• Standard Operation—Relay open.
• Alarm Condition—Relay closed.
Tools required: Ohmmeter.
Step 1 Plug a phono connector into the Nurse Call Relay connector.
Step 2 Connect the ohmmeter.
Step 3 If no alarm occurs, the relay contacts are open.
NOTE When an alarm occurs, the relay contacts close.
NOTE The conditions described above are the unmodified conditions. Please check accordingly if
the Nurse Call Alarm relays have been modified (see “Modification for Nurse Call Alarm
