Visonic Inc. DUO220EAM Manual De Usuario
Increasing the vertical angle at a certain height will increase
the coverage range.
•
Do not install the DUO 220 in places where one of the two
detector circuits alarms constantly or intermittently, due to
environmental interference.
•
Special advice to DUO 220AM users: It is desirable to mount
the unit in locations where inadvertent approach to less than
1 m (3 ft) from the detector is unlikely to occur.
3.2 Direct Mounting
The unit can be installed directly on the wall or in a corner using
the mounting knockouts. Optional swivel brackets permit greater
flexibility when adjusting the coverage area (see Para. 3.3).
A. Loosen and remove the screw at the bottom of the case
the mounting knockouts. Optional swivel brackets permit greater
flexibility when adjusting the coverage area (see Para. 3.3).
A. Loosen and remove the screw at the bottom of the case
(Fig. 1) and then take the cover off.
B. Punch out the appropriate mounting and wiring knockouts in
the base.
Note: For wall surface mounting, use the two elongated
knockouts at the middle of the base. For corner mounting, use
two diagonally opposite knockouts at the angled sides of the
base (Fig. 3).

Terminal: TAMP (tamper switch)
Connect to: A normally closed 24-hour tamper zone of the
control panel.
Figure 3. Printed Circuit Board Layout
Details: When the cover is removed, the tamper switch opens.
C. Select the mounting location in accordance with the
guidelines in Para. 3.1.
Terminal: NC (alarm relay)
Connect to: Normally closed burglar protection zones of the
control panel.

D. Temporarily remove the PC board from the base. Take care
not to lose the fastening screw.
Details: Upon alarm or power failure, the output relay’s normally
closed contacts open.

E. Use the base as a template for marking the drilling points.
F. Drill the mounting holes and insert masonry anchors if

Terminal: TRB (trouble output)
Connect to: 24-hour trouble zone, parallel to an E.O.L. resistor
(see Figure 5).
Connect to: 24-hour trouble zone, parallel to an E.O.L. resistor
(see Figure 5).
G. Pass the wires through the punched-out wiring inlet(s) and
mount the base in place using two screws.
Details: The TRB open collector output will be grounded upon
detector malfunction or upon masking (DUO 220AM), causing
disturbance in the trouble zone of the associated alarm system.

disturbance in the trouble zone of the associated alarm system.
H. Seal all openings in the base with RTV to prevent insects from
entering the unit.
I. Remount the PC board and secure it with its vertical
adjustment screw.
Alternative: a buzzer or an interface relay may be connected
across the TRB output and the 12 VDC (+) terminals.
across the TRB output and the 12 VDC (+) terminals.
3.3 Optional Swivel Brackets
Terminals: 12 V (+) and (–)
Connect to: A power source within the range of 9 to 16 VDC.
Take care not to reverse the polarity.

The BR-1 is a general purpose swivel bracket used for vertical
and horizontal positioning of the DUO 220. With the BR-1, the
unit can be tilted down from 0° to -30° and swiveled 45° left or
right (see Fig. 4).

Details: It is advisable to connect the power source only after all
other connections have been completed and rechecked. Discon-
nect the AC mains from the alarm control panel and verify that
the voltage supplied to the detector is above 9 Volts with the
backup battery as the only power source.
