Wiring Diagram
Wiring
AUX WIRING: Min 22AWG Max 16AWG. (Depends on
length and Current consumption). For wire/cable size,
a maximum of 5% voltage drop at the terminals of
the powered device has to be observed.
MODULE NETWORK WIRING: Recommended Belden
9842 or equivalent. (24AWG twisted pair with
characteristic impedance of 120ohm or CAT5e / CAT6
are also supported for Data Transmission when using
ground in the same cable. Do not use extra wires to
power devices.)max 900m (3000ft).
Battery Characteristics
BatteryType to be used: VRLA (valve regulated sealed
lead acid type rechargeable battery)
Recommended Battery: Yuasa model:
NP7-12, 12V,7Ah (www.yuasabatteries.com)
Nominal Voltage: 12V
Nominal Capacity: 7Ah
Battery Maintenance: It is recommended to replace
the battery every 3-5 years.

PGM Connection
Upon successfully completing the initial
registration with any System Controller, the
outputs operate in Online Mode. While in
online mode, the 2 outputs function as PGMs
and can be used to activate bell sirens,
lighting circuits, door locks, relay accessory
products and other automation points.

The 4A Intelligent Power Supply should be supplied by a
dedicated electrical power source rated for a minimunm 5Amp
load and have a dedicated circuit breaker. Connect the Intelligent
Power Supply module to mains input via a USA to C7 90 degree
2M SPT-2 x 2C 18AWG cable.

Until connection to any System Controller is established, the outputs operate in
Offline Mode. While in offline mode, the 2 outputs function as status outputs.
AC Fail Status Output:
The output relay contacts
disconnect (Normally Open)
when AC power is removed
and unit remains running on
backup battery power. Upon
restoring AC power, the output
relay will revert back to its
default state
(Normally Closed).
Outputs - Offline Mode
Battery Fail Status Output:
The output relay contacts
disconnect (Normally Open)
when either the backup battery
has been disconnected, or
when the Power Supply is
running on backup battery
power without AC power and
the backup battery voltage
drops below 11.75V. Upon
reconnecting a backup battery
with a voltage greater than
12.5V, the output relay will
revert back to its default state
(Normally Closed).
The outputs are shown to be connected to a DIN Rail 16 Input Expander
so the statuses can be externally monitored.
The address of the 4A Intelligent Power Supply is
configured via programming and will require reference
to the module serial number. The serial number can be
found on the identification sticker on the side of the
module.
Please refer the System Controller Manual for address
programming details.
CAUTION:INCORRECT
WIRING MAY RESULT IN
DAMAGE TO THE UNIT
Devices connected to other Modules
Inductive devices (such as electric locking
devices, solenoids, etc) connected to other
modules require a 1N4007 diode to be fitted as
close to the device as possible.
