Gas Detection Systems

Two Channel Wall Mount Controller

The Beacon 800
The Beacon 800 is a versatile, low cost fixed system controller
™
for one to eight points of gas detection. It is microprocessor
controlled and is capable of accepting up to 8 separate 4-20 mA
sensor transmitters which can be either 2 or 3 wire. The Beacon
™
800 can be powered by either 24 VDC, or 85-264 VAC. It is
simple to operate and comes complete with a wall mount
installation kit.
The 2 large digital displays have backlighting and easily identify
both the gas type and the gas concentration for all 8 channels
simultaneously. The Beacon 800 is housed in a NEMA 4X rated
™
case for a weather tight seal. This case design complies with lock
out / tag out standards and can be fully secured. An external reset
switch allows alarms to be silenced from outside the controller
housing. The bottom mounted wiring hubs allow for easy wiring.
With 3 amp rated relays, the Beacon 800 can be wired directly
™
to a variety of devices like alarm horns, buzzers, or lights. This
eliminates the need for costly external relays from the controller
to devices. RKI offers the industry’s widest selection of standard
and toxic gas detection sensors, which can be utilized with the
Beacon 800, providing gas monitoring protection for almost
™
any application.
