Silent Knight WSK-PHOTO-T — SWIFT wireless addressable photoelectric smoke detector with an integral 135°F fixed temperature heat element, supplied in the B501W base.
It sends a digital representation of smoke density across a Class A wireless mesh to a SWIFT gateway, which passes it to the panel, so the panel treats it as a wired addressable detector. Each device has two parents in the mesh, giving a second path if a node stops.
- Photoelectronic sensing chamber plus a 135°F heat detector, address on rotary dials
- Requires a WSK-WGI gateway, one per mesh, up to 49 SWIFT devices
- Four Panasonic CR123A or Duracell DL123A cells, two years minimum life
- 210 µA standby and 5 mA maximum in alarm at 3.3 VDC; radio 902 to 928 MHz
- 32°F to 100°F, air velocity 0 to 4,000 fpm
- 2.4" high, 4.0" diameter in the B501W base, 8.1 oz with batteries
- UL 864 and UL 268; UL S6173 and S6228, FM approved, FCC ID AUBWFSSD
WSK-PHOTO is the same detector without the heat element, rated to 120°F rather than 100°F, so the thermal version has the narrower ambient limit. WSK-HEAT and WSK-HEAT-ROR sense no smoke.
