RKI Instruments Beacon® 200 two-channel wall-mount controller (115–220 VAC, no sensor): a powerful, low-cost, microprocessor-controlled fixed system controller for two points of gas detection.
Key benefits
- Simultaneous readout on 2 channels with backlit display of gas type and concentration
- Two alarm levels per channel; discrete and common relays rated 10 A to drive most external alarms and horns
- Connects directly to RKI LEL, oxygen, H2S or CO sensors, or any 4-20 mA transmitter (2 or 3 wire, 24 VDC)
- Sensors mount at the housing or wire remotely
- 4-20 mA outputs
- NEMA 4X housing for corrosion resistance and weather-tight seal; complies with lock-out/tag-out standards
- External reset switch silences alarm from outside the housing
- Wall mounting kit included
- Made in the USA
