Key Installation & Commission Steps

1. Pre-Installation Check

1.Verify equipment against packing list (manual, keys, panel components)

2.Inspect panel appearance and internal component connections

3.Test peripheral devices for normal operation

2. Physical Installation

1.Wall-mount the panel in compliance with environmental requirements (temp/humidity)

2.Connect wiring per terminal instructions (AC220V L/N/PE; DC24V 24V/GND; bus/loop/control terminals)

3.Ensure proper grounding (4.0 mm² copper conductor, resistance ≤4Ω)

3. Boot & Initial Test

1.Power on main/standby power; check LCD, indicators, keypad and printer for normal operation

2.Run self-test: Confirm indicators illuminate, speaker emits 3 consecutive beeps

3.Test peripheral wiring: Insulation resistance between bus and ground ＞20MΩ (megger); loop insulation (full load) ≈5KΩ

4. System Commission

1.Encode gas fire-extinguishing detectors/modules per fixed address range (Zone1:1-50, Zone2:51-100, Zone3:101-150, Zone4:151-200)

2.Register loop devices via panel menu; verify registration total/fault/disable counts

3.Set commission mode (to prevent accidental gas spray); disconnect solenoid valves of all zones

4.Conduct detector alarm test and auto linkage experiment; verify logic relation and module function

5.Train operators; switch to normal mode after all tests pass

Key Operation Steps (Common User & Administrator)

1. Basic Operation (Level I, No Password for Basic Functions)

1.oot/Shutdown: Power on peripheral devices → main/standby power (shutdown in reverse; turn off standby power first to protect battery)

2.Self-Test: Press self-test button to test sounder strobes

3.Mute: Press mute to stop alarm sound (invalid for gas feedback pulsing peeps); resets on new alarm

4.Query: Press query to check fire alarm/gas/history records (use ▲/▼/▶ to switch pages)

5.Reset: Input password to clear alarms/faults/indicators (excludes isolation status)

6.Device Disable/Enable: Input device loop/address to isolate faulty devices; restore after

Maintenance

2. Gas Fire-Extinguishing Control

1.Emergency Start:

Evacuate the zone; enable gas button → press "Spray Start" (delayed start) Press "Spray Start" again + Enter to skip delay and start immediately

Alternative: Field emergency start/abort switch; networking panel auto start (zone set to auto)

2.Emergency Abort: Press field stop button or panel "Delay Stop" only during delay period (invalid before delay/after spray)

3.Sounder Strobe Control: Press zone sounder strobe button to start/stop (toggle)

3. Administrator Setup (Level II/III, Password Required)

1.System Setup: Device registration, working mode (normal/commission), loop component definition (2nd code, device type, note)

2.Gas Setup: Set spray delay (0~30s), pulse time (0~99s); factory default: consecutive output, 10s pulse, 30s delay

3.Linkage Program:

Define logic formula (alarm devices → controlled devices) with wildcard *, +(OR), X(AND)

Offline programming: Edit TCLD.txt (linkage) / TCZS.txt (device info) on USB (FAT16, ≤2G), transmit via panel USB port

4.Network Setup: Set as sub-panel; assign local address (1~16) for networking

5.Password Setup: 2/3 level permissions (higher level overrides lower)

6.Factory Default: Erases all field programs (linkage, coding) – irreversible

4. Direct Control Operation

1.Enable direct control buttons; press the corresponding button to send start order

2.Check indicators: Red (start/feedback), Yellow (fault/short/open circuit)

3.Manually start/stop key devices (fire hydrant pump, ventilator) via direct control zone

Common Troubleshooting & Regular Maintenance

1. Typical Fault and Resolution

1. Fault Causes: No/abnormal display

Resolutions: Power fault, display cable disconnection. Check 24V power, re-connect cable

2. Power/battery fault

AC power loss, fuse blowout, low battery. Re-connect AC, replace fuse, change battery

3. Loop comm. fault

Unplugged loop board. Re-plug loop board.

4. No printing

Printer off/cable fault/printer failure. Reset printer, re-connect cable, replace printer

5. Device fault

Disconnection, device damage. Check wiring, replace faulty device

6. Loop control fault

Loop short circuit Inspect and repair the loop

2. Regular Test & Maintenance

1.Cut off solenoid valve connections and set to commission mode before any test

2.Replace printer paper in time; check standby battery voltage regularly

3.Isolate faulty field devices and repair/replace promptly; restore after fault elimination

4.Switch back to normal mode after all tests (system non-functional in commission mode)

5.Keep operation records; contact manufacturer for professional maintenance (no unauthorized disassembly)

Critical Warnings

1.Operate only by trained professional technicians

2.Verify solenoid valve safety with a multimeter before wiring; no violent operation

3.Gas abort is only valid during the delay period (no effect after spray start)

4.Standby power supply time ≤8h; cut off power if exceeded to avoid battery damage

5.Ensure proper grounding to prevent electromagnetic interference
