We are installing a radio fire-alarm master box on a 1990 (aprox) ESL 1500 fire alarm control panel.
The existing local energy master box is connected through two sets of form c relays and a set of terminals marked "supervised devices." or something similar.
Is anyone familiar with the supervisory circuit in this panel? I am wondering if I need to put a resistor across the supervisory terminals after the master box circuit is removed. Or will a jumper across the two terminals be OK?
Of course, the original manuals are not with the system!
