Description
The SE coordinator is a device controller for up to 15 SE receivers. Its primary function is to
monitor the SE receivers and report conditions and events to the Central Console via Ethernet
communication. It also provides power output to certain devices.
Installation
The SE coordinator can be mounted in one of two different sized enclosures. It is always
mounted indoors. The devices are connected to the SE coordinator by means of a multi-drop
RS-485 twisted pair wire. Each bus is capable of supporting up to 15 SE receivers (excluding
the SE coordinator). A Security Escort system supports up to 1024 SE coordinators.
Configuration
Each SE receiver is identified to the SE coordinator by an address which is set during system
installation using the dip switch on the SE receiver circuit board. SE coordinators
communicate on the data bus with individual devices by issuing commands, which contain the
SE receiver's address.
Setup and testing
Each SE coordinator and the devices connected to it are set up and can be tested remotely
from the Central Console. Also, each SE coordinator reports any problems, such as low
battery, immediately upon detecting them.
Function during an alarm
When a SE receiver detects an alarm, it goes into an "Off Normal" state. To quickly locate any
devices which might be in the "Off Normal" state, the SE coordinator issues global commands
(which are interpreted simultaneously by all of its devices) approximately 10 times per
