Specifications
• Input Power:
Connects directly to the Multiplex Bus of the
Control Panel and optionally to an auxiliary
12 VDC source.
• Current Draw:
2-Wire:
LED Off:
< 350 µA draw on Mux Bus.
In Alarm; LED On: 2 mA draw on Mux Bus.
4-Wire:
LED Off:
< 350 µA draw on Mux Bus.;
0 mA draw on Aux. power.
In Alarm; LED On: < 350 µA draw on Mux Bus;
3 mA draw on Aux. power.
• Standby Power: There is no internal standby battery. Connect
to DC power sources capable of supplying
standby power if primary power fails. For each
hour of standby time needed, 350 µAh are
required. For UL Listed Requirements, four
hours (1400 µAh) minimum are required.
• Coverage:
360° by 60 ft. (18.3 m) diameter coverage
when mounted on 8 to 18 ft. (2.4 to 5.5 m)
high ceilings. Pattern consists of 64 zones
grouped into 16 barriers, with one additional
zone looking straight down from the unit
(sabotage). Each barrier is 30 ft. (9.2 m) long
and 4.4 ft. (1.3 m) wide at 30 ft. (9.2 m).
Choice of two optical modules depending
on ceiling height. For UL Listed
Requirements, the coverage is 360° by 54 ft.
(16.5 m) when mounted 10 to 13 ft. (3.1 m to
4.0 m) using the AR8-13 array and when
mounted from 15 to 18 ft. (4.6 m to 5.5 m)
using the AR13-18 array.
• Sensitivity:
Selectable for Standard, Intermediate or High.
• Tamper:
A tamper condition is signaled through the
Multiplex Bus and displays at the system
keypads.
• Temperature:
The storage and operating temperature
range is -20°F to +120°F (-29°C to +49°C).
For UL Listed Requirements, the
temperature range is +32°F to +120°F (0°C
to 49°C).
• Control Panel
Requirements:
DS7400, DS7400X, or DS7400Xi Control
Panel with a DS7430 or DS7436 Multiplex
Expansion Module. DS7400 and DS7400X
require ROM version 1.07 or greater. The
9000 Series Control/Communicators with
D8125MUX Module installed.
• Patents:
This device is covered under one or more of
the following U.S. patents: #4,764,755,

Tamper
The mounting surface should be solid and vibration free
(i.e., drop tiles should be secured if the area above the
tiles is used as an air return for HVAC systems).
IMPORTANT
• Select a location that is most likely to intercept an intruder moving
across the coverage pattern. The recommended mounting height
range is 8 to 18 ft. (2.4 to 5.5 m).
• Remove the cover by turning counterclockwise.
• Remove the base from the enclosure by pressing the two
enclosure release tabs inward while lifting the enclosure away
from the base.
Hint:
Slightly rock the enclosure side-to-side during removal,
to overcome the friction caused by base-to-enclosure
terminal pins.
• Route wiring as necessary to the rear of the base and through
the center hole.
Be sure all wiring is unpowered (de-energized) before
routing.
• Securely attach the base. Depending on local regulations, the
base may be directly surface mounted using anchors, mollies
or wing-nuts, or may be mounted to standard four-inch octagonal
and square electrical boxes.
NOTE:
The MX938i base will not completely cover a four-inch
square box. Where aesthetics are important, a four-inch
octagonal box is recommended.
Hint:
Mounting to removable ceiling tiles is not recommended
unless a sandwich is made of the base, ceiling tile and a
back plate behind the tile. Covers used for four-inch
octagonal and square boxes make a suitable back plate
(when used with bolts and wing nuts, as an example).
• Replace the enclosure on the base.
• Select an Optical Module (AR8-13 or AR13-18).
- For ceilings between 8 and 13 ft. (2.4 m and 4.0 m) from the
floor, use the optical module marked AR8-13. This marking
can be found next to the two optical module tabs. For ceilings
between 13 and 18 ft. (4.0 m and 5.5 m) high, use the optical
module marked AR13-18.
- To replace an optical module, push the optical module tabs
toward the center until the module snaps free of the circuit
board. Holding the new module by the tabs, snap the new
module into place.
Avoid fingerprints on the mirrored surfaces. If the mirrored
surfaces become soiled or otherwise marked, they can
be cleaned using a soft, clean cloth and any commonly
available mild window cleaner.

normal environments on this setting. This setting
will improve your intruder catch performance.
• High Sensitivity: Fast response to intruder signals. High
For use in quiet environments where thermal and

Signal Gain
NOTE:
The MX938i permits selection of the signal gain
depending upon the environment to be protected. The
gain select jumper is located under the optical module.
• High Gain: Recommended for large coverage High Gain
HI
applications up to 60 ft. (18.3 m) in diameter. The
MX938i is shipped in this setting. If the gain jumper is LO
missing, it will default to high gain.
• Low Gain: Recommended for applications where the Low Gain
HI
area to be covered is 40 ft. (12.2 m) or less in diameter
and for applications where the High Gain setting may LO
be too sensitive for environmental extremes.
NOTE: Setting the MX938i for the LOW Signal Gain setting reduces
the Coverage area to 40 ft. (12.2 m) in diameter.

Address Switch Settings
• Set the address switch settings (see page 3) before connecting
the MX938i to the multiplex bus.
IMPORTANT
No two devices may be set to the same address. Having
two or more units set to the same address may prevent
fault detection or cause multiplex bus failure.
Configuration Jumpers
Configure the detector using the appropriate Configuration Jumper
settings (refer to the following diagram for jumper locations).

Setup and Walk Testing
8.0
Before walk testing, the system should be fully wired,
powered, and programmed.
IMPORTANT
• Configure LED Configuration Switch (S1) to LED ON.
•
Replace the front cover.
NOTE:
•
•
•
•
All testing must be performed with the
front cover in place.
Wait at least 2 minutes (with no motion in the
coverage area) for the detector to setup.
Walk test across the coverage pattern.
The edge of the coverage is determined by
activation of the LED.
Walk test the unit from both directions to determine the
boundaries.
Maintenance
• The range and coverage should be checked in accordance with
the Walk Testing section (6.0) on a regular basis.
• Consult the Control Panel’s User's Guide for the procedure on
performing a zone test. Performing a zone test on a regular
basis assures an alarm output prior to arming the system.
• Excessive handling of the mirror surfaces may lead to
performance degradation.
9.0
Coverage Patterns
• Refer to the mirror module and pattern drawings for masking
information.
• Before masking, be sure the chosen mirror surface is the correct
one. When removing masking, remember, many adhesives will
either destroy the mirror’s surface or leave residue behind to
reduce coverage performance.
On 2-wire systems, configure the LED to OFF when
finished with walk tests.
