GDA-1600

Sixteen Channel Alarm Controller

Product Information

Bacharach’s all new GDA-1600 Controller offers premier performance and functionality in a standalone
controller. From one to sixteen channels, the GDA-1600 is designed to provide operators the most detailed,
real time information about gas concentrations throughout the facility. Information is relayed to the operator
through a large LCD display that shows real time gas concentrations, sensor location, sensor type, as well
as historical data trends. Each channel has three independent, user-programmable alarm threshold values that
allow for flexibility in alarm notification. When alarms do occur, operators are notified via LED alarm indicators
on the front panel, clearly showing which channel is in alarm and the alarm state. Internal relays can also be
utilized to control fans, horns, or beacons when alarm thresholds are exceeded. When responding to alarms,
information is critical. The GDA-1600 provides more details than any other controller on the market today.

Features & Benefits

Accepts up to 16 inputs, outputs and relays
Graphic LCD for real time monitoring and 30-minute/24 hour data trends
Complete calibration functionality for each input channel
Three independent alarm levels per channel
Non-volatile memory retains
