2. Setup
2.1 Powering the System
The LYNX Touch 5210 operates on a primary plug-in power supply, converting 110VAC to 9VDC with a 2.7A output. Compatible power supply models include 300-04705V1 or 300-04065V1 (300-04063V1 in Canada).
A rechargeable nickel-metal hydride battery pack, rated at 7.2Vdc, provides 4 or 24-hour backup power in case of a primary power interruption.
2.2 Connectivity (Optional Modules)
The LYNX Touch 5210 is designed for expandability with optional communication modules:
- Wi-Fi IP Communication: For Wi-Fi connectivity and alarm reporting, the L5100-WIFI Wi-Fi IP Communication Module is required (sold separately). This module supports IEEE 802.11 B/G/N radio and two-way voice.
- Z-Wave Control: For Z-Wave device integration, the L5100-ZWAVE Z-Wave Control Module is required (sold separately). This module supports up to three thermostats, four door locks, 40 devices (lights, switches, lamp modules), 20 scenes, 20 rules, and 20 schedules.
- GSM Cellular Communication: For cellular central station communication, a Honeywell 3GL Communications GSM radio is required (sold separately). This supports AT&T and Rogers networks and offers touch-activated radio registration and signal strength display.
3. Operating the System
3.1 User Interface
The 4.3-inch touchscreen display serves as the primary user interface. It shows the current time, date, and system status. Users can navigate through various functions including arming/disarming, checking zone status, and accessing messages.
3.2 Arming and Disarming
The system can be armed or disarmed directly from the touchscreen interface by entering a user-defined password. The system provides clear visual and audible feedback on its armed or disarmed state.
3.3 Zone Monitoring
The system continuously monitors various zones within your property, such as entry doors, motion sensors, and tamper sensors. Status updates for these zones are displayed on the screen, indicating if a zone is open, faulted, or tampered.
Audible alerts are provided for open doors or detected motion, offering immediate notification and enhancing security awareness.
3.4 Mobile Access
The LYNX Connect app allows remote monitoring and control of the system from up to four mobile iOS and Android devices, providing convenience and flexibility for managing your security from anywhere.
4. Maintenance
4.1 Battery Backup
The system includes a rechargeable nickel-metal hydride battery for backup power. To ensure optimal performance and battery life, keep the system connected to its primary power supply to allow the backup battery to remain charged. Regular checks of the battery status are recommended.
4.2 System Updates
Programming options are stored in EEROM and can be updated or controlled using Compass Downloader software. This requires a specified modem or a compatible communication module (GSM, Wi-Fi, or IP) to facilitate the update process.
5. Troubleshooting
5.1 "Not Ready To Arm - System Trouble" Message
This message indicates an issue preventing the system from being armed. Common causes and solutions include:
- Communication Trouble: If the display shows "103 Comm. Trouble", verify your internet connection if using a Wi-Fi module, or check the GSM signal strength if using a cellular module. Ensure all communication modules are properly installed and configured.
- Faulty Zones: Specific zones may report faults, such as "Fault 1 Entry Door" or "Supervision 11 Motion Sensor". Check the affected door or sensor for proper closure, alignment, or function. Replace batteries in wireless sensors if necessary.
- Tamper Alerts: A message like "Tamper 12 Master Bedroom" indicates a tamper condition, often due to a sensor being disturbed or its cover opened. Inspect the sensor in the specified location and ensure it is securely closed.
5.2 System Reboots on AC Loss
If the LYNX Touch 5210 reboots a few minutes after AC power loss, it may be attempting to establish communication with the central office without a stable communication path. Installing a L5100-WIFI module (sold separately) can resolve this by providing a consistent communication channel, thereby preventing unnecessary reboots during power outages.
