DTM System FOCUS User guide

1. Principle of operation.
Photocell includes transmitter and receiver (fig.1).The transmitter emit a coded Irfrared
(IR) signal , invisible to the naked eye.Obstacle appearance (e.g. car) on photocell working area
produces a detection signal on receiver output. Receiver has NC and NO type output contacts.
Photocell is destined to work in gate automation system as external element. Built-in signal
lampsin both,receiver andtransmitter,suppliedwith 24V,fulfill signalfunction ingate system.

•dimensions(szer. x głęb. x wys.) 62x28x100mm
•Mounting surfacemounted,IP54
•Outputcontacts typuNO i NC
3. Photocell mounting.
For proper funcionality photocell must be mounted coaxial, 40-60 cm off the ground,
receiver and transmitter distance not less than 1 m . Because of photosensitive elements it is
recommended to mount receiver on less sun exposure side. Both receiver and transmitter must
be mounted vertically. Terminal blocks and humidity carrying openings should be in the
bottom part of enclosure. Proper receiver and
transmitter adjustment is facilitated by
receiver's diode RX. RX diode lights when
transmitter ray reaches receiver. Both
enclosures should be mounted by 2 (diagonal
mounting) or 4 screws available in set. To scale
down photocell sensitivity (minor receiver and
transmitter distance) it is recommended to
dismounttransmitter's lens.

4. Photocell connection
Photocell cooperates with most of gate controllers available on market. It is
recommended to do electrical installation and photocell mounting by qualified person.
Connect photocell according to fig. 3 scheme. First find 24V AC/DC clips (polarity is not
important!) intended to power supply, in gate controller. Connect power supply to receiver
and transmitter. When power is on red LED’s (POWER) in receiver and transmitter light. Next
connect gate controller input to photocell's receiver output (RX pins: 1,2 or 2,3). Pay attention

to controller's input type (NC or NO). Photocells usually works with NC mode in gate automatic.
It is recommended to connect signal lamps parallely, supplied with 24V AC/DC, current
consumptionab. 80mA.
5.Receivingtests
After photocell connection is done, it is recommended to check receiver (RX) reaction on
Inrfarared signal breaks. Gate automation systems must be tested conformity to EN 12445
standard. Photocell test: 1. Supply power to receiver only and check if RX diode out. 2. Supply
power to transmitter and chceck if RX diode light. 3. Displace roller of 5 cm diameter and 30 cm
length, to break perpendicularly optical axis between receiver and transmitter. First in the
vacinity of transmitter TX, next in the vacinity of receiver RX, next in the middle of distance
between them. In all cases photocell should switch from standby to alarm mode, which is
signalizedby RXdiode wane.

6.Warranty.
DTM System checks all the devices before shipping. The warranty time is 24 months
from the selling date. This time is counted according to the warranty label. The manufacturer
will fix all the problems which come because of his fault. Non functionaling device should be
delivered back to the distributor with short problem description.The cost of mount/dismount is
covered by user.The warranty do not cover: batteries in the remotes, faults caused by improper
usage, user self repairs and adaptations, lightning strikes, over voltages or short circuits in the
mainssupply.Appropriatelegal actsregulates detailsof thewarranty.
