ENTERING EQUATIONS (CONTINUED)
3. When an equation has been entered, check it, and count the number of "(" and the
number of ")" to ensure they are the same.
4. It is recommended that all equations be written on forms (such as in Appendix B)
before they are entered, and then checked against the forms after they have been
entered).
Example
Enter an equation to program module relay 5 to activate if Zones 9 or 10 go into alarm, but
not if Open Collector 4 is active (say open collector 4 drives a status LED and has a logic
equation entered to do this).
The equation is:
R5 = (Z9A + Z10A).^OC4
From the "System Configuration" menu (4), select "Output Logic" (4) followed by "relay" (1).
Use "NEXT" to step onto Relay 5 (R5)
