Miscellaneous Releasing Applications
The outputs are each set to a code appropriate for one of the three releasing phases: for example,
one code for the first alarm, a faster code when the Delay Timer activates, and a continuous tone
during releasing.
Program Program releasing zone ZR1 as follows:
ZR1 = Delay Time:15, Abort Switch:ULI, Cross Zone:YES, Soak Time:120
Map ZR1 to all inputs and outputs shown in this example.
Program logic zones as follows:
ZL1 = AND(OR(L1D1,L1D2,L1D3,L1D4,L1D5,L1D6),NOT(L1M30))
When conditions are met for ZL1, a first alarm has occurred in the releasing zone, but the
Delay Timer has not yet started. Map ZL1 to an output set to the code chosen for a first alarm
(L1M31 in this example).
ZL2 = AND(L1M30,NOT(L1M20))
When conditions are met for ZL2, the Delay Timer has started, but releasing has not begun.
Map ZL2 to the output set to the code chosen for when the Delay Timer activates (L1M32 in
this example).
ZL3 = OR(L1M20)
When conditions are met for ZL3, the 120 second releasing operation has begun. Map ZL3 to
the output that produces a continuous tone (L1M33 in this example).
Program output Type Codes as follows:
L1M20 = RELEASE CKT, L1M30 = INST RELEASE, L1M31 = CONTROL, L1M32 = CONTROL, L1M33 = CONTROL
