Installation
2.7.5 Connecting the Trouble Bus
Trouble bus input is designed to receive
trouble signals from any normally-open dry
contacts or open-collector circuit.
2.7.6 Connecting the Accessories Output on the CPS-24
TB2 - Supplies one (1) non-resettable, power-limited (Class 2) 24 VDC circuit and one
non-resettable power-limited (Class 2) 5 VDC circuit available to power external devices. UZC
applications on the 5V connection to the Accessories Output must be within 10 feet (3.658 meters)
of the power supply and should use the supplied cable, P/N 75595. Do not splice or otherwise
extend P/N 75595. Refer to the "Wire Requirements" section of the panel installation manual for all
applications requiring a 24V connection. The wiring must remain within the same enclosure, or it
must be in conduit. Connect wiring with all power sources off.
• 24 VDC (nominal) @ 0.5 A max.
• 5 VDC (nominal) @ 0.15 A max.
Refer to the Device Compatibility Document for compatible devices and notification appliances.
2.7.7 Connecting the Power Supply to AC Power
TB1 (CPS-24) - Primary AC power source - 120 VAC, 50/60 Hz, 5.0A (AMPS-24E uses 220-240
VAC, 50/60 Hz, 2.5A) from line voltage source.
The AMPS-24 requires connection to a separate dedicated AC branch circuit. Follow these
guidelines when connecting the AC branch circuit:
• Label the branch circuit "Fire Alarm".
• Connect the branch circuit to the line side of the main power feed of the protected premises.
• Do not power other equipment from the fire alarm branch circuit.
• Run the AC branch circuit wire continuously, without any disconnect devices, from the
power source to the power supply.
