Operation
TR 100-M & TR 150-M
Manual ON /
Automatic Off
Power Packs
The occupants must
operate a low voltage
momentary switch to
turn lights ON. When
the occupancy sensor
is the only input keeping
the load ON, the load
turns OFF after the
sensor’s time delay
elapses. If the sensor
detects occupancy
and re-triggers within
30 seconds after the load
turns OFF, the load will
turn ON again.
Isolated relay
The TR 150-M and
TR 150-A contain a
single-pole, double-
throw isolated relay with
normally open (yellow
with red stripe), normally
closed (yellow with black
stripe), and common
(yellow) outputs rated 1
Amp @ 30 VAC/VDC. The
isolated relay is used with
HVAC controls and other
low voltage devices.

Operation
LED Indicator
The power pack led
indicator follows the state
of the relay under normal
operating conditions.
When the LED is off the
relay is open and the load
is off. When the LED is
illuminated the relay is
closed and the load is on.
If the 24 VDC is in
overload (greater than
250mA) the LED indicator
will slowly flash, the load
will turn off but 24 VDC
will continue to be
available.
If there is a short in the
24 VDC wiring the LED
will turn off, the load
will be turned off and
the 24 VDC will be shut
down. After the short is
removed the 24 VDC will
return after 3 seconds.
If there is an over
temperature in the power
pack (100°C) the LED
will flash rapidly, the load
will be turned off but
24 VDC will continue to
be available. The power
pack returns to normal
operation when the
temperature falls below
65°C.
