COMMUNICATION

8.6Building Alarm Monitoring

This standard feature lets you connect the UPS to your building alarms, such as smoke detectors or overtemperature alarms. The customer interface terminals for external connections are located inside the UPS. You should use twisted−pair wires for each alarm input and common.

The building alarms can be programmed to display the alarm functional name.

8.7General Purpose Relay Contact

One general purpose relay contact is provided as a standard feature on the UPS. The alarm contact is located inside the UPS on the customer interface terminal board.

You can use a normally−closed or normally−open contact. If the state of the contact changes from the state you specify as normal, a signal is issued. You can connect this contact to equipment at your facility (such as a light or an alarm bell) to let you know when an alarm is active on the UPS. This feature is useful if the UPS is located in a remote area where the UPS horn may not be heard immediately.

Contacts should not be operated in excess of 30 Vac @ 5A maximum.

8.8Remote Monitor Panel II

As an option, an Remote Monitor Panel II (RMP II) can be installed to monitor the operation of the UPS system from virtually any location within the facility, up to

150m (500 ft) from the UPS. The RMP II contains backlit status indicators and a local horn. The RMP II can be flush-mounted or surface-mounted on a desktop, or secured to a wall. Figure 8-3shows an RMP II front panel.
