Passive Infrared Occupancy Sensing
Passive infrared (PIR) technology employs a highly sensitive, specialized lens that divides the
field-of-view into sensor zones. The sensor detects motion when a person passes between zones,
achieving dependable motion detection with superior immunity to false triggering from
vibrations, inanimate objects, or movement in an adjacent corridor. The detection sensitivity is
adjustable for optimum performance. Timeout can be set anywhere from 30 seconds to 30
minutes to maintain occupied status during short periods of inactivity. A half mask and
perforated mask are included to customize the coverage area.
Vacancy Only Mode with Grace Occupancy
The GLS-OIR-CSM-EX-BATT can be configured via the control system program to sense vacancy
only. In this mode, lighting and other equipment is shut off automatically when a room becomes
vacant, but can only be turned on manually. If the lights turn off while someone is in the room,
they can be turned back on by simply waving a hand within the 15 second grace period.
infiNET EX® Wireless Technology
Ultra-reliable infiNET EX wireless technology provides steadfast two-way RF communications
throughout a residential or commercial structure without the need for physical control wiring.
The GLS-OIR-CSM-EX-BATT communicates with a Crestron control system via an infiNET EX
wireless gateway (CEN-GWEXER, sold separately), and functions as part of a complete network
of wireless sensors, lighting dimmers, motorized shades, thermostats, door locks, keypads,
handheld remotes, and other devices.
Crestron infiNET EX wireless technology employs a mesh network topology so each “EX” device
on the network acts as a routing node or “expander,” which relays the signals it receives on to
other EX devices within range. This effectively extends the total range of the network and
provides multiple redundant signal paths for extra reliability. A maximum of six “hops” across
routing nodes is allowed, although a maximum of three is recommended. Please note that the
GLS-OIR-CSM-EX-BATT and other battery-powered infiNET EX devices only operate as leaf
nodes and do not provide expander functionality. If needed, up to five dedicated infiNET EX
expanders (CLW-EXPEX, sold separately), may be deployed as supplemental routing nodes to fill
