Nfc-Loc Local Operator Console - Honeywell NOTIFIER NFC-50/100 Instruction Manual

Installation

2.7 NFC-LOC Local Operator Console

CAUTION: EXTERNAL WIRING CONNECTIONS
!
THE NFC-LOC IS A SEPARATE DEVICE, NOT PART OF THE NFC-50/100 ASSEMBLY!
Wiring for the Local Operator Console is accomplished between TB24, TB12, and TB22 on the NFC-50/100 main control board to TB3,
TB4, and TB5 on the LOC. If the NFC-LOC is the last device on the audio and data bus chain, signal terminations are required. For the
external data bus, a removable jumper must be on pins 1 and 2 of JP2 when the LOC is the last device on the chain. If the NFC-LOC is
not the last device, the jumper must be on pins 2 and 3 of JP2 as shown below. For the external audio riser, when the LOC is the last
device, termination ELR-15K must be connected to pins 5 and 6 on TB5. T-taps and multiple home runs to the main control board are not
allowed for the external data bus or the external data riser.
