The Alpha Communications® / S.T.R.™ ECI333 QwikBUS™ Addressable Dual Input E-Call Devices are designed to be used in conjunction with the FSE1500 series QwikBUS™ intercom/emergency stations and VFSE1500 series video-intercom/emergency stations, or as stand-alone addressable devices. The ECI333 allows up to two (2) dry contact closures to trigger a call (or event) on the QwikBUS™ system, by means of the connected AlphaEntry™ (v5.5 or later) PC Master Station(s),or on the AlphaEcall™ 200 series system(s).

Typically these inputs can be a momentary or latching contact using such devices as Emergency Pull Cords, Smoke Detector (relays), Heat Detectors, Wireless Pendants, Panic Buttons, Water sensors, Motion Sensors, and many more.

The signaling type and display are fully user programmable at each associated AlphaEntry™ (v5.5 or later) Master Station location, and these calls/events can trigger other relays, devices, text messages, emails, etc.
