Example # 1: Combinational Logic
L1D1, L1D2, and L1D3 activate Z1. L1D4 activates
Z2. If Z1 activates, L1M1 will activate. If Z2 activates
then L1M4 will activate. The equation AND(Z1 Z239)
requires both to be active for an output. Because
reverse zone 239 has a NOT operand, it is active as
long as L1D4 is inactive.
Example # 2: General Alarm
L1D1 activates L1M1 through Z1. L1D2 activates
L1M2 through Z2. L1D3 and L1D4 activate L1M4
through Z3. L1M3 will activate when reverse zone
240 is activated. Z240 will activate when Z1, Z2 or Z3
are activated.
Notification Appliance L1M3 serves as the General
Alarm device. It will be activated whenever an alarm
occurs on any addressable initiating device in the
system, due to the fact that all initiating devices
activate a Software Zone, and activation of any zone
activates software zone Z240.
