CONNECTION TO AN EXTERNAL ALARM
The Model 640 has a 6-pin FAULT connector for interface to an external alarm system. The male
Weidmüller connector provides 3 usable signals from an onboard relay. The fault interface
signals terminal failure conditions to the connected equipment. This is useful in applications
where the correct paging operation is critical, such as emergency response and nuclear plants.
Use the pinouts shown in Table 14 to create an appropriate cable for the FAULT connector.

Pin # FAULT Output Signal
1 Relay normally closed (NC)
2 Relay common (COM)
3 Relay normally open (NO)
