Important Installation Notes
The Max It 900AS is not a plug-and-play system. Professional installation is required. This manual provides general information, but detailed wiring diagrams and specific vehicle installation instructions are typically provided to certified installers. Some vehicles may require additional parts for complete integration.
Ensure that the installation is performed by a qualified technician to prevent damage to the vehicle's electrical system or the module itself.
Setup and Initial Configuration
Initial setup involves physical installation of the module and its components, followed by programming. Due to the complexity and vehicle-specific nature, only a high-level overview is provided here.
Component Placement:
- CM900-AS Controller: Typically mounted securely within the vehicle's dashboard or under the steering column, away from moisture and excessive heat.
- FT-Siren: Mounted in the engine bay, facing downwards to prevent water accumulation, and away from direct heat sources.
- FT-Shock Sensor: Mounted securely to a rigid part of the vehicle's chassis, typically under the dashboard, to accurately detect impacts.
- FT-LED Blue: Installed in a visible location on the dashboard or windshield to act as a visual deterrent.
Wiring and Connections:
All wiring connections must be made according to the specific vehicle's wiring diagram and the CM900-AS installation guide provided to professional installers. This includes power, ground, ignition, accessory, starter, door triggers, trunk trigger, hood trigger, and parking light connections.
Module Programming:
After physical installation, the CM900-AS module requires programming to communicate with the vehicle's immobilizer and other systems. This process often involves specific sequences using the vehicle's ignition key and/or a specialized programming tool. Refer to the professional installation guide for detailed programming steps.
Operating Instructions
The Max It 900AS module functions as the core of your vehicle's remote start and security system. Operation is typically performed via compatible remote controls (sold separately) or smartphone applications (if a DroneMobile module is integrated).
Remote Start Operation:
- Ensure the vehicle is in park and the parking brake is engaged (if applicable).
- Press the remote start button on your compatible remote control (e.g., the key icon or a specific sequence of button presses).
- The vehicle's engine will start, and the parking lights may illuminate to indicate remote start activation.
- To enter the vehicle after remote starting, unlock the doors, insert the key into the ignition, turn it to the ON/RUN position, and press the brake pedal. The engine will transfer control from the remote start system to the key.
- To turn off the remote start, press the remote start button again on your remote, or use the brake pedal if already inside the vehicle.
Security System Operation:
- Arming: Press the lock button on your compatible remote control. The vehicle's doors will lock, and the security system will arm. The FT-LED Blue will typically flash to indicate the system is armed.
- Disarming: Press the unlock button on your compatible remote control. The vehicle's doors will unlock, and the security system will disarm.
- Alarm Trigger: If the security system detects an unauthorized entry (e.g., door opening, shock sensor activation), the FT-Siren will sound, and the vehicle's lights may flash.
- Panic Mode: On most compatible remotes, pressing and holding a specific button (often the lock or unlock button) will activate the siren and lights for emergency signaling.
Maintenance
The Firstech Max It 900AS module is designed for long-term reliability and typically requires minimal user maintenance. However, periodic checks can ensure optimal performance.
- Wiring Inspection: Periodically, or during other vehicle maintenance, have a qualified technician inspect the wiring connections for any signs of wear, corrosion, or loose connections.
- Shock Sensor Adjustment: If the shock sensor (FT-Shock) is too sensitive (false alarms) or not sensitive enough, its sensitivity can be adjusted by a professional installer. This is typically done via a small dial on the sensor itself or through programming.
- Firmware Updates: From time to time, Firstech may release firmware updates for the CM900-AS controller to improve performance or add features. These updates must be performed by a certified installer using specialized tools.
- Remote Control Batteries: Ensure your compatible remote controls have fresh batteries for reliable operation. Refer to your remote's specific manual for battery replacement instructions.
