a alert notification system, emergency management professionals must
consider the special needs of some citizens, and the radio signal
strength within some structures. With WSI option devices, your citizens
are better equipped to receive an emergency notification.
This product is developed to alert the hearing impaired, as well
as people in a noisy environment. A single tone alert receiver
can activate multiple strobe lights throughout a house, so the
resident sees a strobe flash wherever he/she may be. This sub-system
may be integrated with other existing residential systems (e.g.,
This backlit LCD accessory displays the
text of the emergency message. As with the strobe
light, the text display’s internal
backup batteries are continuously trickle charged.
Public Address Systems
OnAlert receivers include the ability to provide line out audio in existing
public address systems found in many high-occupancy facilities. The PA system
further broadcasts the emergency notification within the facility.
The OnAlert’s excellent radio signal is well suited
to most facilities. However, in buildings having extensive metal
or in fringe-covered areas, an external antenna with a pre-amplifier
(available from WSI) helps ensure reliable signal reception.
The vibration-alerting device is for the person who is
hearing and/or vision impaired. The vibrator is placed in a person’s
bed or chair, for example, and is activated by the tone alert receiver.
ONALERT’s EAS Front-End receives all notifications for a
state or county as designated by the FIPS code. The ONALERT system
then broadcasts these notifications - with local control - over
the customer’s designated frequency to the tone alert radios.
External Relay Module (ERM)
ERM connects to a Warning Systems Tone Alert Radio (TAR) to enable
activation of external devices such
as lamps, buzzers, and
bells, and for providing isolated receiver audio to an external
amplifier or public address (PA) system. It is primarily intended
for activating devices other than Warning Systems’ proprietary
alerting units such as the external strobe unit and text display.
The TAR supplies the voltage necessary to run the ERM.
