Honeywell VARIODYN D1 Alarm Transponder - ESSER Series

The Honeywell VARIODYN D1 Alarm Transponder is an optical signaling device for PA and voice alarm systems, manufactured under the ESSER brand. Designed to drive visual alarm recipients via two supervised relay outputs per unit, it operates independently within the VARIODYN D1 cabinet. Procure.ae supplies this audio equipment component across the UAE and wider Middle East & Africa region.

This device provides optical alarm signaling by connecting up to ten visual devices on each of its two supervised relay lines. It operates independently, driven directly by the VARIODYN D1 system, while reporting any relay line failures back for monitoring. The unit draws power from the system's 24 V DC supply and can be mounted via DIN rail in an enclosure or stand within the cabinet.

Each VARIODYN D1 transponder connects to attachment points such as DOM, UIM, or VARIODYN D1 Comprio interfaces. A maximum of four transponders can be installed per connection point to ensure reliable signal distribution. Procure.ae offers bulk quotations and project support for this ESSER series audio equipment installation.
