Installation Instructions
for the MX775
Multiplex PIR Intrusion Detector
1.0 Specifications
• Input Power: Connect to the Multiplex Bus of the control panel.
• Current Draw: Less than 200 micro-amps. Two milli-amps when in walk test mode
(LED on).
• Standby Power: There is no internal standby battery. Connect to DC power sources
capable of supplying standby power if primary power fails. Two hundred micro-amp-
hours required for each hour of standby time needed. Eight hundred micro-amp-hours
minimum are required for U.L. Listed Requirements.
• Coverage: Broad (standard) 50 ft. by 50 ft. (15 m by 15 m)
Barrier* 80 ft. by 16 ft. (24.4 m by 4.8 m)
Long Range* 120 ft. by 10 ft. (36.6 m by 3.1 m)
*Barrier and Long Range mirrors are available as options.
• Sensitivity: Standard, Intermediate or High.
• Tamper: A Tamper condition is signaled through the Multiplex Bus and displayed at the
keypads.
• Temperature: The storage and operating range is -20° to +120°F (-29° to +49°C). For
U. L. Listed Requirements, the temperature range is +32° to +120°F (0° to +49°C).
• Requirements: A DS7400, DS7400X, or DS7400Xi control panel with a DS7430 mul-
tiplex expansion module. The DS7400 and DS7400X require ROM version 1.07 or greater.
• Options: B328 Gimbal Mount Bracket, B333 Swivel Mount Bracket, TC6000 Test Cord.
NOTE: Misalignment of the detector when using an optional mounting bracket may
reduce range.
• U.S. Patent Number: #4,764,755.
2.0 Multiplex Programming
Before installing the MX775, its address and other information must be programmed into
the control panel.
• Program the control panel using the DS7400, DS7400X or DS7400Xi Reference Guide.
Refer to the Zone Programming section in the control panel manual.
• Define the MX775’s address (zone number), its type (multiple zone input device), its
partition (1-4), and which zone function it will follow (1-15).
For example: Program zone 9 to be a single input (the MX775) in partition
1 that follows zone function 1.
Procedure:
• Enter the Programmer’s Mode.
• Enter address 0030 (DS7400 or DS7400X) or address 0026 (DS7400Xi).
• Enter the data digits as [0] and [1] followed by the [#] button.
• Exit the Programmer’s Mode.
• If you wish to use the BusLoc® feature you must program a 5 digit code (e.g. 5 4 3 2 1)
at programming address 9999. BusLoc® is a proprietary method of tying the multiplex
zones to the control panel to prevent the system from being taken over. Using BusLoc®
will program an invisible identification code into the multiplex zones. If you are not using
the BusLoc® feature skip the next procedure.
For example: Program the BusLoc® code to be 54321.
Procedure:
• Enter the Programmer’s Mode.
• Enter address 9999.
• Enter the 5 digit code followed by the [#/Command] button (do not lose this code).
• Exit the Programmer’s Mode.
• Once the pre-programming is done, you are ready to program the MX775.
• Disconnect all multiplex devices from the DS7430.
• Program the MX775 through the control panel.
- Enter the Programmer’s Mode.
- Enter the multiplex programming mode by entering [9] [9] [9] [5] followed by the [#]
button.
- The control will then take a few seconds to check the multiplex connection to confirm
nothing is connected to it.
The display will show the following:

- The display will then call-up the first zone you have pre-programmed to be a multi-
plex zone. To access a different zone, press the [*] key, then enter the three digit
address of the zone you want. The display will show the following:
• Before doing anything else, reconnect the MX775 (that coincides with the displayed
zone) to the multiplex bus of the DS7430. Press the [#/Command] button to continue
programming. The display will ask whether you are programming a sensor or a contact.
It will show the following:
• Press the [4] button to program the MX775 to the control panel.
• If the MX775 is successfully programmed, the keypad will increment to the next zone (if
there is one) pre-programmed as a multiplex zone. If the zone is unsuccessfully pro-
grammed, the keypad will sound a three-beep error tone.
Hint: Mark the zone numbers on each unit to assist with device location.
Disconnect the device you just programmed and connect the next de-
vice (that belongs to the displayed zone) to the multiplex bus of the
DS7430 and press the [#] button. Continue programming.
Any devices that are programmed as 24-hour zones will cause an
alarm when you exit the Programmer's Mode. Reports for these
zones will be sent if they are programmed.
• If no other zones have been pre-programmed, the display will show the following:
• If you wish to exit the Zone Programmer’s Mode, press the [*] button for 2 seconds. This
brings you back to the Programmer’s Mode. To exit the Programmer’s Mode, press the
[*] button for 2 seconds.
3.0 Mounting
Note: The mounting surface should be solid and vibration free.
• Select a location that is most likely to intercept an intruder moving across the coverage
pattern. The recommended mounting height range is 6.5 ft. to 8.5 ft. (2 m to 2.6 m).
• Remove the cover. Insert a thin flathead screwdriver into the notch at the bottom of the
cover and pry up.
• Remove the circuit board/mirror unit from the enclosure. Push the board/mirror unit
toward the top of the enclosure until it clears its four retainer tabs, then lift it out.
• Open the knock-out wire entrance and route the wiring through.
