3.6.2 Trouble Relay - TB1
The main circuit board provides a Form-C Trouble relay, for independent monitoring, rated for 2.0
amps @ 30 VDC (resistive) and 0.6 amp @ 30 VAC (resistive). This relay is ‘fail safe’, meaning
that it is normally energized. Should system power shut off, this relay will deenergize, transferring
its contacts. The Trouble Relay can be programmed to track the AC Loss Relay and transfer on AC
loss conditions or ignore AC loss conditions (refer to switch 8 in Table 2.3 on page 34).

3.6.4 Notification Appliance Circuit (Speakers)
Each Amplifier Module provides one Notification Appliance Circuit for speakers. The circuit can
be wired Style Y (Class B) or Style Z (Class A). Each supervised and power-limited circuit is capa-
ble of 25 watts of power. The maximum total capacitance for each speaker circuit cannot exceed
250 uF. Refer to the Fire•Lite Device Compatibility Document for a listing of compatible speakers.
