5520-N5产品概述
Edwards D2 Class devices are low current, high
performance, high decibel audible signals which
may be coded from an external source or used as
a continuous alarm. They are designed to function
as either a horn or siren by setting an internal,
tamper proof switch.
The 5520D is primarily intended for use in
applications requiring electrical supervision of
signaling circuit field wiring. These signals may
also be used for unsupervised signaling
applications.
