Specifications

26 INTEGRA 128-WRL SATEL
The INTEGRA 128-WRL control panel must be supplied with 18 V (±10%) alternating
voltage. Use the transformer secondary winding to supply the mainboard. It is recommended
that at least 40 VA transformer be used.
The transformer should be permanently connected to the 230 V AC mains. Thus, before you
set about making the connections, make yourself familiar with the electric system in the
facility. Make sure that the circuit you choose for powering the control panel will be always
alive. The power supply circuit should be protected with a proper safety device.
A 12 V lead-acid sealed battery should be connected to the control panel as an emergency
power source. The battery capacity must be adequately selected to match current
consumption in the system. According to CLC/TS 50131-1 Grade 2, the battery must ensure
operation of the system without mains supply for 12 hours. It means that in case of the
system which fully utilizes the capacity of control panel power supply unit (2 A) a 24 Ah
battery must be used.
Note: If the battery voltage drops below 11 V for longer than 12 minutes (3 battery tests), the
control panel will indicate battery failure. When the voltage goes down to approx.
9.5 V, the battery will be disconnected.
3.11.1 Power supply connection procedure
1. Deenergize the 230 V AC circuit to which the transformer is to be connected.
2. Connect the 230 V alternating voltage wires to the terminals of transformer primary
winding.
3. Connect the terminals of transformer secondary winding to the AC terminals on module
electronics board.
4. Connect the battery to the dedicated leads (red one to the battery “plus”, black one to
“minus”). The control panel will not start after connecting the battery alone. Included
in the control panel set are adapters (matching connectors) for connection of battery with
twisted cable ends, therefore the battery cable ends should not be cut off.
5. Turn on 230 V AC power supply in the circuit to which the transformer is connected.
The control panel will start operating.
The above mentioned power-up sequence (battery first, 230 V AC mains after) will permit
proper operation of the power supply unit and control panel electronic protection circuits, thus
preventing defects of the alarm system components which might be caused by possible
installation errors. Modules fitted with their own power supply should be started in the same
way.
Caution: Should a situation occur when total disconnection of control panel power supply is
necessary, disconnect the mains first and then the battery. When reconnecting the
power supply, follow the above described sequence (first the battery, then the
230 V AC mains).
3.12 STARTING CONTROL PANEL
When the battery is connected and power turned on, the control panel will start. After power-
up, the control panel start is proceeding in two stages:
1. First, the STARTER program starts, checking the control panel firmware for possible
damage. If no error is detected, the STARTER launches the control panel program.
If an error is detected in the control panel program, the message "Load correct program to
the control panel" will be displayed on LCD keypads and the STARTER program will be
waiting for a new program from the computer. A program error may only occur when the
procedure of control panel firmware updating is disrupted by disconnecting power supply.
