FCH-T320-R470 Heat detector
General Description
- FCH-T320-R470 thermal differential/thermal maximum detector, conventional technology, with 470 Ohm alarm resistor
- High reliability of detection thanks to evaluation electronics
- Active adjustment of the threshold (drift compensation) if the optical sensor becomes dirty
- Activation of a remote external detector alarm display possible
- Mechanical removal lock (can be activated/deactivated)
- Dust-repellent labyrinth and cap construction
| Operating voltage | 8.5 V DC to 30 V DC |
| Current consumption | < 0.12 mA |
| Alarm output | Increase in current (alarm resistance 820 Ω or 470 Ω) |
| Indicator output | Open collector connects 0 V in the event of an alarm over 3.92 kΩ |
- IP 41
- IP 43 with FAA-420-SEAL or MSC 420
