4.4 Enrolling AML Devices
Addressable Multiplex Loop (AML) devices use a 2-wire connec-
tion for power and communication to and from the control panel.
All detectors are designed for low power consumption to make
for an efficient system.
For information on AML wiring, please see 2.9 ”AML Device
Wiring’.
Enroll the AML devices after all PC4108A, PC4164 and PC4116
modules have been enrolled.
Programming the PGM Terminal for an AML Loop
Ref #: [001400]
To enroll addressable multiplex loop (AML) devices, you must
first program the PGM terminal you have selected for the loop.
Perform the following:
1. Enter Installer’s Programming and enter reference number
[001400].
2. To select PGM1 for AML devices, scroll to ’PGM1 AML?’
and press [*]. The option will toggle to Yes.
3. To select PGM2 for AML devices, scroll to ’PGM2 AML?’
and press [*]. The option will toggle to Yes.
NOTE: Do not turn off the PGM AML toggle option unless all AML
devices have been removed from the loop (see ’Removing AML
Devices’).
To Enroll an AML Device
Ref #: [00140300] for PGM1
Ref #: [00140400] for PGM2
NOTE: All AML devices must be connected before they are enrolled.
To enroll the device, perform the following:
1. FOR DEVICES TO BE ENROLLED ON PGM1: Enter
Installer’s Programming and enter reference number
[00140300].
FOR DEVICES TO BE ENROLLED ON PGM2: Enter
Installer’s Programming and enter reference number
[00140400].
2. Enter the 5-digit serial number on the detector to be enrolled.
3. If the correct serial number was entered, the panel will allow
you to select the zone that the addressable detector will be
assigned to. Any zone from zone 001 to 128 on the PC4020 can
be used as an AML zone. If the detector is not connected to the
PGM terminal, the zone will not be enrolled. Do not use zones
designated for Access Control.
Repeat from Step 2 until all AML devices have been enrolled.
If the zone serial number is already programmed into the panel,
the panel will display the message ’Already Enrolled’ on the top
line of the LCD and the serial number on the bottom line of the
LCD for three seconds. The panel will then display the zone
assignment for the device. This allows for the reassignment of an
existing zone or to verify programming.
NOTE: Only the AMS-220/220T devices may be defined as fire
zones. Do not program other AML devices as fire zones.
AML Key
Ref #: [001401]
IMPORTANT NOTE: To ensure system security, the AML Key
must be programmed when using AML devices.
The AML Key is a 2-digit code that acts as a security lock for the
AML detectors. Once you have enrolled all AML zones, you must
change the AML Key from [00] to another 2-digit number (01-
FF). When the AML Key is changed, the panel broadcasts the
new code to each addressable device. Any device added to the
system with a AML Key other than the one programmed or the
default [00] will not function.
When an addressable device is deleted, the panel reprograms the
device’s AML Key to 00. This allows the device to be re-enrolled
on another system.
Moving AML Devices
To another zone on the same loop
1. FOR DEVICES TO BE MOVED ON PGM1: Enter
Installer’s Programming and enter reference number
[00140300].
FOR DEVICES TO BE MOVED ON PGM2: Enter
Installer’s Programming and enter reference number
[00140400].
2. Enter the device’s 5-digit serial number. The keypad display
will read ’Already Enrolled [serial number]’ to indicate that
the device has already been enrolled.
3. After three seconds, the display will indicate the device’s
zone assignment. Enter the new zone number. Any zone from
zone 001 to 128 on the PC4020 can be used as a AML zone.
4. The zone definition and attributes must also be programmed
for the new zone.
To another zone on a different loop
When moving devices to another loop, they must be deleted from
the first loop by following the instructions in ’Removing AML
Devices’ (see below). The device’s serial number can then be re-
entered on the other loop as indicated in ’To Enroll an AML
Device’ (see above).
Removing AML Devices
Ref #: [00140301] for PGM1
Ref #: [00140401] for PGM2
When removing AML devices, they must be deleted from the
loop. If the device is not deleted, its AML Key will not be reset to
[00].
To remove an AML device from the system, perform the follow-
ing:
1. For devices to be deleted from PGM1: Enter Installer’s Pro-
gramming and enter ref# [00140301].
For devices to be deleted from PGM2: Enter Installer’s Pro-
gramming and enter ref# [00140401].
2. The display will read ’Serial# [ ]’ on the top line of the dis-
play and the zone label on the bottom line of the display. Use
the [<][>] keys to scroll to the zone to be deleted then press
[*]. The bottom line of the display will then read ’Zone
Deleted’.
3. To delete all AML devices from the selected PGM output,
select Default AML. The panel will display ’Confirm Default
Press [*]’. To delete all AML devices on the selected PGM,
press [*].
