When ordering this product, you must specify
3 codes. These 3 codes will build up a part number.
Codes must be listed in the following sequence:
Code A- Model Number
Code B- Number of Zones
Code C- Input Power Type
For example, to order a 4-zone, 120VAC Ammonia
Monitor, you would order a: AGM300-11-1
Remote Display Modules, options and accessories
must be ordered as separate line items.
