Operation
The SEC 4855 Relay Module is used with SEC Supervision Plus software to provide relay contacts at local or remote
locations. Each SEC 4855 Relay Module is assigned a unique identification number, allowing multiple modules to be
connected anywhere on the SEC network. SEC Supervision Plus continuously polls and updates the SEC 4855 Relay
Modules.
Each SEC 4855 Relay Module consists of one Control Board and either 1 or 2 Relay Boards depending on model selected.
The Control Board has 2 LED’s, one for Power and the other for Data Transmission. The Control Board communicates with
the SEC Supervision Plus software, activating the relays when the alarm conditions are present. The Relay Board consists
of 8 relays, 8 LED’s and the terminals for the field wiring connections.
The individual relay coils can be programmed (using SEC Supervision Plus) for normally energized or normally de-energized operation. The relays can be manually controlled or deactivated by SEC Supervision Plus. Programmable time delay
and latching/non-latching features are also standard with the SEC 4855 Relay Module.
The Control Board and the Relay Boards are connected together in an anodized aluminum bracket. The units are
suitable for mounting directly to an electrical enclosure panel, or can be purchased already mounted in various types of
enclosures.
