LD A93, Indoor Siren

Device Description — LD A93

LD A93 is a compact indoor siren designed for security alarm systems. Its small form factor and sufficiently high sound output make it suitable for discreet alarm signalling inside buildings.

Main Features

• Supply voltage: 12 volts DC
• Sound level: approximately 110 decibels
• Current consumption: roughly 150–250 milliamperes (depending on version)
• Dimensions: small mini-format enclosure
• Housing: plastic, intended for indoor installation
• Mounting method: surface-mounted
• Flash: none — this is an audio-only siren without a visual indicator

Notes

• LD A93 is designed for indoor alarm systems where a compact, unobtrusive siren is preferred.
• Not suitable for outdoor use, as it is not weather-resistant.
• A stable twelve-volt DC power source is required for reliable operation.
• Its compact size makes it easy to install in confined spaces, such as technical cabinets or near the alarm control panel.
