Silent Knight SD505-HEAT Fixed Temperature

The Silent Knight SD505-HEAT Fixed Temperature is a heat detector suit to virtually any commercial setting. The SD505- HEAT is an absolute temperature device. This means that it responds in alarm if the temperature goes above the trip point (programmed at the panel). The SD505-HEAT provides accurate temperature measurement data to the fire alarm control panel. This heat detector is particularly suit to environments where smoke detectors cannot be use because of the presence of steam or cooking fumes, such as in a kitchen.

The Silent Knight SD505-HEAT Fixed Temperature unit is made up of an external mount thermistor with a special design cover that protects the thermistor while allowing maximum airflow. In addition, the thermistor reads the temperature from the air it takes in. It then transmits a signal representing the temperature to the IntelliKnight panel.

If the temperature exceeds the trip point (programmed at the panel), an alarm occurs. Also, the status LED lights continuously during the alarm period. Under normal conditions, the status LED blinks approximately every 15 seconds, indicating that the Head is communicating with the loop.

Some features will be describe below, for example:

• Low profile, 2 inches, including base
• Absolute temperature device
• Uses digital communication protocol
• Simple and reliable addressing
