SETTING REMOTE ALARM OUTPUTS
The Medical IntelliSwitch™ is designed to interface to an external alarm system. Relay contacts are
brought out through a connector on the bottom of the cabinet. The pin connections on this connector
are set to connect directly to a CONCOA alarm. CONCOA alarms are designed such that the
contacts are Normally Closed (N.C.). In an alarm condition these contacts will open. This is the
factory default. It is possible to change any of these contacts to Normal Open (N.O.) Figure 13
shows the location of the jumpers on the Control Board. To change a contact from N.C. to N.O.
follow the steps below:
1. Turn AC Power OFF to the system
2. Open front door by loosening the 4 screws holding it to the cabinet.
3. Locate the jumpers on the Control Board.
4. Using Table 7 and Figures 12 and 13 set the jumpers.
5. Close door and re-secure it to the cabinet.
6. Make the necessary connections to the alarm and plug the alarm cable into the alarm
connector on the bottom of the cabinet.
7. Turn AC power ON.
8. Test Mode may be used to test the alarm installation.
