LPT-M - Operation Manual
6.3 Power Up and Warm-up
The current gas level reading can be monitored at any time during normal operation using the
display. The display will be backlit when the menu is in active use.
Upon application of power, the device will enter the warm-up period and display a countdown of
the time remaining before it is done warming up.
NOTE:
The LPT-M will be visible on the 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.
After the warm up period (3 minutes), the device may exhibit gas alarm conditions if the sensor has
not completely stabilized during the warm up period. This is normal and the length of time the gas
alarm exists is dependent upon the length of time since the unit was last powered up and the state
of the environment it is installed in. Refer to Section
5 Installation
for more information.
6.4 Display Select
After warm up and upon normal operation, the display will cycle through and show a summary of
the status of the gas readings for each enabled channel / sensor. This is the factory default position.
