GENERAL
The GR-24/12-1 is a stabilized power supply
continuous operation that provides a voltage of
12V DC to independent devices (according to
the device). The output network is stabilized to
the 13,5 V DC with a maximum current 4Α.
It provides continuous power to the external
devices, with the incorporated power supply as
long as the mains power supply does not fail.
In case of mains failure the device gives power
to the external devices from the included
battery.
In fire detection systems it is used when the
detector’s power consumption is greater than
the maximum panel that the panel can provide.
It is also used to power any other device that
require 12 V DC and autonomous operation.
The device includes the SW1 switch which
activates or deactivates the output as long as
you desire.
The green indication LED indicates the output
status. The jumper LOCAL/REMOTE is also
used according to the input REMOTE in the
respective terminal blocks and concerns the
output status. If no external device to control
the GR-24/24-1 output is connected then the
jumper must be placed in pins 1-2 and the
output control can be done with the switch
SW1. If you want to control the output from an
external device,
then the jumper must be placed in pins 2-3,
the switch SW1 in the ON position
and the
control signal must be connected to the
REMOTE terminal blocks. In the input, when
the voltage exceeds 6V, then the GR-24/12-1
output is active and when the voltage remains
under 6V the output remains deactivated.
Autonomy calculation example
The autonomy of the device is proportional to
the battery (i.e 7Ah for GR-24/12-1 and
inversely proportional to the consumption of
the number of detectors. If you want to connect
10 devices that consume 200mA from the GR-
2 4 / 1 2 - 1 , t h e n t h e a u t o n o m y w i l l b e
approximately 6 hours, and if we want to
connect 20 devices, the autonomy will be
approximately 3 hours. In this way we can
calculate how many detectors will connect to
the power supply and how much autonomy we
have. The device has an electronic fuse that
protects its output from short circuits that could
cause serious problems.
ΑΤΤΕΝΤΙΟΝ!!!
1. Operations for installation, maintainance or
testing must be done by authorized personel
only.
2. The device must be connected to the mains
power supply thru a fuse dependent by the
total amount of the line’s power load.
When activated the
electronic safety output is disconnected
permanently and for restoring the functioning of
the device will be restored in a shortcircuit and
to disconnect the network and the battery for a
few seconds.Immediately after can function
normally.
