11.2Building Alarm Monitoring

This standard feature lets you connect the Switchboard System Bypass Module (SSBM) to your building alarms, such as smoke detectors or overtemperature alarms. The terminals for external connections are located inside the SSBM on the customer interface panel.

Regardless of how you assign the building alarms, they display as Building Alarm 1, Building Alarm 2, Building Alarm 3, etc., on the LCD screen of the Monitor Panel. You should use twisted pair wires for each alarm input and common.

If the SSBM is equipped for a Powerware Sync Control, Hot-Tie Control, or continuous duty static switch, not all Building Alarms will be available for customer use. See Appendix A, Drawing 164201373---4 for affected areas.

If the SSBM is equipped with an optional System Maintenance Bypass (SMB), not all Building Alarms will be available for customer use. See Appendix A, Drawing 164201373---4 for affected areas.

11.3General Purpose Relay Contacts

Two general purpose relay contacts are provided as a standard feature on the SSBM. The alarm contacts (one notice and one alarm) are located inside the SSBM on the customer interface panel. Refer to drawings 164201373---4 and 164201373---13 in Appendix A for location of the customer interface panel and for terminal wiring information.

You can specify that each contact be either normally closed (NC) or normally open (NO). If the state of the contact changes from the state you specify as normal, an signal is issued. You can connect these contacts to equipment at your facility (such as a light or an alarm bell) to let you know when an alarm is active on the SSBM. This feature is useful if the SSBM is located in a remote area where the SSBM alarm horn may not be heard immediately.

NOTE: In choosing contacts, note that Relay 1 is normally deenergized and is only energized for an alarm condition. Relay 2 is normally energized and is only deenergized for an alarm condition.

CAUTION:

Contacts should not be operated in excess of 30 VAC or 42.4V peak AC or DC @ 1A maximum.
