Output Relays

Output relays for Alarm, Trouble, Supervisory, and Security are available on power supply
terminals TB8, TB9, TB10, and TB11 respectively.
Contact ratings: 2.0 A @ 30 VDC (resistive)

Four-wire Smoke Detector Power

Control Panel terminals TB7 RESET (+) and (–) supply filtered, low-noise power for four-wire
smoke detectors. Specifications are:
• Nominal voltage: 24 VDC
• Maximum rated current: 1.25 A DC
• Maximum ripple voltage: 176 mVrms
Refer to the Device Compatibility Document for compatible 24 VDC detectors.

Power Output

Control Panel terminals TB7 NONRST (+) and (–) supply one (1) power-limited circuit available
to power external devices, such as notification appliances and annunciators.
• Nominal voltage: 24 VDC
• Maximum rated current: 1.25 A DC
• Maximum ripple voltage: 176 mVrms
Refer to the Device Compatibility Document for compatible devices and notification appliances.
NOTE: The Control Panel provides a total of 6.0 A of power in alarm (3 A in standby), shared by
all internal circuitry and external provisions (24 V resettable and non-resettable). For power
requirements, refer to the power supply calculation tables in Appendix A.
