LM90 Operation

In an alarm condition the LM21-VAS, working in conjunction with a compatible LM90 product or other electronic signalling source, will provide a warning tone, followed by the high quality voice warning. The LM21-VAS is programmed with two standard messages. These messages include warnings that an emergency condition exists and the door opening should be cleared for closure, as well as a message which begins with a warning tone and proceeds with a ten second count down to closure. Custom messages in Spanish and French are available.

A volume adjust is provided on the LM21-VAS, which allows the installer to set the output level to a maximum of 110dB for noisier environments.
