JA-14K(R) Security System Control Panel
16 / 72
MNX22101
The JA-14K(R) type is more suitable for wireless systems or also as a hybrid system. When planning the
configuration of a wireless control panel, do not forget to include the radio module(s) in the consumption.
Parameter
JA-14K(R)
Maximum permanent current from BUS
400 mA permanently
(1000 mA for 5 min)
Maximum permanent current for 12 hrs backup
125 mA
(with 2.6 Ah backup battery)
Calculation of BUS current according to the control panel HW configuration:
5.5 Power supply requirements
A security system which has to comply with security grade 2 has to backed up by a backup battery for 12 hrs
(according to EN 50131-1) during a mains power failure and it also has to be fully charged 72 hrs (according to
EN 50131-1) after mains power recovery and be ready to back the system up again.
To comply with this requirement it is necessary to ensure that the backup battery capacity is adequate for the
required time, see the following example. The nominal capacity of the battery should be checked by a test , see
technical specifications CLC/TS 50131-7, system testing.
Calculation of maximum permanent current taken from system BUS according to the backup battery capacity:
JA-14K control panel
, for 2.6 Ah battery
(calculation is valid for 80% of battery capacity)
2.6 Ah
* 0.8 / 12 h = 0.17 A
(according to the capacity - maximum current for 12 hrs)
Imax = 0.17 A – 0.05 A =
0.12 A
(subtract the control panel self-current 0.05 A)
The current taken from each BUS output terminal is shown in the N-Link SW in the Diagnostics tab on line 0
where the control panel is. It is necessary to take consideration of the shown current especially when
the JA-111R module is used (wireless control panel) connected to the special RJ connector so also add the
current of this module. This current is compared with a calculated current and it determines if the backup battery
capacity is adequate to norm requirements for system backup time. If the measured current is higher than the
calculated one, the backup battery should have a bigger capacity.
6 Use of wireless devices
In the JA-10 system you can use wireless device of JA-1x series and some of JA-1xx devices. The control panel
must be equipped with at least one JA-111R radio module, a maximum of 3 radio modules can be used in
system.
When installing individual device observe the instructions in their manuals.
