The DT CM COM2-24 Dual Technology Presence
Detector utilizes passive infrared and ultrasonic technologies
to detect the presence or signature of a person in a space.
The logic options for initial “ON” and “Maintained” state of
occupancy gives design engineers and installation
contractors the choice for proper control of lighting and
HVAC in difficult applications where detection options are
needed in a single device. Lighting loads are controlled in
relation to both presence detection and selectable ambient
light levels with the integrated force off photocell to
maximize energy savings. The separate HVAC dry contact
output is signaled only by presence detection and has a
separate “ON/OFF” delay time feature set. STEINEL’s world
class PIR optics and ultrasonic signal processing provides
unparalleled line of sight and volumetric presence detection.
Operational choices of auto on or manual on with a
momentary or maintained switch input. The convenient
“COM-Link” feature enables multiple sensors to link together
via the communication link for peer to peer grouping
achieving expanded detection zones with control set up
functions set at only one primary sensor for the entire group.
The available service and user wireless remotes provide
simplified commissioning and occupant convenience.
