Output Circuits
Trouble Relay - TB2
The main control board provides a Form-C Trouble relay for independent, general system fault monitoring. This relay is 'fail safe',
meaning that it is normally energized. Should system power shut off, this relay will de-energize, transferring its contacts.
AC Power Loss Relay - TB3
The main control board provides a Form-C AC Power Loss relay.

•
Eight Speaker Circuits Style Z (Class B) or Style Z (Class A) or Style Y with NFC-BDA-25/70V and NFC-CE6
The integral amplifier and optional amplifier each provide audio for one Speaker Circuit. The circuit can be wired Style Y (Class B) or
Style Z (Class A). Each supervised and power-limited (Class 2) circuit is capable of 50 watts of power. Refer to the Notifier Device
Compatibility Document for a listing of compatible speakers.
CAUTION: OBSERVE POLARITY
!
MATCH PROPER POLARITY CONNECTIONS TO FIELD WIRING AND SPEAKERS. POLARITY SHOWN IS IN THE
STANDBY AND ALARM CONDITIONS.
Shielded cable is not required, however, shielded cable will reduce RFI/EMI emissions and susceptibility. For additional information,
refer to "Wiring Requirements" on page 82.
