EF Link Supervised Transceiver Wireless Relay

Summary

The EF Link Supervised Transceiver Wireless Relay is an easy-to-install transmitter/receiver for remote alerting and status monitoring with 4 inputs and 4 relay outputs.

This unit is best suited to security alarm panels and fire alarm panels and can be configured as either a master unit or a node unit. In a single network up to 15 ‘node’ units can be connected to a ‘master’ unit.

The 4 dry contact input zones each have a corresponding relay output plus a further relay for radio link failure identification. The front panel of the unit has a number of LEDs to indicate the status of the Wireless Relay. Active relays, configuration status (i.e. master or node), radio signal jams/fails and the signal strength of incoming transmissions are all indicated.

With minimal effort users can quickly create a UHF linked wireless radio network using the plug-and-play capabilities of the EF Link Supervised Transceiver Wireless Relay. User configurable settings are selectable via switches within the unit itself meaning there’s no need for a PC interface. Settings that can be adjusted in this way are:

• normally open/closed default conditon for each input zone
• relays set as either latching, change of state or self-reset

EF-Link Wireless Networking Protocol is a designed for a low-data rate over short distance communication. This device also employs acknowledge-back and LBT (list before talk) techniques for rubustness and reliability.
