DS840LSN TriTech PIR/
MW Dual Motion Detector
Features
▶ Twin-wire connection to local security network (LSN)
▶ Microwave and passive infrared (PIR) monitoring every
12 hours
▶ Pet immunity
▶ Tamper switch
▶ Temperature compensation
▶ Adjustable mirror
▶ Two installation options
The products in the DS840LSN series are wall-mounted
passive infrared (PIR) and microwave motion detectors.
When both monitoring fields are activated, passive infrared
and microwave technology triggers an alarm.
Functions
Monitoring security through microwave and PIR
technology
•
PIR and microwave: The detector carries out an internal
self test every 12 hours to check the microwave and PIR
systems. If there is a microwave or PIR system failure,
the detector carries out another test. If the second test
cannot be successfully completed on both systems, the
light-emitting diode (LED) flashes red to indicate that
the detector needs to be replaced. The detector
transmits a fault signal to the control panel via the LSN
bus.
• Factory default setting: The PIR technology ensures
detection in the event of microwave technology failure.
Configuration
Configure the detector using the software in the
corresponding LSN control panel.
PIR sensitivity settings
Select one of the following sensitivity settings using the
software in the LSN control panel:
Standard sensitivity: Minimizes false alarms and is suitable
for extreme temperatures.
Intermediate sensitivity: Suitable for instances where an
intruder only moves through a small section of the
protected area. Normal surroundings are tolerated on this
setting. Do not use this setting in areas with pets or animals.
False alarm immunity
The detector does not recognize the following animals:
• a dog up to 45 kg
•
small rodents, e.g. rats
•
up to 10 cats
• flying birds
Displays
The detector has a visible external LED, which lights up in
red, green, and yellow. Various color and flashing
combinations are used to provide status information such
as: walk test deactivated, walk test activated, power supply
turned on, dual alarm, microwave alarm, PIR alarm, and no
activity.
Signals
The detector transmits alarm, tampering, and fault
information via the LSN bus.
Temperature compensation
The PIR sensitivity is increased or lowered depending on
the ambient temperature in order to recognize human body
heat and suppress false alarms.
