The Digital Output module with relay outputs (Module ID 6) contain jumpers to set the de-energized state
of the relay contacts. The relays are factory set to normally open (NO) for each output on the relay alarm
module, as shown in Figure 18.
To change the state of the contacts: Use a pair of needle-nose pliers and move the jumper from the location
NO (normally closed) to the location NC (normally closed).
