IQ QS5519-840 Wireless 319.5MHz Heat Detector

The IQ Heat 135/200 wireless heat detector uses electronic processing to detect heat conditions plus a wireless transmitter (319.5 MHz) in one unit. The micro-processor trips the transmitter when the temperature at the detector location reaches a fixed temperature of 135°F (57°C) or 200°F (93°C), depending on selection, or senses a rate of rise at 12°F to 15ºF (6.7 to 8.3ºC) per minute.
