How to Program a Release Code Bell Circuit
When coded ouput is desired to indicate different phases of a releasing operation, the panel can be
programmed using Control-By-Event (CBE) to turn on outputs set to provide the chosen codes.
In the following example, programming is shown that will
1.
Turn on an output when the first alarm activates in a releasing zone, but Cross Zone
conditions are not met. Turn it off when the Delay Timer starts.
2.
Turn on a different output when Cross Zone conditions are met and the Delay Timer
activates, and turn it off when releasing starts.
3.
Turn on a different output when releasing starts, and turn it off when the system is reset.
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 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).
