Intruducing the Qolsys IQ Heat 135 / 200. It offers a selection for the fixed alarm temperature limit of either 135°F or 200°F (57.2°C or 93.3°C). In addition, it has a rate-of-rise feature that activates an alarm if the temperature rises more than 12°F - 15°F (6.7°C - 8.3°C) per minute.

Qolsys is streamlining their products by combining the features of the Qolsys IQ Heat 135, and the Qolsys IQ Heat 200 into a single device. Using an internal jumper, the user can choose a fixed temperature alarm threshold of either 135°F (57.2°C) or 200°F (93.3°C). Based on this jumper setting, a temperature above the selected threshold will cause an alarm.

In addition to the fixed-temperature alarm threshold, the IQ Heat 135 / 200 also has a built-in rate-of-rise detector. If the ambient temperature rises from between 12°F - 15°F (6.7°C - 8.3°C) per minute, an alarm will occur.

Once either alarm threshold has been met, the IQ Heat 135 / 200 will use its transmitter to send an alarm signal to a compatible system. This includes any of the Qolsys IQ Panel 2, IQ Panel 2 Plus, IQ Panel 4, IQ4 Hub, IQ Hub, and IQ4 NS panels with a 319.5 MHz receiver built in. It can likely also be used with Interlogix/GE panels that support this frequency, such as the Simon panels, though we have not tested to confirm this.

The jumper used to set the fixed-temperature threshold has three (3) pins. If the jumper is across the LOW and center pin, the detector is set for 135°F (57.2°C) if the jumper is across the center and HI pin the detector is set for 200°F (93.3°C). If the jumper is removed completely, or lost, then the detector defaults to the high, or 200°F (93.3°C) setting.

The Qolsys IQ Heat 135 / 200 uses a single Panasonic CR123A 3V battery, and the expected battery life is about ten (10) years. Besides how often the detector transmits a signal, the biggest factor in battery life is ambient temperature. When the detector is mounted to the ceiling, the ceiling temperature should never exceed 100°F (37.8°C) under normal conditions. Just know that extreme temperatures, high or low, will likely affect the life expectancy of the battery.

The detector is fully supervised for RF check-in and transmits a signal to the system every 62 - 68 minutes. If the alarm panel doesn't hear from the sensor for a specified period, it will indicate a trouble condition on the zone associated with the IQ Heat. In addition to RF supervision, the detector is also supervised for tamper. If the heat detector is pulled away from the wall or ceiling, it will generate a tamper transmission to the alarm panel.
