RKI Air Alert Transmitter (H2S) w/AC, 3-color LEDs & buzzer

$2,830.38

Ships in 6 - 8 weeks

Description

The RKI Air Alert Stand-Alone H2S Transmitter is a wall-mount hydrogen sulfide gas detector powered by AC (115–240 VAC) with 4-20 mA analog and RS-485 Modbus outputs. Magnetic switches allow non-intrusive calibration and full system diagnostics while the unit remains in service.

Compatible with AirLink 7010, AirLink 7032, Beacon 110, Beacon 410, or Beacon 800 controllers.

Applications: Petrochemical plants, Refineries, Water & wastewater treatment plants, Pulp & paper mills, Manufacturing facilities, Chemical plants

Key Features:

  • Electrochemical sensing technology
  • 115–240 VAC power with power cord & cable grip
  • 3-color LED alarms with audible buzzer
  • Operating temperature: -40°C to +70°C
  • 3 push-button interface with non-intrusive magnetic switches
  • Graphical LCD with LED backlight
  • Outputs: 4-20 mA (3-wire) analog and RS-485 Modbus
  • Not equipped with onboard relays
  • 1-year warranty

Frequently Asked Questions

What is the RKI Air Alert Transmitter used for?

The RKI Air Alert is a wall-mount, stand-alone hydrogen sulfide (H2S) transmitter designed for continuous fixed-point gas detection in industrial facilities. It provides real-time visual and audible alarms and can relay 4-20 mA or RS-485 Modbus signals to plant control systems or RKI Beacon controllers.

What H2S concentration ranges are available?

The Air Alert is available in six standard ranges: 0–10 ppm, 0–25 ppm, 0–50 ppm, 0–100 ppm, 0–500 ppm, and 0–2000 ppm. Select the range that matches your specific process or regulatory monitoring requirement.

What output signals does the Air Alert support?

The unit provides a 4-20 mA (3-wire) analog output and RS-485 Modbus digital output, making it compatible with most plant DCS, PLC, and building management systems, as well as RKI Beacon series controllers.

What OSHA standard applies to H2S detection in workplaces?

Under 29 CFR 1910.1000, OSHA sets the permissible exposure limit (PEL) for hydrogen sulfide at 20 ppm as a ceiling value (50 ppm peak for 10 minutes if no other exposure). Fixed detection systems like the Air Alert support compliance monitoring — consult your industrial hygienist for your specific alarm set-point strategy.

How does calibration work on the Air Alert?

The Air Alert uses three magnetic non-intrusive switches (ADD, MENU, SUB) that allow technicians to perform field calibration and full diagnostics without opening the enclosure — important in classified hazardous areas. PK Safety offers in-house RKI calibration and service; call 800.829.9580 to schedule.

Which RKI system controllers is the Air Alert compatible with?

The Air Alert Transmitter is compatible with the RKI AirLink 7010, AirLink 7032, Beacon 110, Beacon 410, and Beacon 800 multi-channel controllers.
