Intelligent Addressable Fixed Temperature Heat Detector KI-HFD

Intelligent Addressable Fixed Temperature Heat Detector KI-HFD

Manufacture: kidde

Product code: KI-HFD

KI-HFD Fixed Temperature Heat Detector ⭐✅ provides a 135
°F (57
°C) fxed-temperature heat sensor for the detection of heat due to fre. The heat sensor monitors the temperature of the air and determines whether an alarm should be initiated.

Product information

The KI-HFD is an intelligent fixed-temperature heat detector that contains a fixed-temperature heat sensor rated at 135 °F (57.2 °C). It does not have a rate-of-rise function. The heat sensor monitors the temperature of the air in its surroundings and the detector analyzes the data to determine when the air temperature near the detector exceeds the device’s alarm point.

Application

The KI-HFD combination fixed temperature/rate-of-rise heat detector provides a 15 °F (9 °C) per minute rate-of-rise heat sensor for the detection of fast-developing fires, as well as a 135°F (57°C) fixed temperature sensor for slow building-fires. The KI-HFD fixed temperature detector provides a 135°F (57°C) fixed temperature sensor for slow building-fires.

Isolator Detector Base, KI-IB, KI-IB4

This base includes a built-in line fault isolator for use on Class A circuits. A detector must be installed for it to operate. The isolator base does not support the GSA-LED Remote LED.

The isolator operates as follows:

- a short on the line causes all isolators to open within 23 msec

- at 10 msec intervals, beginning on one side of the class A circuit nearest the loop controller, the isolators close to provide the next isolator down the line with power

- when the isolator next to the short closes, it reopens within 10 msec.

The process repeats beginning on the other side of the loop controller.

Relay Detector Base, KI-RB, KI-RB4

This base includes a relay. Normally Open or Normally Closed operation is selected during installation. The dry contact is rated for 1 amp (pilot duty) @ 30 Vdc. The relay’s position is supervised to avoid accidentally jarring it out of position. The KI-RB can be operated as a control relay if programmed to do so at the control panel. The relay base does not support the GSA-LED Remote LED.
