Sayfayı Yazdırby an amount that increases the farther the observer is from the unit. Although this image should not be used
for vertical alignment, it is useful, however, in panning the unit to obtain best horfzontal coverage and/or
avoiding direct view, by the unit, of heat radiators, heating and ventilating registers, direct sunlight, etc.
(Loosen the panning screw below the optical assembly while adjusting.)
When the desired aiming is obtained, tighten the panning screw firmly taking care not to disturb the align-

ment. Remove the Zone Locator LED, but leave its mounting screw In place.

Final Test:
Double-check all connections. Replace the front cover and secure holding screw. Walk-test unit with cover in
place. Test operation by walking through the protective zones and observing walk-test LED. If necessary to ob-
.tain desired coverage, adjust the unit to the left or right (by temporarily loosening the panning screw) or adjust
it up or down(via the vertical adjustment).
Test standby operation (Nos. 659 and 651 only) by unplugging the line transformer. Make sure that the battery
in the No. 659 or 651 has had a chance to charge for at least an hour before checking. The system should con-
tinue to operate with the transformer unplugged; however, the walk-test LED will not function. If the unit fails
to operate, the battery should be replaced (contact nearest Ademco Distribution Center).
Note: The absolute range of all Passive I.R. units is subject to variation because of different types of clothing,
backgrounds, and ambient temperature changes. For this reason ensure that the. most likely intruder routes
are well within the protective zones and that walk-testing is carried out along these routes.
Meter Test (if required, for analyzing problem areas):
1. Remove the detector's cover.
2 Connect a DC voltmeter (or multimeter), 3OK ohms per volt as follows:
a. Set the meter to its 2.5V.DC range.
b. Connect the meter's positive (+) test lead to the detector's TEST POST (located as shown in Diagram 6
or 9, depending upon the unit).
c. Connect the meter's negative (-) test lead to detector terminal 4.
3. Mask the detector's optics so that motion cannot be detected. (Note: Placing the optic's protective shipping
-
foam over the mirror will
not
provide sufficient masking. Use of a handkerchief or sheet of paper in front
of the mirror is suggested.)
The meter should indicate approximately 1.6V.DC (with a permissible normal fluctuation of approximately
O.lV.)
4. Remove the mask covering the optics, remain motionless and allow time for the meter to settle. Motion into
any of the detector's zones will cause the meter to deflect above or below the nominal level. A meter varia-
tlon of t 0.5 volt will trtp the unit, causing its LED to illuminate and its alarm relay to transfer.
a. (Nos. 650,651 Only): The plug-in transfprmer should be kept in its socket and continuous lPOV.AC supplied
to it so that the standby battery remains charged. Note: Loss of battery power will result in an alarm
signal.
b.(Nos. 65@6,651-6 and 65612EX, 65%12EX Only): The unit's DC source should have standby power
-
available for at least 4 hrs of operation during emergencies.
2 Units should never be re-aimed or relocated without the advice or assistance of the alarm service company.
3. The physical surroundings of the protected area should not be changed. If furniture or stock is moved, or
air-conditioning or additional heating is installed, the system may have to be readjusted by the alarm ser-
vice company.

4. Walk-tests should be conducted frequently (at least m@hly) to confirm continued proper coverage by each
detector.

MAINTAINING PROPER OPERATION AND COVERAGE:
In order to maintain the detector in proper working condition, it is important that the following be observed by
the user.
1. Power should be provided at all times.
