Simplex 4010 Applications Manual

A-4
Some application-specific needs can also be met without Custom Control simply
by using the correct point types. A point’s type determines the following:
• The message displayed on the 4010’s LCD when changes occur to the state
of the point’s circuit.
• The way in which the system operates (for example, initiate an Alarm,
Trouble, or Supervisory action) when changes occur to the state of the
point’s circuit.
AHU off relay – dual relay control. This point type is used with applications
that use two auxiliary relays for AHU control – one relay for ON and one relay
for OFF. Use this point type for the OFF relay. Points assigned with this type
operate on general alarm (that is, when any point within L1 “General Alarm
List” goes into alarm). Point turns OFF on Reset.
Stagger Start functionality for air handler units is provided by the “Stagger
Start” system option.
See AHUO for the ON relay point type. If you have a single relay that performs
both ON and OFF functions, see AHUR.
