The SREX-100 is an active infrared request to exit sensor for interior applications located
within the protected premise. It is U.L. listed as a request to exit device under the U.L.
UL294 and the CAN/ULC-S319 standard. The SREX-100 is rated a “class 1” as per the CAN/
ULC-S319 standard. The SREX-100 is designed to mount over the door header so that its de-
tection pattern is placed directly over the door handle. When the user reaches for the door
handle the exit device releases allowing the person to exit. The active detection curtain is well
defined to keep the door secure while rejecting parallel traffic and objects placed under it.
IF TECHNICAL ASSISTANCE IS REQUIRED CALL 1 800 645-5538
NOTE:
FOR U.L. LISTED INSTALLATIONS THE SREX-100 SHOULD ONLY BE POWERED BY A U.L. 294
LISTED POWER SUPPLY, AS WELL AS CONNECTED TO A U.L. LISTED ELECTRICAL LOCKING
(EL) DEVICE. FOR CAN/ULC-S319 LISTED INSTALLATIONS THE SREX-100 SHOULD ONLY BE
POWERED BY A ULC--S319 LISTED POWER SUPPLY AS WELL AS CONNECTED TO A ULC-
S319 LISTED ELECTRICAL LOCKING (EL) DEVICE, CARD READER/KEYPAD AND DOOR/REX
SWITCHES.
THE USE OF ANY ADD-ON, EXPANSION, MEMORY OR OTHER MODULE MANUFACTURED OR
SUPPLIED BY THE MANUFACTURER’S REPRESENTATIVE WILL INVALIDATE THE CAN/ULC-
S319 CERTIFICATION.
WHEN USED WITH ELECTRIC STRIKES ON SUPERVISED PORTALS, REQUEST-TO-EXIT DE-
VICES SHALL BY-PASS PORTAL ALERTS CAUSED BY EXITING. WHEN USED WITH ELEC-
TROMAGNETIC LOCKS ON SUPERVISED PORTALS, REQUEST-TO-EXIT DEVICES SHALL
SIGNAL THE ACCESS CONTROL UNIT TO RELEASE THE ELECTROMAGNETIC LOCKS AS
WELL AS TO BYPASS PORTAL ALERTS CAUSED BY EXITING.
TERMINAL AND LEADS COMPLY WITH CSA, C22.1, CANADIAN ELECTRICAL CODE, PART I,
SAFETY STANDARD FOR ELECTRICAL INSTALLATIONS.
FOR U.L. 294 AND NFPA 101 SECTIONS 7.2.6.2.1 WIRE THE LOCKING DEVICE FOR FAIL-SAFE
OPERATION.
CAN/ULC-S319 LIMITS THE RATED OUTPUT OF THE AUDIBLE SIGNAL DEVICE, (STATED AS A
SOUND PRESSURE LEVEL), (SPL), FROM 70 dBA TO A MAXIMUM OF 100 dBA AT 1 METER.
UL-294 LIMITS THE RATED OUTPUT OF THE AUDIBLE SIGNAL TO A MINIMUM OF 85 dBA AT
10 FEET.
THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO
THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTER-
FERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED THAT MAY
CAUSE UNDESIRED OPERATION.

NOTE: The SREX-100 contains a double pole-double throw relay and the two sets of
relay contacts are referred to as A and B.
The Card Reader/Keypad and the Door Position Switch are dry inputs.
The SREX-100 is factory pre-set at the five degree angle. If there is an obstruction in the
sensor field preventing a clear view of the door handle it will be necessary to change the
viewing angle. Un-plug the connector and slide the PCB from the housing with the clips
attached. Do not remove the clips from the PCB! Change the viewing angle to the zero
degree angle. It is recommended that the sensor be powered and both hand and walk
tested. If the sensor is detecting erratically, the IR beams may be reflecting off the door
handle and the viewing angle should be adjusted outward. Slide the PCB back into the
housing and leave the right end cap off until all final adjustments have been made.

ADJUSTMENT OF SENSOR FIELD

After the SREX-100 has been wired and powered the sensor can now be adjusted to the
installation requirements.
DETECTION RANGE
The detection distance is adjusted by the RNG, (range), potentiometer located at the
upper left hand side of the PCB. The range is 20 to 48 inches.
Turning the potentiometer clockwise increases the range, turning the potentiometer coun-
terclockwise decreases the range.
RELAY ON TIME
The relay on time is adjusted by the TIME potentiometer which is the center potentiome-
ter located at the upper left hand side of the PCB. The relay on time range is 1/2 to 60
seconds. The Time potentiometer is non-linear with the first 10 seconds covered by the
first half of the potentiometer and 11 to 60 seconds covered by the second half of the
potentiometer. Turning the potentiometer clockwise increases the relay on time, turning
the poteniometer counterclockwise decreases the relay on time.
BUZZER VOLUME
The buzzer volume is controlled by the VOL potentiometer located at the upper right
hand side of the PCB. Turning the potentiometer clockwise increases the buzzer vol-
ume, turning the potentiometer counterclockwise decreases the buzzer volume.

DIP SWITCH SETTINGS
SWITCH 1 ON FAIL-SAFE MODE
SWITCH 1 OFF FAIL-SECURE MODE
When the SREX-100 is in constant dectection, more than 10 seconds, It will go into a
fail-safe or fail-secure mode depending upon the switch setting.
SWITCH 2 ON RELOCK MODE, DOOR POSITION
When a normally-closed door contact is installed the door will relock after the door is
opened and then closed.
SWITCH 2 OFF TIMER MODE
The door will relock after the preset relay on time.
SWITCH 3 ON DOOR POSITION RELOCK TIME IS A FIXED 10 SECONDS
SWITCH 3 OFF DOOR POSITION RELOCK TIME IS A FIXED 30 SECONDS
SWITCH 4 ON DOOR UNLOCK TIMER
If switch 2 is in the off position,(timer mode), then door will remain unlocked as long as
there is activity in the detection range. If there is no activity then the timer will restart and
relock the door after the preset time.

NOTE: The SREX-100 and devices connected to it must be mounted inside
the protected area to be UL-294 and ULC-S319 compliant.
STEP 1. Remove the Phillips head screw holding the right end cap. Take off
the right end cap only.
STEP 2. Slide the lens out of the housing.
STEP 3. Slide the PCB with clips attached from the housing.
Do not remove clips.
STEP 4. Position the SREX-100 drill template on door frame or above door
frame over door handle.
STEP 5. A 5/16” diameter hole is required in door frame or mounting surface
to allow cable entry. This hole is located at the right side of the
housing thru the elongated hole.
STEP 6. Fasten the SREX-100 housing with the two TEC screws provided.
It may be necessary to drill a 1/8” pilot hole for ease of screw installa-
tion.
CAUTION: ESD electrostatic discharge: The circuit board is vunerable to
damage by electrostatic discharge. Before handling PCB dissipate
your body’s charge.
