power output
• All relays circuits are unsupervised. Must be connected only to a power-limited source.
• Alarm and trouble: Form C, 24 VDC at 1 A resistive
• Supervisory: Form A, 24 VDC at 1 A resistive
• Diagram is shown with the panel in a normal state.
Remote annunciator wiring (TB4)
The control panel provides a connection for up to eight remote annunciators.
