7.4.1GENERAL

The F3200 outputs (Ancillary Relays, MAF Brigade Relays, 8 Zone Module open collectors and 8 Relay Module relays) may be programmed to operate on a logic equation of zone and FIP status. Zone LEDs may also be controlled by an output logic equation. Output logic equations may also be used to isolate, de-isolate or reset zones. The Ancillary Relays (including Anc3 /Bells) and the Open Collector outputs each have a default logic equation but the module relays do not. By default, Ancillary Relays and Bells operate on an alarm on any zone mapped to operate that output. By default, open collector output n is active when zone n is in alarm. The LEDs on the 16 zone LED display boards may be controlled by output logic using a relay equation where the relay number is in the range 65 to 256.

The outputs which can be programmed are shown in the Output Logic Menu in Fig 7.1.1 and described in Section 7.4.6.

The logic equation takes the form of:

Output = [operand] operator [operand] operator [operand] ...

E.g. RL1 = Z3A + Z4A means that Module relay number 1 will energise when zone 3 is in alarm or zone 4 is in alarm (or both). Zone 3 alarm and zone 4 alarm are operands (inputs) and the logic operator is OR (+).

Some examples of equations are shown in Section 7.4.4.

Output Logic	: Number of "small" equations	289 maximum
	Number of "()" per equation	14 maximum
	Equation Size (note 1)	100 bytes max
	Number of variables available	256
	Number of network variables	128 per SID
	Number of seconds timers available	64 (1-64)
	Number of minutes timers available	8 (65-72)
	Type of timer (see following)	Stretch/Pulse
	Time range of timers	0-250 seconds/minutes
	Error margin of seconds	0-1 sec plus
	timers 1-64	O/P Logic Time
	Error margin of minutes timers 65-72	0-1 Minute
	Output Logic Processing Time	0-1 second
	(refer to note 2 following)

1.The maximum size of an equation is approximately 30-40 operands plus operators. It is 100 token bytes, where most operands use 2 bytes, and operators use 1 byte.

2.The Controller continually "updates" the status of the inputs to the output logic equations, processes the equations, and updates the resultant outputs. The processing time taken is dependent on the number and size of the equations.

A timer is started by a logic equation, and then operates the output via another logic equation. There is a processing delay added to the timer delay.

For a system with only 10-20 small to medium sized equations, the processing delay should be of the order of 100 msec, and an approximate 1 second timer can be used.

For a system with the maximum number of equations the processing time may delay beyond the 1 second stated, so that a delay programmed as "1 second" would cause a real delay (from input event to output options) in excess of 3 seconds.
