Using an Echoflex Magnetic Contact Sensor with an Occupancy/Vacancy Sensor
Question
What is the expected behavior of a space with an Echoflex Magnetic Contact Sensor (MC-31) in conjunction with an Occupancy/Vacancy Sensor?
Explanation
Echoflex controller are programmed for hospitality applications of the MC-31 and occupancy sensor allow them to work together with an Echoflex controller that both units are linked to. When the controller is used in a hotel or dormitory setting, it is typically linked to a keycard switch station or to both an entry door sensor and an occupancy sensor.
Answer
Occupancy is determined by a combination of the door sensor and the ceiling sensor. Each time the door is opened and closed and the sensor detects motion, the room locks into an occupied state. If the sensor sends a vacancy message without the door opening and closing, the lights will still remain on, as controller knows the room is still occupied. If the door opens and closes, but no motion is detected before the occupancy auto-OFF timer expires, the room will co into a vacant state and lights will turn off. If an occupancy message is sent when the room is in a vacant state, the room will lock into an occupied state until the entry door opens and releases the lock.
