Alarm, trouble, and supervisory relay (TB3)
The trouble relay is normally-open, held closed,
and opens on any trouble event or when the
panel is de-energized. The supervisory relay is
normally-open, and closes on any supervisory
event. The alarm relay changes over on any
alarm event.

Relay circuits can only be connected to power-limited sources.
Auxiliary & smoke power outputs (TB3)
The control panel provides two auxiliary power
outputs that can be used for powering ancillary
equipment such as remote annunciators and two
wire smoke detectors. Aux 2 can be software
selected to operate continuously. The circuit is
supervised for shorts and grounds.

Continuous circuit
(Aux power 1)
24 VDC nominal at 500 mA.
Use this circuit for powering
two-wire smoke detectors.
Note: Any current above 0.5 amp connected to both Aux
1 and 2 will reduce the total available NAC power by that
amount.
Notification appliance circuits (TB2)
VS4 control panels come equipped with four notification appliance
circuits. VS1 control panels come with two NACs. Each circuit can
be individually configured for continuous, temporal, synchronized,
and coded output.

Marking indicates output signal polarity when the circuit is active. Polarity reverses
when the circuit is not active. Wire notification appliances accordingly. Notification
appliance polarity shown in active state.
