Variant Options for SKYRS (Pakistan Market)
The VP-2241 core amplifier architecture is adapted for Pakistan’s specific commercial and industrial infrastructure projects through the following regional system variations managed by SKYRS:
VP-2241 Standard System Variant: Combined with the VP-200VX module for standard PA and EN 54-16 compliant Voice Evacuation systems.
VP-2241 BGM System Variant: Combined with the VP-200VX-BGM module, allowing dedicated background music inputs for retail, hospitality, and corporate environments.
VP-2241 Dual Backup Configuration: Tailored for critical infrastructure deployments in Pakistan (e.g., airports, metro stations) where the system is configured exclusively as a standby hot-swappable amplifier to step in automatically during a primary channel failure.
Deployment and Installation Guide
Physical Mounting
The unit comes supplied with 4 rack-mounting screws and fiber washers.
Fix the amplifier firmly into a standard 19-inch equipment rack. Ensure 1U of empty ventilation space above and below the unit if stacking multiple high-power amplifiers to preserve cross-flow air efficiency.
Wiring Connections
DC Power Input: Connect the 28 V DC operating line to the heavy-duty M4 screw terminals. Ensure proper polarity to avoid protection trips.
Speaker Line Output: Connect the distribution speaker network to the M3.5 screw terminals. Ensure the combined total wattage of all tapped speakers does not exceed the 240 W ceiling.
Configuration and System Calibration
Output Voltage Selection: The amplifier defaults to 100 V line distribution. If your localized field deployment requires 70 V or 50 V speaker lines, the internal configuration wiring must be switched by an authorized engineer prior to powering on.
Module Insertion: Insert the VP-200VX or VP-200VX-BGM module securely into the rear slot before system initialization to establish link supervision with the main controller.
Standby Mode Programing: Configure the programmable standby delay via your primary system controller interface (such as the VM-3000 master). This minimizes battery drain during power outages, dropping current consumption down to a mere 0.03 A, with an automatic wake-up time of less than 0.5 seconds when an audio signal or emergency trigger is detected.
