VEHICLE EXHAUST GAS DETECTOR

GENERAL DESCRIPTION:

The GVU-1 ventilation control monitor combines toxic gas sensing and time-based fan control modes in an all solid-

state, low maintenance, cost effective product.

The GVU-1 controller consists of the power supplies, solid state clocks, time delays, and output relays. It can con-

tinuously monitor one of the following Toxalert sensors: GVU-CO carbon monox-

ide sensor, GVU-CO

carbon dioxide sensor, GVU-NO

nitrogen dioxide sensor or

GVU-VOC diesel smoke/air quality sensor. See last page for ordering informa-

tion. (Please refer to applicable sensor data sheets).

TIME CONTROL:

The systems hourly timeclock outputs to the fan-on relay once per hour causing it

to energize. The on time of the fan-on relay is user adjustable, in one minute

increments from 1 to 8 minutes. The hourly timeclock operates in this manner

irrespective of sensor reading, and may be disabled, if desired. To disable the

hourly clock operation, place switch S3 to RST (RESET) position.

VENTILATION CONTROL:

Should a high toxic concentration occur (above user adjustable alarm level), a 30

second delay timer will start. Should the concentration persist through the delay

period, the “alarm” clock is activated. The “on” time of this clock is user adjust-

able in discrete settings from 1 to 8 minutes and its setting is independent of the

hourly clock setting. Upon activation of the “alarm” clock, the “fan-on” relay

energizes and remains energized until the “alarm clock” times out. Should the

concentration still be above the alarm level, the “fan-on” relay shall remain ON

and the alarm relay shall energize. This condition is maintained until the concen-

tration drops.

In the event of a power failure, the control unit sets itself to an alarm condition

upon power restoration. Thus, fan activation is assured, clearing out any accumu-

lated toxic gases.
