Doc: Architect / Engineer Specifications
Model: AX-350TF / AX-650TF
Desc: Outdoor Photoelectric Intrusion Detector (4 selectable beam frequencies)
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 IP54 (International Protection Code 54).
The total weight (both Transmitter and Receiver) shall be 97.0 oz. (2,750g)
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 Red LEDs to indicate the operating conditions on the
Transmitter and Receiver. On the Transmitter, a Red LED illuminated shall indicate a
transmitting condition, and the same LED not illuminated shall indicate a non-transmitting
condition. On the Receiver, an “Alarm Condition” Red LED illuminated shall indicate an
alarm condition, and the same LED not illuminated shall indicate a non-alarm condition.
“The Alignment Level Indicator” 5 Red LEDs on the Receiver shall indicate a rough condition
for a beam alignment. Their illumination shall represent the level of alignment ranging from
“Poor” to “Excel”. Each LED shall indicate 3 steps of alignment, slow flicker is okay, fast
flicker is better, continuously ON is the best, totally providing 15 graduated stages.
Another red LED illuminated on the receiver shall indicate Alarm Memory condition that
1
occurs immediately after the detector recognize a disarmed status by A.M. terminal input if
there shall be any alarm during armed period, and shall remain until re-armed.
The detector shall also contain a “D.Q. (Environmental Disqualification)” Red LED on the
Receiver. It shall illuminate when the beam strength shall be below an acceptable level due
to heavy fog, rain, snow or other changes in the installation site, continuing as long as the
beam strength is below an acceptable level.
POWER REQUIREMENT
The detector shall be capable of operating from a DC power source rated within the range of
10.5 – 30 Volts DC. The current draw (Transmitter + Receiver) shall be a maximum of 60
milli-Amps (mA) for model AX-350TF normal operating condition and a maximum of 78
milli-Amps (mA) during optical alignment for model AX-350TF. The current draw (Transmitter
+ Receiver) shall be a maximum of 62 milli-Amps (mA) for model AX-650TF normal
operating condition and a maximum of 80 milli-Amps (mA) during optical alignment for
model AX-650TF.
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. / N.O. selectable output. The detector shall signal the condition of Alarm
using a Form C Reed Relay with terminal strip connections. The detector shall also contain
a tamper switch (N.C.) that shall open when the cover is removed.
The detector shall contain D.Q. (Environmental Disqualification) output with a capable of
handling 28 Volts DC, 0.2 Amps (A) maximum N.C. / N.O. selectable, that shall send a
trouble signal when the beam strength shall be below an acceptable level due to heavy fog,
rain, snow or other changes in the installation site. The trouble signal output shall continue
as long as the beam strength is below an acceptable level.

SENSOR STABILITY
The detector shall remain stable even in high temperature conditions. The detector shall be
rated to operate within a temperature range of –30 degree F to +140 degree F (-35 degree C
to +60 degree C). 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 design shall protect the
detector from the effect of frost or snow. This 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.
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 one 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.
The detector shall contain 4 selectable beam frequencies (4 channels) to avoid unwanted
crosstalk that can occur when using multiple photo-beams for long distance or beam
stacking applications.

MIRRORS AND DETECTION PATTERN
The high-grade Reflective Mirrors shall create more sharply defined and precise infrared
beams to ordinary mirrors or lenses. The precise area of the detection field shall be specific
to each model. Model AX-350TF shall feature a detection range of 350ft. (100 meters)
outdoor and 700ft. (200 meters) indoor, with a Maximum Arrival Distance of 3,500ft. (1,000
meters). Model AX-650TF shall feature a detection range of 650ft. (200 meters) outdoor and
1,300ft. (400 meters) indoor, with a Maximum Arrival Distance of 6,500ft. (2,000 meters).
Easy optical beam alignment shall also be incorporated into the detector. The View finder
and LED indicator 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 (20 degrees = +/- 10 degrees).
MODEL
The Intrusion Detector shall be model AX-350TF or model AX-650TF. (with optional Heating
unit HU-1, requires 24 Volt AC/DC 430 milli-Amps. (mA) maximum), (with optional Back
cover BC-1), (with optional Beam Tower AX-BT)
