INSTALLATION WARNINGS AND NOTES
Control and isolator modules use a latching relay that can change states if it is subjected to mechanical shocks or jarring. As a
result, although modules are shipped with their relays in the open state, the contacts may have closed during shipment. Con-
necting an auxiliary control circuit to closed relay contacts in a control module can cause an unexpected, and possibly danger-
ous, activation of that circuit. Therefore, do NOT connect an auxiliary control circuit to the relay contacts before ensuring that
they are in their open (standby) state. Make sure that the contacts are open by allowing the control panel to poll the module at
least once, as indicated when the LED blinks.
If the contacts of several isolator modules are closed when system power is initially applied, it increases the load on upstream
modules, causing their relays to open. This prevents the proper application of power to the entire system. To correct this, con-
nect a temporary jumper between terminals 2 and 3 on all isolator modules whose LEDs are continuously lit OR interrupt the
signal line circuit after the last open isolator. The panel must delay communications for at least one minute after power is ap-
plied to allow all system devices to power up past the 7 volt threshold.
