34 VMA1400 Series Overview and Engineering Guidelines Technical Bulletin
The differential pressure sensor is part of all VMAs (1410, 1420,
1430). The damper actuator is part of the VMA1410/1420. A separate
damper actuator is required for a VMA1430. VMAs cannot share
room sensors.
Dual duct applications require one additional damper actuator and
differential pressure sensor. The actuator M9104-AGS-2N is a
combination of these components.
If VMAs are installed on an N2 Bus connected to an NCM, the NCM
requires a minimum of 4 MB of memory.
2. Coordinate parts ordering and delivery, including:
• placing orders through Johnson Controls Customer Service
• determining shipping destinations
• coordinating VMA manufacturing and delivery issues
• coordinating box manufacturer issues
• coordinating boxes with VMAs delivered to job
• determining status of software, documentation, and
drawings
Note: The VMA can be shipped in individual packages or bulk
shipped (maximum 10 VMAs per box). Separate product codes define
your order preference.
