To change the relay level, navigate to
Settings > Relay Settings > Relay #
. Then scroll to the
bottom and tap on “Relay Level”. Follow the instructions on screen to determine the correct
setting.
Connecting the External Alarm
This control panel comes standard with an internally mounted alarm. If the target gas
concentration exceeds the zone alarm setpoint and remains there for the duration of the on-
delay, this alarm will sound. Any relay contacts can be used to connect an external alarm. To
synchronize the internal control panel alarm with external alarms, make sure the setpoints and
delay times are the same in both the
Zone Settings
and
Relay Settings
screens.
Figures 1 and 2 on page 20 show typical alarm wiring.
Connecting the Voltage or Current Proportional Output
The GDCP-Touch and GDCP-ExpansionPack include circuits that provide either a current loop
or voltage proportional output. Each output produces a linear response over the full scale
range of the average of all connected sensors in a zone. Every zone configured on the control
panel can accommodate one of these outputs. A detailed description of these outputs can be
found starting on page 39.
Applying Power For the First Time
Once all the wiring connections are complete, the system is ready for power to be applied. The
first 2.5 minutes after the power is turned on serves as a warm-up period. During this time, the
control panel will display “--” in place of gas concentration values on the
Zone
Screen
and
Relay
Screen
. All Level 1 relays will also be active. Once the warm-up has finished, the gas
concentration values will appear. In most cases, the gas concentration will be “0” or “0.0”.
However, if the target gas is present in the monitored area, the display will indicate the actual
concentration. All menus and features of the control panel are accessible without waiting for
the warm-up timer to expire.
