NOTE: External connections to the pcboard should be made by acquiring locking harnesses for Modem

connections (J13) and External 12V power (J11), Pulse input (J14) & (2) Pulse outputs (J10).

Contact Heath Consultants customer service to get these harnesses.

* JP1: This jumper switches the lithium power from the pcboard circuit.

* JP5: When using the internal 2400 baud modem, a special harness is required for “Call out upon alarm”

feature. This harness connects Pin 2 of JP5 to Pin 6 of J13 (External modems that stay online 100%

doesn’t require this option).
