Wiring Connections - ADEMCO 4278EX Installation Instructions Manual

G. Mirror Masking:
The masking strips that have been supplied are designed for application to one or more
mirror segments to produce a protection pattern that suits the particular requirements of
the protected area. Simply peel off the appropriate pressure-sensitive adhesive strip(s)
and apply over the desired mirror segment(s). Individual masking strips have been
provided for each of the mirror segments on the wide-angle mirror. Two strips are
provided for masking multiple segments of the long range (curtain) mirror. Each mirror
segment that is masked results in the elimination of one zone of protection from the
coverage pattern. By masking appropriate segments of a mirror, you can adjust the
coverage to suit the area to be protected, or to eliminate coverage from areas where you
anticipate environmental disturbances that might reduce the PIR's stability (a heater or
other heat-producing object, for example).

WIRING CONNECTIONS

Bring all wires in through the PIR's wiring entry near the terminal block and make
connections as indicated in Diagram 8.
Signal Processing:
With the Mode Select Switch in the NORMAL position (see Diagram 8), the signal
processing circuitry of the PIR provides maximum immunity against unwanted alarms
caused by environmental disturbances, external electrical sources, heaters, etc. The
detector will then normally signal an alarm within 3 to 4 steps, since the processing logic
requires more complex motion than just a momentary event. When the detector verifies
an intrusion, it signals the control and lights the LED (unless disabled).
With the Mode Select Switch in the INSTANT RESPONSE position, the delay
involved in signal processing is eliminated. An instant alarm response (and lighting of
the LED unless disabled) is provided when an intruder enters any single protective zone.
Use instant response mode when the long range mirror is installed, or where the
detector is used to protect narrow corridors, or where single protective zones are
directed through doorways or room openings.
Connections:
See diagram 8 for connections, which should be made as follows:
1. Polling loop (+) and (-) terminals: Connect these terminals to thessytem polling
loop. Observe polarity.
2. External sensor terminals: Connect these terminals in a series of loop to external
N.C. sensors that can be assigned to any zone response used by the PIR.
NOTE: This loop is assigned to a zone in the control's programming in the fields,
described as "Designate Right Loops for Polling Zones".

DIAGRAM 8. WIRING CONNECTIONS AND SWITCH SETTINGS
Refer to the installation instructions for the control communicator regarding the
polling loop. ID numbers, and enabling of tamper detection (a pre-connected
tamper switch is activated by removal of the unit's cover).
SELECTING AN ID NUMBER
Make all identification number selections by arranging the switches on the circuit board.
The ID number is equal to the sum of the switch values in the "OFF" position. Each
switch has a different value and should be set according to Table:

TESTING
IMPORTANT: Wait at least two minutes after applying power before attempting to walk-
test unit.
Testing of the detector should be conducted with the protected area cleared of all
people. In some business establishments, it may be convenient to do this after the
business is closed. The protective system's control should be disarmed during the
procedure to prevent reporting unwanted alarms.
Zone Locator
The Zone Locator (not supplied) permits the actual zone coverage patterns provided by
the detector to be accurately determined during installation or subsequent testing.
1. Remove the detector's cover.
2. Install the Zone Locator as follows (refer to Diagrams 9 and 10).
A. Locate the foam cushion at the rear of the detector element and rest the upper
edge of the Zone Locator against its surface as shown at "P" in Diagram 10.
B. Pivot the Zone Locator into place.
C. The upper (rubber bumper) portion should be flat against the foam cushion and
the lower (red spot) portion should be flat against the detector element.
With the Zone Locator temporarily installed as described above, the image of the Zone
Locator's reflective red spot (see Diagram 11) can be seen reflected in various facets of
the detector's mirror by a person looking back at the unit from the zones of protection.
When the red spot is visible in a particular portion of the mirror, the viewer is
within that particular protection zone.
NOTE: In dimly lit areas, a flashlight aimed at the mirror from the viewer's position will
make the red spot more visible.
Remove the Zone Locator when testing is completed and replace the detector's
cover.
