Nohmi PCA-N3060-SCU expansion control board
Use for Fire Alarm Control Center Switchboard N3060 PCA-N3060-SCU is a microprocessor based circuit assembly equipped with two Signal Line Circuits, Each SLC supports up to 127 or 255 devices. address , The maximum number of devices per loop can be selected using a PC Based Configuration Program. Maximum. 127 devices with 50 ohms loop resistance and 0.5µF loop capacitance are suitable for situations where long wiring is required. Maximum. 255 devices with 25 ohms Loop Resistance and 0.4µF loop capacitance suitable for situations where more equipment is required than long wiring
• UL 864, 9th edition listed
• Max. 127 or 255 addressing devices per SLC
• Two SLCs for each PCA-N3060-SCU
• NFPA Class A (Type 6 & 7) and Class B (Type 4)
• Monitoring status LEDs
• Easy to install
The PCA-N3060-SCU communicates with addressing devices on its SLC and is applicable to class A (Type 6, 7) or Class B (Type 4) NFPA. A green LED on each SLC on the PCA-N3060-SCU blinks while the status monitoring function is working correctly. When the PCA-N3060-SCU detects an abnormal condition, it sends that condition (Alarm, Monitoring or Failure) to the main control unit (PCA-N3060-MCU) via the power supply (PCA-N3060) -PSU) to alert the system operator to this condition.
The Integlex Multicrest N3060 console supports up to 12 SLC
