Component
1
FMS-2000M monitor
2
Supplied remote pressure sensors 1, 2, and 3, in order from left to right
3
Optional door switch
Note:
Configure the door switch setting on the monitor. It can be normally closed or normally open.
4
Io terminal
Note:
A 4mA to 20mA signal is present at each of the sensors' Io terminals which represents the monitored room pressure. You can use
it to remotely monitor room pressure when you connect the terminal to a third party controller on the BMS network.
