IQ-301 PN 50036:F 10/29/2001 35
2.5 DC Output Power Connections (TB1)
Figure 11 shows the outputs for DC voltage connections from TB1 on the CPU:
Note: All DC power outputs are power-limited.

2.6 Output Circuits (TB2)
Output circuits include Notification Appliance Circuits (NACs) and releasing circuits
connected through TB2 on the control panel. When connecting output circuits, note the
following:
• Use UL-listed 24 VDC notification appliances only. Refer to the Device
Compatibility Document for a list of compatible releasing devices.
• Circuits are supervised and power-limited.
Figure 12 shows typical connections for NACs and releasing circuits connected to TB2.
2.6.1 Notification Appliance Circuits
The control panel provides four Notification Appliance Circuits (Style Y). Each NAC
can supply up to 2.5 A of current. Total current drawn from these as well as DC power
outputs cannot exceed 5.0 A. An additional 3.0 A are available when using an
expansion power supply (AVPS-24/AVPS-24E or APS-6R). For details on expansion
power supplies, refer to Appendix J “Expansion Power Supplies”.
Non-resettable Power 24 VDC
filtered, regulated, non-resettable
power can be drawn from TB1
terminals 3 (+) and 4 (–).
Four-wire Smoke Detector
Power 24 VDC filtered,
regulated, resettable power
for four-wire smoke detectors
can be obtained from TB1
terminals 5 (+) and 6 (–).
High Ripple Regulated Power
24 VDC power for notification
appliances. TB1 terminal 1 (+) and
2 (–). Note: This power is unsuitable
for all EIA-485 annunciation
devices, except the ACM-8R.
