ALIU Options Settings
The default settings are the Pin1 to Pin2 connections in all cases up to J20, except for J3 and J10/J16.
J11 and J12 (Opto-coupler Input Voltage Options) are only used for systems with a 24 Vdc source or
reference the Battery Return on P2 and P4 of J11. The defaults for J11 and J12 are therefore OUT. If
the J11 or J12 defaults are to be changed, you must order the jumpers separately (order code
A0292488) and install them (maximum of nine jumpers).
J21 to J29 are used to control the alarm output signal. The default settings are:
pin 3 to pin 2 for J21, J22, J24, J25, J27, and J28
-
- pin 1 to pin 2 for J23, J26, J29.
The opposite settings for all of these pins result in alarm condition from a contact opening, i.e., loss of
signal.
