Gas Alarm
The Series GA-170 Gas Alarm system provides a reliable
and simple solution for gas detection applications. The
GA-170 Gas Alarm incorporates a simple modular design
that can integrate a variety of gas sensor types with up to
four sensors per alarm module. The digital alarm module
is controlled through a user-friendly interface consisting
of push-buttons and a two line, sixteen character, alphanumeric, backlit LCD Display. The digital alarm module is
housed in a NEMA-4X enclosure, and includes visual and
audible alarms. The electrochemical gas sensor(s) can be
located up to 1000 feet (300 m) away from the alarm module. The alarm module includes common contact relays
and adjustable alarm contact relays for each sensor. All
sensor contact relays are user adjustable and High Alarms
can be set as latching or non-latching and failsafe or nonfailsafe. Battery Back-Up is available as an option.
Configuration
Sensor configuration mode is entered using a password and then adjusted using push buttons. Latching and
Failsafe alarm options are also password adjustable.
Operation
Simple menu driven, push-button controlled programming is
performed on the alarm module. Alarm outputs are provided
to activate external devices. A front panel push button function
is used to acknowledge/deactivate latching alarms. A contact
input is provided for remote acknowledge of latching alarms.
Front Panel display and LED’s provide continuous and clear
operation status.
Maintenance
Gas sensors can be replaced and/or recalibrated through the
push-button menu. Sensor types can be easily changed.
Calibration
Contact Hydro Instruments for calibration gas and sensor
testing devices.
