If programming manually, be sure that other polling loop sensors are not activated

so that they cannot send a signal to the control while this PIR is being programmed

(mask PIRs, don't open/close doors, etc.).

¨ IMPORTANT Ã

To be sure that other polling loop devices are not activated when entering ser-

ial numbers manually, power the system down, disconnect the polling loop at

the control, power back up again, and immediately enter the program mode.

Then proceed to Step 1 (below). Remember to re-connect the polling loop

when programming is complete, powering the system down first.

To either manually enter or "learn" the unit's serial number:

1. Enter

93 Zone Programming mode.

2. Enter the Response Type and other zone information for the PIR, pressing [ ]

to advance from prompt to prompt.

3. At the "Input Type" prompt, enter "6" for SL (Serial Polling Device) and press [ ].

4. At the "Learn S/N?" prompt, enter (Y)es.

5. At the "Input S/N" prompt, either enter the serial number manually (and a "1" for

the loop number), or fault the PIR being learned (the keypad will "beep" to

confirm signal). Wait 3Ð6 seconds and fault the PIR again (the keypad should

beep again to confirm).

The PIR should now be learned. A "1" should appear under the "L" on the zone

summary screen. (If an "N" is displayed, the PIR is not learned.)

6. Press [ ] to continue programming zones.

TESTING

IMPORTANT: Wait at least two minutes after applying power before attempting

to walk-test unit.

Before testing the detector, the protected area has to be clear; if more

convenient, the walk test can be done after close of business.

The protective systemÕs control should be disarmed during the procedure to pre-

vent reporting unwanted alarms.

Walk Test

Place switch #2 to the WALK TEST position, replace the front cover, and then

walk through the protective zones. The LED will light whenever motion is detect-

ed. Be sure that the Mode Select switch #1 is in the same position in which it will

be used. For example, place it in the INSTANT position if the long range mirror

is installed. See ÒSignal ProcessingÓ above.

BE SURE TO PLACE THE WALK TEST SWITCH IN THE "DISABLE" POSITION

AFTER THE INITIAL WALK TEST IS COMPLETED.

Subsequent periodic walk tests must be done in conjunction with the indicators

of the associated control panel.

The absolute range of all Passive IR units is subject to variation because of dif-

ferent types of clothing, backgrounds and ambient temperature. For this reason,

ensure that the most likely intruder routes are well within the PIRÕs protective

zones and that walk-testing is carried out along these routes.

TO THE INSTALLER

Regular maintenance and inspection (at least annually by the installer) and fre-

quent testing by the user are vital to continuous satisfactory operation of any

alarm system. The installer should assume the responsibility of developing and

offering a regular maintenance program to the user, as well as acquainting the

user with the proper operation and limitations of the alarm system and its com-

ponent parts. Recommendations must be included for a specific program of

frequent testing (at least weekly) to insure the systemÕs operation at all times.

MAINTAINING PROPER OPERATION

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.

2. Units should never be re-aimed or relocated without the advice or assistance

of the alarm 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 company.

4. Conduct Walk-Test frequently (at least weekly) for proper coverage by each

detector.

REMEDY

Locate source and reposition

detector.

Eliminate source of motion.

Ensure that proper polarity and

adequate voltage is supplied,

and that wiring is intact (no

opens or shorts) and connec-

tion is secure.

Check for presence of 8-11VPP

at terminals of the PIR. If too

low, polling loop run to control

may be too long for the wire

gauge used,or polling loop cur

rent drain may be excessive.

Increase wire gauge or add No.
