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.

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

2.9 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

provide 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 (pro-

vided that the output is programmed as Command Out-

put #2). Typically, this output is used for providing

power to latching type devices that require a power

interruption in order to reset.

2.10Telephone Line Wiring

The telephone terminals provide connections to the

incoming telephone lines for central station reporting.

The wires from the RJ31-X jack must be connected in the

following manner:

NOTE: For proper operation, there must be no other

telephone equipment connected between the control

panel and the incoming telephone line (e.g. answer-

ing 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.

2.11Bell Output Wiring (BELL

and BELL

)

These terminals are used for powering

bells, sirens or other devices requiring

steady output voltage on alarm. The

panel can provide up to 2A short-term

or 700mA long-term current. The out-

put is supervised. A trouble condition

will be generated when the bell con-

nection is lost. If no bell or siren is

being used, connect a 1000Ω resistor

across the BELL+ and BELL- terminals

to eliminate a trouble condition.

To ensure proper operation, the wire length of the bell

loop must be considered.

Consult the following chart to determine the maximum

wire length for the bell loop with respect to current. The

values reflect the use of a 30 watt siren.

To increase the length, double up on wire. For example,

when using 22-gauge quad, use two conductors for the

Bell+ connection and two for the Bell-. This effectively

doubles the maximum distance.

For UL residential installations, when a bell or siren is

used for fire signaling with a pulsed cadence, it must be

connected between the AUX+ and BELL- terminals. To

maintain bell circuit supervision, do not connect more

than one device to the BELL- terminal. A fire bell or siren

used for this application must be UL Listed and have a

current consumption of 400mA or less (e.g. Wheelock

MT-12/24-R).

NOTE: For Commercial Fire applications, you must use

the PC4010CF and the PC4702BP.

2.12Earth Ground Wiring

The cabinet should be earth grounded using the ground-

ing kit supplied. Ensure that the connection from the

cabinet to the metallic cold water pipe or earth ground-

ing rod is made with minimum 14-gauge solid copper

wire.
