cGas Detector for Indoor Public Spaces - Installation Manual
Rev. A | 2020.11
7 BASIC SYSTEM OPERATION
The cGas Detector continuously monitors target gas concentrations on one or
two confi gured channels. It must be connected to a controller, control panel or
BAS / BMS / DDC system; the cGas Detector is not a standalone gas detection
system.
FOR THE FULL SYSTEM OPERATION INSTRUCTIONS, INCLUDING
CALIBRATION AND SENSOR REPLACEMENT,
REFER TO THE OPERATION
MANUAL
.
7.1 Power Up and Warm-up Process From Factory
Upon application of power to a cGas Detector received from the factory, the
LCD display will turn on and rotate through several info screens that differ
depending on the confi guration of the transmitter (number of channels used,
type of communication, etc.). The warm-up period takes between 2 and 5
minutes depending on the gas sensor type.
NOTE:
The cGas Detector will be visible on the controller / BAS / DDC system
during the warm-up countdown but a correct reading will not show up until the
unit has fi nished the warm-up period and the sensor(s) has stabilized.
All alarms will be disabled during the system warm-up period. After the
warm-up period, the system may exhibit gas alarm condition(s) if one or
both of the sensors has not completely stabilized during the warm up period.
This is normal and the length of time the gas alarms exist is dependent upon
the length of time since the unit was last powered up, and the state of the
environment it is installed in.
