buzzer for communicating beam interruptions (for the first 30 minutes after power-up of the
device). One short beep corresponds to interruption of each beam. For example:
a simultaneous interruption of 3 beams will generate a sequence of 3 short beeps; 4 beams – 4
beeps, etc.
3. Installation
Note: Bear in mind during installation that the barrier should not be directly exposed to water (e.g.
rain, sprinklers).
Be particularly careful during installation so as to prevent direct sunlight from entering into the receiver
(see Figure 4), since this may interfere with the device operation and cause triggering of false alarms.
Figure 4. Optimum positioning of the barrier with respect to the sun (T – transmitter, R – receiver).
The barriers can be mounted with their power supply leads facing either up or down. However the
mounting position in which the cables of transmitter and receiver are oppositely directed (i.e. the
cables of transmitter are upward-directed, and those of receiver downward-
directed, or conversely
–
see Figure 5) is not allowed.
Figure 5. Installation of barrier cabling.
Whenever it is necessary to connect several barriers together (either in parallel or in series), it should
be borne in mind that transmitters and receivers must be suitably positioned (see Figure 6).
