Model: DX-40 / DX-60
Desc: Passive Infrared and Microwave Combination Intrusion Detector
(Standard models)
The intrusion detector shall operate on the verified intrusion principle using Passive Infrared
(PIR) and Microwave combination, and shall be Listed by Underwriter’s Laboratories, Inc..
OUTPUT AND ENCLOSURE
The detector shall provide the detection, signal processing, alarm relay, and operating
power circuitry in the same enclosure; and shall provide an alarm relay actuation upon the
detection of an intruder moving into or through its protection pattern. The enclosure shall be
ready for surface and/or corner mounting, and shall be capable of mounting to a compatible
Wall or Ceiling Mounting Bracket without modification.
The total weight shall be 5.3 oz. (150g)
The detector shall feature each single piece PIR and Microwave Unit electronics boards
whose circuitries are specifically designed for this detector alone, and which have sustained
a substantial “Burn-in” test for several days. The boards shall be mounted to a housing with
covers being secured with screws. The case shall include easy wiring knockouts and wiring
guides with wide wring space.
LED OPERATION
The detector shall incorporate Red, Yellow and Green LEDs to indicate the operating
conditions. Red LED illuminated shall indicate an alarm condition. Red LED not illuminated
shall indicate a non-alarm condition. Yellow LED illuminated shall indicate Microwave
detection. Green LED illuminated shall indicate PIR detection. Two LEDs blinking shall
indicate a trouble condition. The combination of LED colors shall show the type of troubles.
All LEDs blink in order shall indicate a warm-up period that shall be approximately 30
seconds. The LED Indicator optionally shall be capable of being disabled except warm-up
and trouble indication, using an On/Off pin switch.
POWER REQUIREMENT
The detector shall be capable of operating from a DC power source rated within the range of
9 – 18 Volts DC, and shall draw through a normal of 12 milli-Amps (mA) to a maximum of 35
milli-Amps (mA) at 12 Volts DC.
ALARM OPERATION
A condition of alarm shall occur when PIR and Microwave alarm condition are concurrently
met. The Sensitivity of PIR shall be 3.6 degree F (2.0 degree C) at 2 ft./sec. (0.6 m/sec.) at
rated distance (40ft or 60ft). The detectable speed of PIR shall be 1 – 5 ft./sec. (0.3 –
1.5m/sec.). The Microwave Detection Range Adjustment shall be carried by the Range
Selector and the Sensitivity Adjustment, between 17ft. (5m) and 40ft. (12m) (model DX-40),
or 20ft. (6m) and 60ft. (18m) (model DX-60). The Range Selector shall be “Short” or “Long”,
and the Sensitivity Adjustment shall be “L”, “M” or “H”.
The alarm period shall be approximately 2.0 seconds. The alarm output shall be capable of
handling 28 Volts DC, 0.2 Amps (A) maximum N.C.. The detector shall signal the condition
of alarm using a Normally Closed Reed Relay with terminal strip connections. The detector
shall contain a trouble output optionally through an alarm terminal. The detector shall also
contain a tamper switch that shall open when the cover is removed.
To accomplish PIR detection, the detector shall contain a sealed Pyro-Electric element that
shall have a peak in the 10-micro meters region of infrared energy for the detection. The
detector shall achieve high reliable detection performance against false and missed alarms.
The microware detection area shall be synchronized to the PIR detection area, achieving
higher detection performance and preventing errors and false alarms.
SENSOR STABILITY
The detector shall be selected either STD (Standard) or SP (Special) position according to
environmental conditions. When the detector shall be selected STD position, detection
signals shall be analyzed twice. High reliability and sharp detection shall be available in this
mode. When the detector shall be selected SP position for bad environment, detection
signals are analyzed 4 times for enhanced reliability.
Quad Zone Logic with New Spherical Lens shall create evenly distributed sensitivity
throughout the PIR detection area. Accurate focus shall create even sensitivity and high
resistance to spot temperature changes.
The Area Shaping Technology shall realize free from penetration of walls and unwanted
detection of movement outside the coverage area of the Microwave detector.
The Microwave Watchdog Circuit shall carry out a Self-checking function. When Microwave
operation fails and the Watchdog detects it, the detector shall automatically switch to single
PIR operation in Enhanced Reliability Mode avoiding Missed alarms.
To guard against false activations caused by RF interference, the detector shall incorporate
RFI Protection capability that cancels 30 Volts/meter RFI noise without any false alarm.
LENS AND DETECTION PATTERN
The detector shall contain a Fresnel lens that shall focus received infrared energy onto the
PIR sensor. The detector shall create a maximum 40 x 40 ft. (12 x 12 meters) 85 degrees
wide detection area for DX-40, and 60 x 60 ft. (18 x 18 meters) 85 degrees wide detection
area for DX-60.
The detection area of Microwave shall be set between 17ft. (5m) and 40ft. (12m) (model
DX-40), or 20ft. (6m) and 60ft. (18m) (model DX-60) by the combination of Range Selector
and Sensitivity Adjustment. Microwave Range Selector shall be set in “Short” or “Long”.
Microwave Sensitivity Adjustment shall be set in “L”, “M” or “H”.
The mounting height of the detector shall be between 5 and 8 ft. (1.5 – 2.4 meters) for
DX-40, and shall be between 6 and 8 ft. (1.8 – 2.4 meters) for DX-60.
MODEL
The Intrusion Detector shall be model DX-40 or model DX-60. (with optional Wall Mount
Bracket FA-1W) (with Compact Wall & Ceiling Mount Bracket FA-3)
