The Apollo 55000-140APO is a Series 65A conventional heat detector fixed to a 135°F alarm threshold, intended for two-wire conventional fire alarm zones. It monitors the surrounding air temperature using a dual-thermistor network that produces a voltage output proportional to temperature, triggering an alarm once the fixed set point is reached.
Key Features
- Fixed-temperature detection set at 135°F, for areas where smoke detection is impractical
- Dual thermistor network for stable, drift-resistant temperature sensing
- Conventional two-wire design for standard fire alarm zone wiring
Technical Specifications
- Detection Method: Fixed temperature, 135°F
- Sensor: Dual thermistor network, voltage output proportional to air temperature
- Series: Apollo Series 65A
