Power Supply Module
NTM2402-1
Description
The Power Supply Module NTM2402-1 serves for the
safe supply of devices, which need a nominal voltage of
24VDC. The typical fi elds of application include fi re de-
tection systems and extinguishing controls or any other
applications requiring a safe power supply.
The output voltage of the integrated switched-mode
power supply is current-limited and short-circuit-protec-
ted.
The optional stand-by batteries guarantee an uninterrup-
ted power supply in the event of a mains power fault.
At a typical charging time of 24 hours, batteries with a
maximum capacity of 60Ah can be charged. The inte-
grated protection against total discharge and the tem-
perature compensated battery charging are the basis
for a long battery life.
The battery monitoring according to EN 54-4:2006 in-
cludes the periodical measurement of the battery volta-
ge under load and the internal resistance of the battery.
The integrated earth leakage monitoring of the module
can be deactivated for special applications.
The module is designed for installation into a power sup-
ply housing. For that purpose, two different housings
are available. At the front of the housing, seven light
emitting diodes indicate the operation as well as pos-
sible causes of faults.
By means of the integrated test function, a functional
check can be performed and the present value of the
internal resistance of the battery can be read out. With
that, the maintenance of power unit and batteries is es-
pecially easy and timesaving.
• Uninterrupted power supply for
devices with 24VDC, max. 2.3A
• Current-limited, short-circuit-
protected output
• Monitoring of battery charging and
internal resistance of the batteries
• Installation into wall-mount cabinet or
19“ housing
• Status display at the housing front
• Complies with EN 54-4:2006

Power supply housings
The wall-mount cabinet NTG24-1 provides space
for the power supply module as well as for the in-
stallation of 2 stand-by batteries with 12V/max.
45Ah, one Relay Module RL58-1 or RL58-2 and
one Multi Module MEA244-1/E. In this case, the
power supply module serves as power supply for
the multi module and the loads that are actuated
via the 4 outputs.Furthermore, via the inputs of
the multi module, fault messages can be forwar-
ded to the fi re detection control panel.
If required, further modules can be mounted in
the cabinet door.
Thanks to the sophisticated design of the Po-
wer Supply Front Panel NTG24-1CE, it can be
mounted either on a 19“ pivoting frame or on the
mounting plate of a switch cabinet.
In both cases, the optional stand-by batteries
are accommodated in the interior of the switch
cabinet.

Specifi cations
In addition to the power supply module, the Power Sup-
ply Front Panel NTG24-1CE can also accommodate a
Relay Module RL58-1 or RL58-2.
Both housings are made of powder coated sheet steel.
At the front of the housing, the built-in display and ope-
rating board allows the signalling of the most important
operating conditions as well as the resetting of the in-
ternal buzzer.
The display and operating elements can be labelled in
the respective national language by means of the sup-
plied insertable labelling strips.
