Timers
Txx[P/Sy:z] where xx = 1 - 64 for seconds timers and 65-72 for minutes timers, P or S
specifies pulse or stretch operation, y is the delay to output on, and z is the output
delay.
Timers allow outputs to be timed from inputs. They all have two time delays associated with
them and can be "stretch" timers or "pulse" timers. The default configuration sets both
delays to zero, and all timers are set to "false" on power up.
A stretch timer (S) follows the programmed input with two programmable delays, i.e., Input
on to Output on, and Input off to Output off.
A pulse timer (P) is initiated by the input with two programmable delays, i.e., Input on to
Output on, and Output "on" duration.
Examples: These examples show a seconds based timer 1-64, but the same logic
applies to the minutes based timers.
1.
T1 [S20:30] = Z1A (Alarm State on Zone 1)
2.
T5 [P30:25] = Z1A
Notes
1.
If the input turns off before the first delay has expired, the timer is reset. Timing will
restart from zero when the input next turns on.
2.
Any changes to the input while a pulse timer output is on will not affect the output.
3.
For a pulse time of 0, the output may or may not momentarily turn on.
THREE LETTER OPERANDS
ACK When the "ACK" key is pressed with the base display selected this returns true for
between 1 and 2 complete passes of all output logic equations.
ALM
True if one or more MAF mapped zones are in alarm.
