Fig. 4 Dip Switch ON/OFF Positions
•
Resettable
(use when bypassing a 24-hour
contact): The relay will activate when the detector
first sees motion. Any additional motion restarts
the latch timer so that the relay deactivates only
when the detector is no longer seeing motion and
the latch time has expired.
•
Non-resettable
(use for an access control
system): The relay will activate when the detector
first sees motion and deactivate at the end of
latch time even if motion is still present.
Configuration
Use the on-board DIP Switches to configure the
operation of the detector. Refer to Figure 4 for proper
switch positioning.
Resettable/Non-resettable Timer Selection
DIP Switch 1 determines if the relay resets at the end
of latch time, or if latch time is extended by additional
motion. Refer to Table 1 and Figure 4 for more
information.
Input Power
12 or 24 VDC:
35 mA at 12 VDC when in alarm
38 mA at 24 VDC when in alarm
12 or 24 VAC:
42 mA at 12 VAC when in alarm
48 mA at 24 VAC when in alarm
Standby Power
There is no internal standby battery. Provide
38 mAh for each hour of standby time
required.
Relay
Two Form "C" contact sets rated 2.0 A at
30 VDC or VAC maximum for DC resistive
loads.
Temperature
-20°F to +120°F (-29°C to +49°C). For UL and
C-UL certified installations, the temperature
range is +32°F to +120°F (0°C to +49°C.)
Humidity
0-95% non-condensing
Dimensions
6.25″W x 1.5″H x 1.5″D

Refer to Figure 3 Relay Wiring Options.
Relay Mode
DIP Switch 2 selects the relay mode. This allows you to
select a fail safe by default, or a fail secure mode. Refer
to Table 2 and Figure 4 for more information.
•
Fail Safe:
In the event of a power loss, the REX
(Request to Exit) detector releases the device
connected to it (for example, magnetic door lock
or electric door strike.)
•
Fail Secure:
In the event of a power loss, the REX
detector does not release the device connected
to it (for example, magnetic door lock or electric
door strike).
In Fail Secure Mode, the REX detector shall be
installed in a manner that does not impair the
intended operation of panic hardware used in
conjunction with the REX detector.
Failure Secure mode must be authorized by the
local Authority Having Jurisdiction (AHJ).
LED Enable/Disable
DIP Switch 3 selects whether the on-board LED is
enabled or disabled. If enabled, the LED operates
normally when motion is detected.
When LED is enabled, it will flash on and off
when first powered up. Once the Flashing LED
stops, the REX is ready to be used.
