3.5.6 Connecting Alarm Relay Devices to the TB3 Block
Terminal block TB3 contains the connections for the relay contacts for alarm equipment such
as sirens; it is included on an optional circuit board module. The functioning of the Alarm and
Warning relay connections varies depending on whether the relays are configured as
Energized or De-Energized. For more information, refer to Sections 4.6.2 and 4.6.3.
NOTE:
The default TS4000H configuration menu setting for the Warning and Alarm relays is
De-Energized. The Fault relay is normally Energized. It will change state after power-
up.
Use the following table as a guide for determining the Normally Open (NO) and the Normally
Closed (NC) contacts for the Energized versus De-Energized setting.
