Note that it’s crucial to verify that the ADEMCO control panel is compatible with V-Plex devices before installing the 4208U.
Understanding V-Plex Technology
V-Plex technology, employed by the ADEMCO 4208U, represents a sophisticated approach to security system communication. It allows for the multiplexing of multiple zones over a single pair of wires, significantly reducing wiring complexity and installation time. This polling loop system continuously monitors the status of each connected device.
At its core, V-Plex uses a unique serial number assigned to each device, enabling the control panel to identify and communicate with each zone individually. This method provides enhanced security and supervision compared to traditional hardwired systems. The technology also supports tamper protection.
Moreover, V-Plex offers the flexibility to assign any serial number to any zone number, streamlining system configuration. Loops A and B of the 4208U can be programmed for a fast (10msec) response, catering to applications requiring immediate alarm reporting. Understanding V-Plex is crucial for efficient use.
V-Plex technology uses less current than other systems.
Installation and Setup
Proper installation and setup of the ADEMCO 4208U are crucial for optimal performance. This section details mounting, wiring connections for polling and protection loops, and correct DIP switch configuration.
Mounting the 4208U Module
Before initiating any wiring procedures, ensure that the ADEMCO 4208U module is securely mounted. For remote installations, tamper protection is essential. The housing features holes on the back, enabling mounting via screws. Wires can be routed through the sides or the rear breakout of the housing.
To activate tamper protection, set DIP switch 8 to OFF and attach the provided tamper magnet to the inside cover of the module. If the cover is removed, the magnet will trigger a tamper signal for each active zone on the 4208U.
When mounting the module inside the control cabinet, ensure it is oriented horizontally and secured with screws utilizing the provided slots on the back. Tamper protection is not required in this scenario, provided the cabinet itself is supervised. Always disconnect power prior to mounting. For CE installations, follow ADEMCO N6361 EMI suppression instructions for proper wire routing.
Wiring Connections⁚ Polling Loop and Protection Loops
Establish secure wiring connections for both the polling loop and protection loops. Wires can be fed through either the back or front of the unit after removing the appropriate knockouts. Employ 22-gauge twisted pair wire specifically for the polling loop connections, ensuring reliable communication with the ADEMCO control panel.
All protection loops necessitate the use of 10k EOL (end-of-line) resistors, which are included with the module. Maintain a maximum resistance of 300 ohms on protection loops, excluding the EOLR. Refer to the wiring diagram for detailed connection guidance.
Note that connections to the polling loop are mandatory for proper module operation. Power supply connections, however, are optional and may be utilized to reduce the current draw from the polling loop. For commercial fire applications, external power supplies are strictly prohibited. Ensure all connections are compliant with relevant safety and regulatory standards.
DIP Switch Configuration⁚ Zone Assignment Mode
In Zone Assignment Mode, the DIP switches are crucial for assigning the 4208U to a group of eight consecutive zones. These designated zone numbers are exclusively reserved for the 4208U and cannot be utilized for any other purpose, even if all eight loops are not actively in use.
To configure the DIP switches in this mode, carefully follow the steps outlined in Table 1 of the installation manual. It is essential to set DIP switch position 6 to “OFF” for Zone Assignment Mode to function correctly. When using this mode, program each zone’s Input Type as “DIP Switch Polling Loop Device (DP)” within the control panel’s programming interface, where applicable.
This particular switch setting predefines the loops to specific zone numbers. Note that Zone Assignment Mode should be employed only on panels that support this configuration method.
Consult the control panel’s installation instructions for specific programming requirements and compatibility information.
DIP Switch Configuration⁚ Serial Number Mode
In Serial Number Mode, the DIP switches are configured to assign the 4208U to a specific group of eight serial numbers. This mode offers flexibility, allowing each serial number within the selected group to be assigned to any available zone number, excluding the control panel’s hardwired zone numbers.
A significant advantage of Serial Number Mode is that you do not lose zone numbers even if you do not utilize all eight loops on the 4208U. To configure the DIP switches correctly, refer to Table 2 in the installation manual and follow the provided steps meticulously.
When programming the control panel, each zone must be programmed as “INPUT TYPE 6 –SL (Serial Number Polling Loop Device).” Loops can be learned in any sequence and assigned to any legitimate zone number. During the serial number learning process for a particular zone, you can either manually enter it through the keypad, use the COMPASS Downloader software, or learn it by momentarily faulting (shorting) the terminals of that zone.
Programming and Configuration
Proper programming and configuration of the ADEMCO 4208U are crucial for optimal performance. This includes setting up zones in serial number mode and configuring tamper protection features.
Programming Zones in Serial Number Mode
When utilizing the serial number mode for programming zones on the ADEMCO 4208U, each zone must be configured as INPUT TYPE 6, designated as SL (Serial Number Polling Loop Device). This configuration allows for the assignment of a unique serial number to each of the eight available zones on the expander module.
Loops can be learned in any order, granting flexibility in assigning them to any legitimate zone number within the system. This process involves either manually entering the serial number via the keypad or utilizing the COMPASS Downloader software. Alternatively, the serial number can be learned by momentarily faulting (shorting) the terminals of that specific zone, as dictated by the control panel’s requirements.
The DIP switches on the 4208U are instrumental in assigning the unit to a group of eight serial numbers, offering a streamlined approach to zone configuration. This method ensures accurate identification and monitoring of each zone connected to the expander module, enhancing the overall security system’s effectiveness.
Tamper Protection Setup
For enhanced security, the ADEMCO 4208U offers tamper protection capabilities that can be configured via on-board DIP switches. This feature is crucial for installations requiring a high level of security, particularly in commercial settings. Enabling tamper protection ensures that any attempt to compromise the module’s integrity triggers an alarm signal.
To activate tamper protection, set DIP switch 8 to the OFF position. Additionally, attach the provided tamper magnet to the inside cover of the module, positioning it near the reed switch. When the cover is removed, the absence of the magnet will cause the reed switch to trigger a tamper signal.
Ensure the control panel is programmed to recognize the tamper zone. If the module’s cover is removed, the magnet attached to the cover will cause a tamper signal to be sent to the control for every active zone on the 4208U module.
