General Description

IRIS PS72 is a power supply unit designed for back-up power supply of 
IRIS addressable fire alarm panel. The power supply is placed into a 
metal box suitable for building of a modular structure with the 
addressable panel and a second power supply unit. The access to the 
main board and the cable connections is secured with a key. 
The status of IRIS PS72 is displayed via a LED indication on the main 
PCB. The status of the power supply unit can be continuously monitored 
with enabling the option “External PSU Check” from the IRIS panel 
menus. When the option is enabled the panel will display a fault 
message “External Power Supply Fault

Periphery Device

 1-

PSU” in 

case of any trouble with the power supply. The respective trouble of the 
power supply is visualized with a blinking LED on the PCB.
At normal operation mode only “OK” green LED is blinking and all other 
LEDs are off. In case of main power supply (230V~) loss the “FLT” 
yellow LED starts blinking and “OK” green LED is off. In case of trouble 
with a Battery 1 and/or 2, the yellow LEDs at sections Batt1 and/or Batt2 
are blinking. A detail description of all LED indicators is performed at 
Item 2: IRIS PS72 Main Board - see on page 2.

IMPORTANT NOTES

• 

Warning! An appropriate di

s

connect device shall be provided 

as part of the building.

• Switch OFF the main power supply and the battery of the 
IRIS panel before installing the IRIS PS72 power supply unit!

• Use only the connection cables supplied with the equipment: 
red and black wires for connection to JP4 terminals; white and 
grey wires for connection to FLT terminals! Do not shorten or 
extending these cables!

• Make all the wiring observing the polarity of the connections 
following the presented connection diagrams. If after 
powering on the IRIS PS72, the LED “WRONG CONNECTION” 
is lighting on, switch off the power supply immediately and 
check the connection between the power supply unit of IRIS 
panel and terminals JP4 of IRIS PS72!

• If the LED “Hi Resist” for Battery 1 or 2 is blinking it is 
strongly recommended to change the batteries immediately!

• The cover is mounted to the box bottom with hinges fixed 
with dismountable rivets. The angle of opening of the front 
cover must not be greater than 110°!

ATTENTION: 

Read carefully this installation Instructions 
before installing the device!
