EN: Installation Sheet
Description
This document includes installation information for the
following expansion boards:
• 2010-1-RB Expansion Board with four relay outputs
• 2010-1-SB Expansion Board with four supervised outputs
Relay expansion board
The relay expansion board has four voltage-free relay outputs
each rated for 2 A at 30 VDC. Relays can be assigned to
detection zones or programmed for activation based on system
events.
Supervised expansion board
The supervised expansion board has four supervised outputs,
each providing 24 VDC. The supervised outputs can be
configured as sounder outputs, fire routing outputs, fire
protection outputs, or fault warning outputs, and can be
assigned to detection zones or programmed for activation
based on system events.
When configured as sounder, fire routing, fire protection, or
fault warning outputs, the control panel interface provides
indications and the available control options.
When configured as a general purpose supervised output
board, short and open circuit faults are indicated by the general
Fault LED and the Expansion I/O Fault/Disabled LED on the
control panel interface.
Installation
WARNING: To avoid personal injury or death from
electrocution, disconnect the control panel from the mains
power supply and batteries before installing this product.
To install the expansion board:
1. Unplug the power supply unit, the batteries, and any other
device cables connected to the control panel PCB.
2. Remove the holding screw and unclip and remove the
control panel PCB, as shown in Figure 1 (for two- and
four-zone control panels, unclip the PCB at each corner by
pressing carefully on the holding studs).
3. Install the expansion board into slot A on the left of the
cabinet and push the board firmly into place.
For two- and four-zone control panels refer to Figure 2,
item 1. For 8-zone control panels, evacuation panels, and
extinguishing panels refer to Figure 2, item 2.
To install more than one board, connect the INPUT and
OUTPUT connectors of each board (as shown in Figure 2)
before pushing the boards into the appropriate slots.
4. To install a supervised expansion board, configure the
power source (if required). See “Configuration”.
5. Replace the control panel PCB and reconnect all battery
and power supply cables.
6. Connect the expansion board in slot A to the control panel
PCB, as shown in Figure 3.
Wiring
Relay expansion board
To wire the relay expansion board, connect all devices to
OUT1, OUT2, OUT3, and OUT4 (NO, NC, and C). See
Figure 5.
Supervised expansion board
To wire the supervised expansion board, connect all devices to
OUT1, OUT2, OUT3, and OUT4. If required, connect the
external power supply to 24VIN and 24VOUT. See Figure 6.
Caution: Never use the auxiliary output to power expansion
boards connected to the same control panel as this might
damage the control panel hardware.
For Class B output installation:
All outputs require a 15 kΩ end-of-line resistor for termination.
If an output is not used, the 15 kΩ end-of-line resistor must be
installed across the unused output terminals.
For Class A output installation:
All groups of outputs (OUT1/2, OUT3/4) require a 4.7 kΩ, 1%,
1/4 W end-of-line resistor for termination. If an output group is
not used, the 4.7 kΩ, 1%, 1/4 W end-of-line resistor must be
installed across the unused output group terminals.
For additional Class A wiring requirements, refer to your
control panel installation manual.
Observe polarity for all connections.
Configuration
Power source configuration
If power requirements exceed the maximum current the control
panel can provide, connect an external 24 VDC power supply
and remove jumper J3 (Figure 4).
Jumper J3 Power source
ON (default) 24 VDC is supplied by the control panel
OFF 24 VDC is supplied by an external power supply
Expansion board functionality
The expansion board functionality and event programming is
configured at the control panel interface. See your control
panel installation manual for further information.
Maintenance
Basic maintenance consists of a yearly inspection. Do not
modify the internal wiring or circuitry of the board.
Expansion board fault indications
Additional fault diagnostics are indicated by the ON and OUT1,
OUT2, OUT3, and OUT4 LEDs on the expansion board, as
shown below.
