2.4.3 Relays - Programmable

The MRP-2001control panel provides a factory default programmed alarm relay, fail-safe trouble relay and supervisory relay. Each relay can be programmed to activate for other conditions (refer to "On-Board Relays" on page 64). Each Form-C relay is rated for 2 amps @ 30VDC (resistive) and 0.5 amps @ 30 VAC (resistive).

Note that relay connections must be power-limited.

Note: Relay contacts are shown with power applied to the panel and no active troubles, alarms or supervisories.

The Trouble Relay is a fail-safe relay which will transfer on any trouble or total power failure.
