Alarm System Compatibility
The WP05 is intended for connection to a compatible hardwired alarm control panel siren output. The available specifications do not state its operating voltage or exact current draw, so these requirements must be confirmed before connection.
This is a panel-powered wired siren and cannot operate as a standalone or wireless warning device.
Recessed Ceiling Installation
The siren body is recessed into the ceiling so only the low-profile face remains visible. The listed product size is approximately 73 mm in diameter × 55 mm deep; however, the original specifications note that dimensions may vary. Confirm the current product dimensions, ceiling cavity and cable access before cutting the mounting opening.
High-Output Internal Warning
