Silent Knight WSK-PHOTO-T-WHITE SWIFT Wireless Photoelectric Smoke Detector with 135F Thermal

The Silent Knight WSK-PHOTO-T is a SWIFT wireless addressable photoelectric smoke detector that also contains a 135°F fixed temperature heat element, and it comes in the B501W base. JEM Systems Canada supplies it with shipping across Canada.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.
