Description
Honeywell TERMINAL PLATE F860-CA
Technical Specifications Terminal quantity matches system loop requirement; Screw type terminal blocks; Rated operating voltage DC24V; Insulation material flame resistance rating meets fire safety standard; Operating temperature range -20°C to +60°C; DIN rail mounting structure; Marking area for circuit tag identification; Supports shielded cable termination.
Functional Features Centralized termination for multiple fire detector loops; Clear circuit marking area for wiring identification; Physical isolation between adjacent signal channels; Sturdy screw terminals prevent loose wiring under vibration; Simplify field loop testing and disconnection without removing main module wiring; Compatible with Honeywell fire system backplane assembly; Supports single-point shield grounding for field cables.
Application Scenarios Industrial plant fire and gas control cabinet; Petrochemical fire alarm system; Power station fire safety panel; Offshore platform fire detection control unit; Warehouse fire monitoring cabinet; Building industrial fire alarm control panel.
Performance Parameters Terminal contact resistance maintains stable low value; Insulation withstand voltage meets fire safety specification; Terminal screw clamping force remains consistent after repeated wiring operations; Plate structure maintains dimensional stability under temperature fluctuation; Terminal anti-loosening performance adapts to industrial vibration environment.
Material Composition Flame-retardant rigid plastic base plate; Brass terminal conductors with tin plating; Steel terminal clamping screws; Printed marking layer on plastic surface; Insulating partition ribs between adjacent terminal positions; Metal DIN rail snap clip.
Structural Features Flat rectangular plate form; Multiple terminal groups arranged in parallel rows; Each terminal has independent wire entry hole and clamping screw; Separating ribs between terminal positions prevent accidental short circuit; Marking text area above each terminal group; Snap-on clip on back side for DIN rail installation.
Working Principle Field cables from smoke detectors, flame detectors and alarm horns are routed to this terminal plate. Conductive cores of cables are inserted into corresponding terminals and secured by clamping screws. The terminal plate transmits electrical signals between field devices and Honeywell main control modules. Isolation ribs separate different signal loops to avoid cross short circuit. The marking area records loop number and device information for maintenance personnel.
Installation Requirements Mount the terminal plate vertically on standard DIN rail inside fire control cabinet; Separate fire signal cables from high voltage power cables; Use proper wire stripping length for cable core; Tighten terminal screws to specified torque; Implement single-point grounding for cable shield wires.
Precautions for Use Cut off loop power before wiring modification; Do not overload terminal current rating; Check terminal screw tightness periodically in vibration environment; Keep plate surface free of dust and corrosive residue; Do not install in area with explosive gas mixture.
