3. INSTALLATION

3.1 DIP Switches Setup

Remove the 2 detector's bottom covers (see Figure 3, steps 4-8) to gain
access to the DIP switches. Set the DIP switches, according to Table 1:

Alarm relay
(EN

* Switching from OFF to ON resets the detector for a stabilization

period of 60 sec. and causes the detector to re-adapt to its
current surroundings. Remain at a distance of at least 0.5 m (1.5
ft.) from the detector to prevent disruption of this process.

** Use ON for EN approved control panels / installations. However,

many installers prefer not to have the ALARM relay opened on a
masking event.

Table 1 – DIP Switch Setup

OFF: Motion and masking alarm LEDs

is disabled (OFF). Can be enabled by
TST input (Active "low")
ON: Motion and masking alarm LEDs
is enabled (ON).
OFF: Motion alarms are always
enabled (24 hours).
ON: Motion alarms are enabled only
at dark (night).

ON: AM on
OFF: AM off

*
OFF: masking event reported to panel
as TROUBLE (Trouble relay opens).
ON: masking event reported to panel
as TROUBLE and ALARM (EN
standard). Trouble and Alarm relay
opens at the same time.

3.2 Installation

Bracket installation (see figure 3) – firmly fix the bracket on a stable
wall or pillar. The orientation of the fixed bracket should be as parallel
as possible to the surveyed ground surface.

3.3 Wiring

Perform wiring (see figure 3, step 8 - 10)

3.4 Adjustments

Adjust detector's horizontal and vertical angles (see Fig. 4, steps 1 - 6),
according to the surveyed ground surface and close the detector, as
shown in Fig. 3, steps 7 - 12.
The vertical angle indicator position for various installation height and
coverage distance combinations is detailed in Table 2 (the
information refers to a relatively flat surveyed area. however, in any
case the vertical adjustment should be verified by walk-test).

3.5 Test

A. Set the detector in Walk-Test mode, by setting DIP switch 1 (LEDs

ON/OFF) to ON position (see Fig. 3, steps 10 and 11), or activate
the remote TST input by connecting it to GND.

B. Walk into the detector's field of view at the expected far edge of the

coverage area. Verify that each time your motion is detected the red
LED lights for 2 seconds and the control panel receives the alarm. If
required, perform detector's horizontal / vertical readjustments.

Important! Instruct the user to perform walk test at least once a
week, to verify proper operation of the detector.

C. Place a piece of cardboard on the detector’s front side, to

deliberately mask the optical window. After 2 minutes, the yellow
LED should light (see Table 3) and the alarm control panel should
receive the masking alarm.

D. Remove the masking from the detector’s front side. The LED

should extinguish (after about 30 seconds).
