(UL 864: 49.8)

When multiple input signals are received from more than one smoke zone 
to initiate different automatic smoke-control sequence(s), the smoke-
control system shall continue automatic operation in the mode 
determined by the first signal received.

Once a floor-based smoke alarm is activated, the system will react as if 
that is the only alarm and will ignore all subsequent alarms, The supply, 
return and stair shaft smoke alarms are still allowed to affect the supply, 
return and stair shaft supply fans. Any reaction can be overridden at the 
smoke control panel.

To ignore all subsequent floor alarms, the program fragment in Figure 53 
on page 102 has been tested and works correctly. Once an alarm is 
triggered by any floor-based smoke alarm, it will be the only smoke alarm 
reaction allowed. When the first alarm is received, it triggers two events; 
it writes the floor of the smoke alarm to analog variable 1 and sets a 
binary variable to hold the output at that value. That binary variable is 
held until all alarms are cleared by the fire smoke control system.
