Hydrogen Leak Detection
For Facility Safety Monitoring

Four Channel Wall Mount Controller
Beacon 410 Model

Note: 4-channel panel described. Also available in 1-, 2-, and
8-channel versions.

The Beacon 410 is a highly configurable, microprocessor-based, flexible and easy to use gas monitor. It simultaneously displays the gas type, readings, and status for 4 channels of gas detection. It can monitor any combination of direct connect sensors (LEL combustibles, Oxygen, Hydrogen Sulfide, Carbon Monoxide, and Carbon Dioxide) as well as any 4-20mA transmitters.

Each channel has 2 fully configurable alarm points with dedicated configurable relays and a built-in silenceable buzzer alarm. There are 5 common relays that can be configured as additional channel relays allowing up to 3 alarm relays per channel.

Outputs include a 4-20mA signal for each channel and a digital (RS425) signal for remote logging of data via a Modbus network. A Min-Max feature retains high & low peak readings for review at any time.

Field calibration is made simple by the easy to use Calibration Mode. An optional high visibility strobe can be mounted on the controller. The unit can be powered from 115/220 VAC, an external 24 VDC source, or a 24 VDC backup battery.

All features and functions of the Beacon 410 are controlled by easy to use menus on the backlit LCD display. The form-C (SPDT) relay contacts are rated at 10A, 250V, reducing or eliminating the need for additional slave relays. All features of the Beacon 410 are built into the unit so you never need to purchase or maintain any “add-on” cards or components.
