Doc: Architect / Engineer Specifications
Model: AX-70TN / AX-130TN / AX-200TN
Desc: Outdoor Photoelectric Intrusion Detector (standard models)
The intrusion detector shall operate on the verified intrusion principle using Infrared
Photoelectric (AIR), 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 housing cover and
chassis shall be highly durable and heat resistant, and shall be capable of mounting to a
Wall or Pole mounting either outdoor or indoor without modification. The enclosure shall be
weatherproof construction rated to IP65 (International Protection Code 65).
The total weight (both Transmitter and Receiver) shall be 22.9 oz. (650g)
The detector shall feature a single piece electronics logic board whose circuitry is
specifically designed for this detector alone, and which has sustained a substantial “Burn-in”
test for several days. The case shall include easy wiring knockouts, and 4 pieces of Pole
-mounting Bracket.
LED OPERATION
The detector shall incorporate dual Green and Red LEDs to indicate the operating
conditions on the Transmitter and Receiver, respectively. On the Transmitter, a Green LED
illuminated shall indicate a transmitting condition, and Green LED not illuminated shall
indicate a non-transmitting condition. On the Receiver, Red LED illuminated shall indicate
an alarm condition, and Red LED not illuminated shall indicate a non-alarm condition.
POWER REQUIREMENT
The detector shall be capable of operating from a DC power source rated within the range of
10.5 – 28 Volts DC. The current draw (Transmitter + Receiver) shall be a maximum 38
milli-Amps (mA) for model AX-70TN, a maximum of 41 milli-Amps (mA) for model AX-130TN
1
and a maximum of 45 milli-Amps (mA) for model AX-200TN.
ALARM OPERATION
A condition of alarm shall occur when the alarm condition are met. The Beam Interruption
Period shall be selectable from 50, 100, 250 or 500 milli-seconds (ms) to increase stability
while maintaining reliability at every installation site. The alarm period shall be 2.0 +/- 1
seconds nominal. The alarm output shall be capable of handling 28 Volts DC, 0.2 Amps (A)
maximum N.C. output. The detector shall signal the condition of Alarm using a Normally
Closed Reed Relay with terminal strip connections. The detector shall also contain a tamper
switch (N.C.) with a capable of handling 28 Volts DC, 0.2 Amps (A) maximum, that shall
open when the cover is removed.
SENSOR STABILITY
The detector shall remain stable even in high temperature conditions. The detector shall be
rated to operate within a temperature range of –31 degree F to +140 degree F (-35 degree C
to +60 degree C), it shall be used with the optional heating unit model HU-3 under the
environment of –13 degree F (-25 degree C) or less minus. The detector shall also tolerate a
humidity rate of 95% maximum. No false alarm shall occur within these operating condition.
The detector shall contain an A.G.C. (Automatic Gain Control) Circuit to continually monitor
for gradual changes in the signal’s strength caused by changing weather conditions. It shall
adjust the sensitivity accordingly to maintain the proper signal level for the current
environmental conditions.
The detector shall provide protection against rain, dust, and insects by means of a sealed
enclosure housing. The OPTEX casing design shall also reduce condensation and water
build-up.
The detector shall feature frost and dew protection. An anti-frost and convex visor design
shall be incorporated to protect the detector from the effect of frost or snow. This convex
design shall allow beam passage even when the cover is completely frosted over. The
ultra-high power Transmitter shall maintain stable operation with as much as 99% of the
beam’s energy blocked by extreme weather conditions such as snow, fog, heavy rain dust
storms, or icy build-up.
2
The detector shall utilize Twin Synchronized Pulsed Beams with size analysis technology to
eliminate false alarms due to birds or flying objects. The “And Gate” dual beams shall be
sharply defined and shall obtain their optimal signal strength easily. They shall require
simultaneous interruption of both beams to trigger an activation ; no activation shall be
generated when birds, insects, or falling leaves break just on beam.
An improved Electro-Magnetic surge absorber and high surge resistive relay shall be
installed to protect from lightning surges and maintain stable operation. The detector shall
remain stable against over 14 kilo Volts (kV) of lightning surge.
LENS AND DETECTION PATTERN
The high-grade spherical lens shall create more sharply defined and precise infrared beams
to ordinary Fresnel lenses. The precise area of the detection field shall be specific to each
model. Model AX-70TN shall feature a detection range of 70ft. (20 meters), with a Maximum
Arrival Distance of 700ft. (200 meters). Model AX-130TN shall feature a detection range of
130ft. (40 meters), with a Maximum Arrival Distance of 1,300ft. (400 meters). Model
AX-200TN shall feature a detection range of 200ft. (60 meters), with a Maximum Arrival
Distance of 2,000ft. (600 meters).
Easy optical beam alignment shall also be incorporated into the detector. The View finder
shall provide rough alignment, while voltage meter jacks shall allow fine tuning. The
alignment angle may be adjusted easily either horizontally (180 degrees = +/- 90 degrees)
or vertically (10 degrees = +/- 5 degrees).
MODEL
The Intrusion Detector shall be model AX-70TN, model AX-130TN or model AX-200TN.
(with optional Heating unit HU-3, requires 24 Volt AC/DC 420 milli-Amps. (mA) maximum),
(with optional Back cover BC-3), (with optional Pole side cover PSC-3)
