ASENWARE · transmitter-AW-D121
The Asenware AW-D121 is an addressable power transmitter (also referred to as a power supply module) designed to provide stable, supervised power to auxiliary devices within an addressable fire alarm system. Product Overview The AW-D121 is used to provide external 24VDC power to devices that require more current than the communication loop can provide, such as sounders, strobes, or heavy-duty modules. It is an addressable unit, meaning the main fire alarm control panel can monitor its status (such as power failure or battery trouble) directly via the signaling line circuit (SLC). Key Features Status Monitoring: The control panel can monitor the real-time status of the power supply, including AC power loss, battery fault, or output failure. Automatic Charging: Features a built-in intelligent charging circuit for backup lead-acid batteries. Fault Protection: Equipped with short-circuit and over-current protection to prevent damage to the connected devices or the transmitter itself. Addressable Reporting: Occupies a single address on the loop to report its health status back to the main
