Extra Alerts
Extra alerts such as horns and bells provide signaling in large, open areas (for example,
warehouses and parking lots) and especially noisy environments. Extra alerts connect either
directly to the Services Module on the control unit or by the Extra Alert Switch.
Extra Alert Horn: Provides a loud
signal in noisy environments where
a unique, non-bell sound must be
heard over a large area. It can be
used indoors or out.
Extra Alert Bell: Alerts people
that a telephone is ringing by
providing a loud signal in remote or
noisy areas. It can be used
indoors or out.
Extra Alert Switch: Connects two
extra alerts. Turns alert signals on
and off (if an alerting device is
connected to only one jack) and
selects between alternate signals,
for example an alert strobe during
business hours and an alert horn
at night (if alerting devices are
connected to both device jacks). A
Line Bridging Adapter inserted into
either device jack permits
connection of a second alerting
device to that device jack.
Jack: Connects to Services
Module of control unit.
