Abstract
An electromagnetic signal detector with a means for detecting a first electromagnetic signal within a plurality of bands of frequencies, generating an alarm signal in response, and reinitiating an alarm signal for a second subsequent signal in one of said band of frequencies different from said first electromagnetic signal detection, is provided. The alarm signal response can be muted. The audible alarm signal reinitiates at any point in an alarm signal generation, even during muting, if a second subsequent electromagnetic signal of a different frequency band is detected.
