The RKI Beacon 110 is a low cost fixed system controller for one point of gas detection. It is microprocessor controlled, versatile and simple to install and operate. It accepts RKI sensors directly for LEL combustibles, oxygen, hydrogen sulphide or carbon monoxide, and can also accept any 4-20 mA transmitter (2 or 3 wire, 24 VDC). Sensors can be mounted directly on the Beacon 110 housing or wired remotely from the controller.
The 10 A rated relays are strong enough to power external alarms and horns directly. The backlit digital display shows the gas type and concentration together. The controller is housed in a NEMA 4X rated case for a weather tight seal; the case complies with lock out / tag out standards and can be fully secured. An external reset switch silences the alarm from outside the housing, and the Beacon 110 ships with a wall mounting kit.
RKI offers a wide selection of standard and toxic gas sensors that can be used with the Beacon 110, covering almost any application. A partial list of detectable gases:
