FC-7601B Single Zone Output Module
1. Product Overview
FC-7601B is a single-zone addressable expansion module designed for FOCUS bus alarm systems, compatible with FC-7668/FC-7688 main controllers. It expands one physical defense zone with a relay output for linkage control, ideal for perimeter security, doors/windows, and alarm device activation.

3. Functional Features
Single-Zone Expansion: Connects one NC/NO detector (door contact, PIR, vibration sensor).
Address Coding: 8 DIP switches set unique address (1–128) for bus communication.
Relay Output: Onboard relay for activating sirens, strobes, or other 12V devices; NO/NC configurable.
Tamper Protection: Built-in tamper switch (anti-disassembly, triggers alarm if opened).
Bus Communication: RS-485 bus, supports long-distance wiring (up to 1500m).
Low Power: Minimal standby current, suitable for battery-powered systems.
4. Wiring Diagram
Terminals:
+V: Power input (DC 8.5–24V)
GND: Ground
A/B: RS-485 bus (A→A, B→B, no polarity)
Z1/Z2: Zone input (connect detector + 10kΩ EOL resistor)
COM/NO/NC: Relay output (COM: common, NO: normally open, NC: normally closed)
TAMPER: Tamper switch (connect to host tamper input)
5. Installation & Setup
Address Setting: Use 8 DIP switches (binary: 1=ON, 0=OFF). Example: Address 9 = 00001001.
Wiring: Connect power, bus, detector, and tamper; use twisted pair for RS-485.
Host Configuration: Add module address to FC-7668/7688; set zone type (NC/NO) and output linkage.
Testing: Power on, verify LED status (green=normal, red=alarm); test relay output.
6. Applications
Perimeter alarm systems (fence,
beam sensors)
Door/window contact monitoring
Alarm linkage (siren, strobe, camera)
Industrial equipment status monitoring
7. Notes
Use 10kΩ EOL resistor for zone line supervision.
RS-485 bus wiring: twisted pair, max 1500m, no polarity.
Avoid high-voltage interference; keep away from power lines.
Operating humidity: <85% (non-condensing).
