Indoor Photo-Electric Infrared Beam Barrier
Installation Instructions
,1752'8&7,21
IR-50 and IR-150 are pulse-modulated photoelectric infrared
beam barrier designed for indoor residential, commercial and
industrial applications. The system consists of a transmitter
producing a wide angle (IR-50) or concentrated (IR-150) invisible
infrared beam towards a narrow-angle receiver. Visible Beam
Locator light in the receiver (IR-50) or in the transmitter and the
receiver (IR-150), provide quick and easy alignment without
special tools or test equipment.
The transmitted beam is generated by 2 powerful infrared LEDs.
The 40
°
wide angle beam of IR-50 allows multiple receiver
installations using a single transmitter. The 6
°
receiver field of
view provides a large safety margin to prevent false alarms. Yet it
is narrow enough to eliminate reception of reflected beam. Internal
built-in optical filter prevents unwanted light penetration, other
than the infrared wavelength.
The system is immune to
fluorescent radiation, flickering
lights and indirect sunlight.
State-of-the-art electronic
circuitry provides protection
against RF interference and
supply voltage transients.
The transmitter emits an invisible
beam, to the receiver. When an
intruder crosses this beam
barrier, the receiver’s internal
alarm relay deenergizes.
IR-50 Transmitter & Receiver
Note: External view of IR-150
transmitter & receiver is similar.
The receiver’s walk test LED lights at the same time (when LED
selector is in Walk position, see par. 3.4). After crossing, the relay
again energizes and the LED extinguishes.

A. Select mounting locations / height for the transmitter and
receiver(s) so that an intruder will cross the beam(s). The
receiver and transmitter should be mounted facing each other,
and their angular back housing allow installation directly onto a
wall (surface mount), or in a corner. They may also be
flush-mounted using optional bracket SRF-201. (Fig. 5).
B . Prevent receiver’s lens exposure to direct sun light, to prevent
false alarm.
C . For maximum reliability, locate the receiver as far as possible
from fluorescent light or flickering lights.
NOTE: The transmitter unit is not sensitive to any of the above
disturbance sources and may be placed wherever desired.
