When planning 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.

Strobe Light
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., security systems).

Text Display
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.

Antenna
The OnAlert’s excellent radio signal is well suited to most facilities. However, in buildings having extensive metal structures or in fringe-covered areas, an external antenna with a pre-amplifier (available from WSI) helps ensure reliable signal reception.

Vibrator
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.

EAS/NOAA 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)
The 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.
