ECD2 Dual Input
Wiring Harness Connector
The Alpha Communications®/S.T.R.™ ECD2 Qwik-
BUS™ Dual Input Wiring Harness Connectors are
designed to be used in conjunction with the FSE1500
series QwikBUS™ intercom/emergency stations. When
the ECD2 harness is plugged into the FSE1500 station's
PC board auxiliary connection it allows up to two (2)
dry contact closures to trigger a call (or event) on the
QwikBUS™ system, by means of the connected
AlphaEntry™ (v3.0 or later) PC Master Station(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 Sen-
sors, and many more.
The signaling type and display are fully user program-
mable at each associated AlphaEntry™ (v3.0 or later)
Master Station location, and these calls/events can
trigger other relays, devices, text messages, emails,
• Accepts one or two dry contact inputs (S1 and S2)
• Accepts momentary or latching dry contact inputs
Positive screw terminal input connectors
