Important notes
• Warning! An appropriate disconnect device shall be provided as part of the building.
• Switch OFF the main power supply and the battery of the 41CPE118 panel before installing the 41ALM172 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 41ALM172, the LED "WRONG CONNECTION" is lighting on, switch off the power supply immediately
and check the connection between the power supply unit of 41CPE118 panel and terminals JP4 of 41ALM172!
• If the LED "Hi Resist" for Battery 1 or 2 is blinking it is strongly recommended to change the batteries immediately!
General Description
41ALM172 is a power supply unit designed for back-up power supply of 41CPE118 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 41ALM172 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 41CPE118 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: 41ALM172
Main Board
Mounting
