Addressable Loop Response Time
The overall system response time for devices on the AML
loop depends on how many devices are on each loop.
The response times below include three factors:
•input debounce time
• addressable reporting and confirmation time
• processing time required by the panel to activate the
output
Response Time (seconds)
Response Time = 1.348 + (0.036 x # of zones)
Response Time = 1.348 + (0.036 x # of zones)Response Time = 1.348 + (0.036 x # of zones)
Response Time = 1.348 + (0.036 x # of zones)
Use this formula on the PGM with the greater number of
zones to find the loop response for both PGMs.
Addressable Loop Current Calculation
Each addressable multiplex loop can draw a maximum of
170mA of current from the main panel. In order to deter-
mine the amount of current required for the AML loop,
complete the following chart:
When more AML devices are added to a single loop, the
current draw increases. The loop wire length must be lim-
ited to the following distances depending on the total loop
curent:
Addressable Loop Wiring
AML devices can be
home-run, connected in a
daisy chain, or T-tapped.
Wire the AML loop
according to the follow-
ing diagram:
This configuration is only
used for AML devices.
Please see the
Installation
Instructions
provided with each device for more informa-
tion regarding operation and wiring.
For longer wire
runs, you can split
the addressable
devices onto two
or more loops from
the COM and
PGM terminals.
For example, 32
AMB-300 detectors (2.5mA each) take 80mA total. In one
18AWG wire run, this would allow a maximum length of
720 feet (220 m). If you split the 32 devices into two wire
runs of 16 detectors each, using 18AWG wire, each wire run
could be 1736 feet (529 m) long. See the diagram above.
NOTE: No end-of-line resistors are required when installing
these devices.
NOTE: Once the devices are connected, the PGM terminal
must be configured for AML operation and each device
must be enrolled. See Section 4.4 ’Enrolling AML Devices’
for instructions.
NOTE: Do not use shielded wire runs in parallel with each
other. Do not run either AML wire run in parallel with the
Combus. Maintain minimum 2” separation between all
AML wiring and Combus wiring.
2.10 Wiring Powered Devices (AUX, SAUX+)
AUX – Auxiliary Power
These terminals can be used to power motion detectors,
glass break detectors and other devices requiring power.
The AUX (positive) and GND (negative) terminals can pro-
vide up to 500mA of current.
SAUX+ – Switched Auxiliary Power
This terminal provides positive power (12V
DC
) and can be
de-energized via the [*][7][2] keypad command (provided
that the output is programmed as Command Output #2).
Typically, this output is used for providing power to latch-
ing type devices that require a power interruption in order
to reset.
2.11 Telephone Line Wiring
The telephone terminals provide connections to the incom-
ing telephone lines for central station reporting. The wires
from the RJ-31X jack must be connected in the following
manner:
NOTE: There must be no other telephone equipment con-
nected between the control panel and the incoming tele-
phone line (e.g. answering machines, fax machines,
telephones, etc.). Ensure that plugs and jacks meet the
dimension, tolerance and metallic plating requirements
of 47 CFR Part 68 Subpart F.
