Description
The B520 Auxiliary Power Supply Module is a versatile auxiliary power expansion device designed to interface with compatible control panels via the SDI2 bus within the security and surveillance industry. This expansion module features supervision capabilities, ensuring all status changes are reliably communicated to the control panel, ideal for deployment in industrial, commercial, and institutional environments.
Key Features:
– **Device Addressing**: Equipped with address switches for straightforward device addressing.
– **Expansion Capabilities**: The SDI2 Out terminals provide auxiliary power for SDI2 expansion devices like keypads, while the AUX PWR terminals offer additional auxiliary power for devices such as PIR motion detectors.
Functionalities:
– **Supervision Monitoring**: Actively monitors and communicates the following status information over the SDI2 bus:
– Operation Status (Heartbeat)
– Battery 1 (BATT 1)
– Battery 2 (BATT 2)
– AC Input Power (AC)
Indicator Details:
– **Heartbeat Indicator**: A blue LED flashes on and off during normal operation. A steady On or Off indicates a system fault, while a triple flash signifies communication failure.
– **BATT 1 LED**: A green, steady On LED indicates normal battery status, while flashing suggests a low battery. Triple flashing indicates charger failure, and an Off LED means no battery is detected.
– **BATT 2 LED**: Functions similarly to BATT 1 in terms of status indication.
– **AC LED**: A green, steady On LED confirms AC power is operational. A pulsating LED signals a battery test in progress, whereas flashing indicates low or failed AC power.
– **Battery Charging**: Ensures that fully charged batteries connected to the battery terminals maintain power continuity for the B520 in case of AC power failure.
