8. Working Principle

1. Bus Signal Receiving Phase: The IDNet fire bus from Simplex 4100 main control panel transmits digital coded commands and system power supply to 4100-3102 module; internal bus transceiver circuit isolates and decodes bus digital signals to extract address matching instructions for the module.
2. Input Signal Collection Phase: External field equipment dry contact feedback wiring connects to supervised input terminals; internal constant current supervision circuit continuously detects input loop resistance value, resistance abnormal fluctuation caused by open or short wiring triggers fault identification circuit and generates fault coded data to feed back to main panel via communication bus.
3. Output Control Execution Phase: After receiving valid startup/shutdown command matching its pre-set address from main controller, internal MCU drives built-in Form C relay coil to complete contact pull-in or release action, realizing external load equipment circuit switching via relay dry contact terminals.
4. Status Feedback Loop Phase: Real-time working status of relay output is synchronously sampled by internal detection circuit, all normal, fault and actuation status data is periodically uploaded to Simplex 4100 host for real-time system status monitoring and event log storage.

12. Installation Requirements

1. Install location requirement: Indoor dry, ventilated non-explosive ambient environment; prohibited for installation inside high-temperature boiler room, high-humidity underground pool room and corrosive gas concentrated equipment room.
2. Mounting fixation mode options: DIN35 standard top-hat rail clamping installation inside fire control junction box or direct screw fixed mounting on flat insulating mounting plate.
3. Wiring specification requirement: System IDNet communication bus must adopt twisted pair fire-resistant copper cable with cross-sectional area ranging 1.0mm²~2.5mm²; external input/output control wiring shall use 0.75mm²~2.5mm² insulated fire-proof control cable.
4. Installation spacing requirement: Minimum 15mm clearance space reserved around module housing for natural heat dissipation, multiple adjacent modules installed with ≥10mm gap between each casing.
5. Enclosure installation environment: When installed inside field wall-mounted junction box, junction box internal usable volume must exceed 3 times the module overall volume to avoid heat accumulation.
6. Grounding specification: Module internal functional grounding terminal must connect to fire system dedicated protective earth ground bus with independent grounding wire, prohibited shared grounding wire with power distribution cabinet strong current circuit.

13. Operation & Usage Precautions

1. Strictly prohibit connecting external AC high voltage load exceeding relay rated contact parameter to module output terminals; over-rated load connection causes permanent relay contact burnout and module failure.
2. All wiring construction must complete under full power-off status of Simplex 4100 main panel and module bus power supply; live wiring leads to internal circuit board component breakdown.
3. Avoid direct liquid splashing, dust accumulation and chemical solvent corrosion on module outer casing during long-term site operation; regular quarterly dust cleaning via dry lint-free cloth only, no liquid detergent cleaning allowed.
4. Any module address modification operation must be finished via authorized Simplex 4100 system qualified operator with system programming access permission, random address tampering results in entire system linkage logic disorder.
5. If inductive loads such as AC contactor coils are connected to output terminals, auxiliary freewheeling surge absorption diode must be installed in parallel at load terminal as external surge protection per factory specification.
6. Storage of spare unused modules requires sealed packaging storage under 10°C~35°C dry environment, prohibited long-term open-air placement under high temperature and damp outdoor environment.
7. In case of module permanent fault damage during usage, only original Simplex factory replacement part is allowed; third-party refurbished or substitute modules cannot access into certified 4100 fire alarm system for formal engineering operation.
