Ziton A50E-2 Installation Sheet

A50E-2 Line Relay Unit Installation Sheet
Description
The A50E-2 Line Relay Unit is an addressable device used to
provide one Form C change over dry relay contact to control
external appliances (door closers, fans, dampers, etc.) or
equipment shutdown. The system firmware ensures that the
relay is in the proper ON/OFF state. Upon command from the
control panel, the relay energizes. TB2-6 and TB2-7 provide a
normally-closed relay connection; TB2-7 and TB2-8 provide a
normally-open relay connection. One device address is
required.
Up to 127 devices can be assigned to the loop. All devices
incorporate a binary DIP switch enabling them to be given a
unique address. A red LED indicator illuminates when the unit
has activated.
