摘要：
An output device emits alarm indicating light and sound at predetermined levels when activated. The device enters a test mode in response to received test mode indicating control signals. When the device is in the test mode, and a local test initiating control signal is received, audio and/or visual outputs are emitted at a level reduced from the alarm indicating output levels to test those outputs.
