Output Relays (common)
Output relays for Alarm and Trouble are common on TB4; Supervisory, and Security are program-
mable on TB5. See Figure 3.11, "Form-C Relay Connections" on page 27).
Contact ratings: 2.0 A @ 30 VDC (resistive)
Four-wire Smoke Detector Power
Control Panel terminals TB10 RESET (+) and (–) supply filtered, low-noise power for four-wire
smoke detectors. Specifications are:
• Nominal voltage: 24 VDC special applications.
• Maximum rated current: 1.25 A DC
• Maximum ripple voltage: 176 mVrms
• TB10 and all 4 NACs share a maximum of 3.0 A in standby and 6.0 A in alarm.
Refer to the Device Compatibility Document for compatible 24 VDC detectors.
Power Output
Control Panel terminals TB10 NONRESET (+) and (–) supply one (1) power-limited circuit avail-
able to power external devices, such as notification appliances and annunciators.
• Nominal voltage: 24 VDC regulated, special applications, 1.5 A max.
• Maximum rated current: 1.25 A DC
• Maximum ripple voltage: 176 mVrms
• TB10, TB2, and all 4 NACs share a maximum of 3.0 A in standby and 6.0 A in alarm.
Refer to the Device Compatibility Document for compatible devices and notification appliances.
NOTE: The Control Panel provides a total of 7.4 A of power in alarm (3.9 A in standby), shared
by all internal circuitry and external provisions (24 V resettable and non-resettable). TB10 and all
4 NACs share a maximum of 3.0 A in standby and 6.0 in alarm. For power requirements, refer to
the power supply calculation tables in Appendix A.
