POWER SUPPLY GROUP OUTPUT
- Separate power supply outputs for panel/external loads and battery
recharge.
- Mains power signal output.
PROTECTION
1A T fuse on mains power input, 5A T fuse for battery protection, switching
regulator with thermal protection and current limitation.
BASIC I/O PANEL MODULE RAIK-A + RAIK-B (CPU A + CPU B):
ALARM OUTPUT
- Balanced alarm output for powered sounder in accordance with EN54-2;
supplies 27.5V (nominal) max. 5A for alarm (for short periods). The balance
is obtained with end of line resistance of 4.7 Kohm ¼ W.
- Service alarm output, available on free power contact of 5A / 30V=.
- Service alarm output, with retractable positive. When in standby state, it
supplies voltage of 27.5V (nominal) which stops when the alarm comes on.
The maximum current which can be picked up from this output must be in
accordance with the specifications indicated for the power supply group.
The alarm outputs may be deactivated from the main panel using the
appropriate command key.
FAULT OUTPUT
- Fault output on relay normally excited, can be selected as free contact N.C.
or N.A. able to commutate max 1A a 30V=.
The output may be deactivated from the main panel using the appropriate
command key.
PROGRAMMABLE OUTPUTS 1-6
Programmable electronic outputs 1-6. They repeat the state of the first 6
programmable outputs on the panel. Outputs 1-4 can be selected by jumpers
as an alternative to auxiliary inputs 1-4.
The outputs are usually open, close to negative if activated and can drive a
max. load of 0.2A at 30V=.
AUXILIARY OUTPUT
Programmable auxiliary relay output available in free power contact from
5A 30V=.
CONTROL/COMMAND INPUTS
Power system control input, supply ok/supply fault control input, supply fault
due to auxiliary panel control input, deactivation/external reset command
input, input for external 2
nd
access level activation (jumper).
AUXILIARY INPUTS 1-4
Auxiliary inputs 1-4, usable in panel programmable logic for controlling
personalised functions. They can be selected using jumpers as an alternative
to programmable local electronic outputs 1-4.
EXTENSION CONNECTIONS
- SPI local bus for connection of input and output concentrator modules.
- Serial line available with interface RS232 and/or RS485 for connecting a PC
for control/setting.
SIGNALING COMPONENTS
LED, alphanumeric display and buzzer to signal: states of operation,
functionality, power supply, deactivations, faults, alarms.
COMMAND COMPONENTS
- Keys on panel always enabled for immediate function of stopping buzzer and
alarm.
- Keys protected by 2nd access level for functions of deactivation, reset, test
and stopping outputs.
- PC connected to local serial port, with /command software installed.
PROGRAMMING COMPONENTS
- Display/LED/keys on panel active in configuration mode (protected at level 3,
can only be activated by opening the panel case).
- PC connected to local serial port, with CFGRAIK configuration software
installed.
