz; addressable code wheels and two panel-controlled LEDs
- Four Panasonic CR123A or Duracell DL123A batteries, included; 2 year battery life
- 2.4" high, 4.0" diameter in its B501W base; 8.1 oz with batteries
- UL 864 and UL 268; panels 6700, 6808, 6820 and 6820EVS
Order the right element. WSK-HEAT-ROR is the rate-of-rise model (15°F per minute) and WSK-PHOTO-T the photo/thermal combination; all three share one datasheet and this base, so only the model number separates them on a shelf.
