MSA Brand gas monitor Model Z-Gard COmbo

The MSA Z-Gard COmbo Gas Monitor features an integrated carbon monoxide sensor,

and is ideal for use in small garage monitoring and ventilation control applications.

Generally wall-mounted in the area where the target gas is to be measured, the Z-Gard COmbo Gas Monitor can also act as a controller,

managing up to seven additional remote Z-Gard Gas Sensors via RS-485 serial data bus connections.

Integrated carbon monoxide sensor.

۱۰۰ and 200 ppm full scale ranges available.

Local audible/visual alarm status indication.

Relay contact outputs interface with air handling equipment to control the vehicle exhaust emissions or general air quality inside buildings.

Two levels of alarm, plus fault relays are field programmable.

The alarm relay can be made to latch in the activated position even after the alarm has been cleared.

Pushbutton to silence an audible alarm or reset the latching alarm relays.

Sensor status feature provides an indication if either the integral sensor or any other remote sensor fails to communicate properly.

Additional Z-Gard remote gas sensors may be connected to the monitor’s RS-485 network port. CO, NO2, LEL Combustible

۴-۲۰ mA output representing the highest reading generated from the remote sensors and onboard sensor.

Units available with LED readouts and status LEDs or status LEDs only

۴-۲۰ mA analog output can be integrated with PLC, DCS or building automation systems.
