Honeywell IntelliSense IS-320 Request-to-Exit Sensor
1. Description
The IntelliSense® IS-320 is a Request-to-Exit Passive Infrared
(PIR) sensor. Mounted near an exterior door inside a building
with an access control system, the sensor provides free exit to
individuals within the building without causing an alarm.
The parts of the IS-320 are shown below.

2. Mounting Location
The IS-320 can be mounted on the wall or ceiling.

NOTE: If the maximum range of 8.4’ (2.6m) is desired, the
mounting height must be at the maximum (15’ or 4.57m).
Choose a mounting location that:
• Gives the sensor a clear line-of-sight to every part of the
detection area. Infrared energy cannot penetrate solid
objects; if the PIR cannot detect movement, the sensor
will not activate.
• Does not place the sensor directly across from one or
more windows.
• Is away from moving machinery, fluorescent lights and
heating and cooling sources.
The mounting locations available for a request-to-exit sensor
can be fairly limited. You may find that it is impossible to avoid
a source of false detection within the IS-320’s detection
pattern. In that case block the sensor’s view of that portion of
the pattern by adjusting the shutters as described in section 7.
3. Mounting Procedure
To mount the sensor, do the following:
1. Open the sensor housing by pressing on the latch with a
screwdriver. This latch is located on the end of the
sensor nearest the lens. Pull the cover up and away from
the sensor’s base.
2. Loosen rotation locking screw two (2) turns (don't
remove). Then, remove PCB assembly from the
backplate of the sensor.
3. Insert the wiring into one of the wire channels on the
sensor’s backplate.
4. Securely affix the sensor’s backplate to the wall or ceiling
using 2 #6 X 3/4 inch (3.5 X 19 mm) screws provided.
5. Reinstall the PCB assembly and adjust for short or long
range as described in section 6. Then, tighten rotation
locking screw.

4. Input/Output Description
The IS-320 inputs and outputs are as follows:
V+/V–:
Connects to AC or DC power (12 to 28 volts).
Relays:
Input/Outputs for the unit’s dual double pole/double
throw relay. The relay may be used to control a magnetic
lock or signal an access control system. All relay
connections (common, normally closed, and normally open)
for both sets of contacts are available on the terminal block.
• Relay timer settings and the reset mode setting affect
operation of this relay (see switches 3, 4, 5, and 6 in DIP
Switch Settings).
• Fail Safe/Fail Secure modes are supported (see switch 8
in DIP Switch Settings).
CAUTION: When using the IS-320 to control a magnetic
lock, we recommend that an electric suppressor such as S-4
(supplied by Northern Computers) or EL-EDS (manufactured
by EDCO) be used to provide transient protection for the
magnetic lock and relay contacts. Install the suppressor
across the leads connected to the lock as close as possible
to the lock.
Tamper:
A normally closed switch that opens when the cover
is loose or removed from the unit. Both switch contacts are
available on the terminal block.
Reader (R)*:
An optional input that can be used to activate the
unit from an isolated dry contact device. When the input is
opened, the unit reacts as if motion was detected. Timer
programming and reset modes react normally.
Door (D)*:
An optional input to monitor an isolated, normally
closed, door contact (door status monitor). The door contact
must not be connected to any other system. A DIP switch
(see switch 7 in DIP Switch Settings) determines how this
input affects unit operation.
Arm (A)*:
This optional input may be used to arm and disarm
the unit with an isolated dry contact device. These devices
might be a second detector, a card reader or keypad, or an
access control system. Opening this input allows activation
by motion while the input is open, and up to 10 seconds
after closure. Once the 10 second timer has expired, the
detector is disarmed.
Sounder (S)*:
An optional input that can be used to activate
the unit’s sounder. The sounder will be activated for as long
as the terminal is open and takes precedence over all other
sounder operation.
Ground (G)*:
The G terminals are the returns for inputs.
Devices connected to R, D, A, or S should be referenced to
the G terminals.
* The unit automatically detects connection to these terminals.
If any wiring changes are made, power must be cycled OFF
and ON for the IS-320 to detect the change.

6. Long Range/Short Range Adjustments
The IS-320 can be set to detect individuals at either a long
range (several steps from the door) or at short range
(immediately in front of the door). If the building includes a
lengthy approach to the exit doorway and no other foot traffic
in the area, choose the long-range setting.
NOTE: If the maximum range of 8.4’ (2.6m) is desired, the
mounting height must be at the maximum (15’ or 4.57m).

Choose between long- and short-range detection patterns
To set the range length:
1. Loosen the rotation locking screw.
2. Turn the PCB in its rotating base until the arrow on the
base is aligned with the appropriate notch on the base-
plate. If the sensor is ceiling mounted, choose between
the notches with the “Ceiling” label. If the sensor is wall
