The PoE 8138 IP Color Visual Alerter is a four-color LED visual alerting IP endpoint in amber, blue, green and red. This outdoor-rated PoE IP strobe light is designed for telephone ringing where noise, noise sensitivity, or hearing impairment are at issue. Together with Algo IP speakers, the 8138 is also commonly deployed as part of public address (PA) and mass notification systems to visually alert for safety, security, and emergency events.
