One Form-C dry contact alarm relay is provided in the
basic panel for controlling supplementary devices. It is
rated 2 amps at 30 VDC and 0.5 amps at 30 VAC
(resistive), and non-silenceable when an alarm occurs.
See Figure 2.4 for terminal location.

One Form-C dry contact trouble relay is provided in the
basic panel for controlling supplementary devices.
It is rated 2 amps at 30 VDC and 0.5 amps at 30 VAC
(resistive) and will silence when the trouble condition is
cleared.
Note: Any power connected to these relay contacts must
come from a power-limited supply. Power may be
obtained from TB1 Terminals 1-2, TB1 Terminals 3-4,
TB2 Terminals 1-2, or a UL-listed power-limited supply.
