MX775i Multiplex PIR
Intrusion Detector
Features
▶ Interchangeable, pointable mirrors
▶ Selectable sensitivity
▶ Built-in tamper switch
The MX775i is a PIR intrusion detector that provides a
variety of coverage patterns through the use of
interchangeable mirrors and the choice of mirror angle
settings. It is designed to be surface or corner mounted, but
can be mounted with any of three optional brackets. This
provides further flexibility in aiming the detector. It is
designed to connect to the Multiplex Bus of a control panel
and optionally to an auxiliary 12 VDC power source. It is
compatible with the DS7400Xi Series Control Panels with a
DS7430 or DS7436 Multiplex Expansion Module or with
GV2 and G Series Control Panels with a D8125MUX Module
installed.
Note The DS7400 and DS7400Xi require ROM
version 1.07 or greater.
Functions
Interchangeable, Pointable Mirrors
The detector comes with a standard broad pattern mirror
and two optional mirrors are available: a long-range pattern
mirror and a barrier pattern mirror. To change the mirror,
pull it out from its resting grooves. To adjust the mirror
vertically (from +1° to -18°) slide the mirror forward or back.
To adjust the mirror horizontally (±10°) rock the mirror from
side to side.
Three Sensitivity Settings
Selectable for Standard, Intermediate or High:
•
Standard: Recommended setting for maximum false
alarm immunity. Tolerates environment extremes on
this setting. Not recommended for Long Range or
Barrier type patterns. The detector is shipped in
Standard Sensitivity mode.
•
Intermediate: Recommended setting for any location
where an intruder is expected to cover only a small
portion of the protected area. Tolerates normal
environments on this setting. This setting will improve
your intruder catch performance.
• High: Fast response to intruder signals. For use in quiet
environments where thermal and illumination
transients are not anticipated.
Internal Tamper Switch
The internal tamper switch sends a signal to the control
panel's Multiplex Bus for display at the keypads when the
detector's cover is removed.

Installation/Configuration Notes
Wiring
Do not use shielded cable. Use wire that is no smaller than
0.8 mm (22 AWG) to connect the detector to the control
panel.
Coverage
The recommended mounting height range is 2 m to 2.6 m
(6.5 ft to 8.5 ft). Misalignment of the detector when using
an optional mounting bracket may reduce range.
The range is variable depending on the vertical angle setting
of the mirror. The chart indicates vertical angle settings for the
desired mounting height, mirror type, and range.
