Introduction
Actuators and sensors for monitoring, alerting, controlling and adjusting can be connected to the
STRB (control relay board) in OfficeCom/OfficePoint. Actuators are relays that can be controlled
from each station by means of a code (e.g. a door opener). Sensors can detect changes in the state of
the connected unit and select a call number stored in the system (e.g. thermostats, motion detectors,
etc.).
The board has a total of 4 outputs (each in the form of 2 floating switch contacts) and 4 control inputs
