LV-8RS
Low Voltage Power Distribution Module
The LV-8RS distributes power from a low voltage power source to 8 fused outputs
through 8 Output Isolation Relay sockets -or- can be congured to provide up to 8 dry
contact relay outputs. Terminals are provided for control of each output relay by an
Access Control system. Output devices can be powered separately from the control
relays by conguring Common Power Jumpers. A 2-pole Disconnect Relay socket
is provided and easily interfaces with Fire, Life Safety or Alarm Panels to provide
Emergency Power Disconnect. Relay auxilary contact terminals are provided for alarm
monitoring of the Disconnect feature.
Each of the 8 outputs includes a removable jumper clip easily congurable for one
of 3 modes of operation:
1) D position - Disconnect or Fail Safe operation of the output.
This means the output is disconnected by the Disconnect Function.
2) C position - Continuous or Fail Secure operation of the output.
This means the output is unaffected by the Disconnect Function.
3) DRY position - A jumper in this position congures the output for dry relay
contacts. Since an output in this mode is not powered, the jumper blocks the
installation of a fuse in the corresponding output fuseholder.
The LV-8RS includes red LED indicators at each of the 9 relay positions for identica-
tion of energized relays.
The module is 5.00” wide x 8.00” long. The installed height with relays is 2.50”.
Standoffs are included for mounting the circuit board in a user-supplied enclosure.
Relays and 3AG-type Fuses are provided separately. To meet UL Listing require-
ments, the relays selected should be Idec Corp., P/N RH1B-U SPDT or P/N RH2B-U,
DPDT, 12vdc or 24vdc.
* * * WARNING * * *
Turn off all power feeding the module terminals before servicing or changing input/output wiring, removing
or reinstalling fuses, relays, or jumpers. Failure to observe this warning may cause electrical shock hazard
or may damage internal or external circuit components.
The information in this manual is believed to be accurate in all respects. However, BASE Electronics cannot assume
responsibility for any consequences resulting from the use thereof. The information contained herein is
subject to change and BASE Electronics may issue a revision to incorporate such changes at any time.
INSTALLATION
Locate the unit inside a UL Listed NEMA 1 enclosure (such as a BASE LVPC Low
Voltage Power Cabinet) close to the source power supply. Drill (4) 0.187” diameter
holes to match the (4) corner holes in the printed circuit board. Push the nylon standoffs
supplied into each hole and snap the module into place.
Note: To comply with UL294 - Standard For Safety - Access Control System Units
and the limitations of the UL product Listing, the LV Module should be located within
the same room as the associated Access Control equipment and interconnect cabling
to the LV Module inputs. The unit is to be powered from a Class 2 Power-Limited
UL Listed Source.
POWER SUPPLY WIRING
Common Relay Control and Output Voltage If the output devices require a DC
operating voltage, the Common Power Jumpers can remain intact and only one DC
power supply needs to be connected to the PWR input terminals. In this mode, the
DC operating voltage of the control relays, output devices and the power supply must
match. Example: Output devices = 24VDC Maglocks, Power Supply = 24VDC, Relays
must also be 24VDC.
Separate Relay Control and Output Voltages
By cutting the Common Power Jumpers, two separate power supplies of like or different
voltages may be used to power the output devices and control relays. The relay power
supply must be DC. The output power supply can be either AC or DC.
Connect the power supply input leads to the terminal strip at the lower right side of
the module as shown in Figure 1. Use a minimum of 18AWG copper conductors for
this wiring and keep the length to the power supply as short as possible.
The values of the CTL and PWR voltages may be written on the white areas provided
in the lower right side of the module for easy future reference.
Output Relay Run Power Common
Power Supply Power Supply Supply Wiring To: Power Jumpers

OUTPUT MODE CONFIGURATION
Each module includes 8 jumper pins for conguring the mode of operation for each
of the 8 ouputs. They are installed in the C position from the factory.
C position - Continuous Power Mode The output is continuously powered and
unaffected by the Power Disconnect feature. If all 8 outputs will be congured in the
C position, there is no need to install a Disconnect Relay in the 2-pole socket.
D position - Disconnect Mode The output power will be disconnected by the Discon-
nect Relay when the Fire Panel Interface control circuit is opened.A 2-pole Disconnect
Relay must be installed in the socket provided.
DRY position - Dry Contact Mode The output becomes a dry Form C output. The
output is not powered or affected by the Power Disconnect feature. Since an output
in this mode is not powered, the jumper blocks the installation of a fuse in the cor-
responding output fuseholder.
POWER DISCONNECT WIRING
A socket is provided for a 2-pole relay that is used to disconnect the output power PWR
during facility emergencies. The relay is DC powered from the power feeding the CTL
terminals. Normally closed dry contacts of a re or life safety system panel are used to
control the disconnect relay at the ‘F’ terminals. The alarm contact should be rated for
the current required by the relay selected (normally less than 50mA at 12VDC).
The auxiliary output contacts of the Disconnect Relay can be monitored. Note that the
terminals designated NO and NC (shown in Figure 1) stand for Normally Open and
Normally Closed when the relay is de-energized. The terminal marked ST is a Spare
Terminal available for termination of an end-of-line resistor if needed.
OUTPUTS AND CONTROLS
Add the operating current ratings for each device to be powered from one output to
determine the expected operating current ow. Install a fuse for the output that will
trip when this value is exceeded. The value of the fuse selected for each output may
be written on the white area below the fuse for easy future reference.
Example A: Output 1 - (1) magnetic lock
operating current = 0.29A at 12 VDC
Install fuse rated just greater than 0.29A = 3/8A or 1/2A
Example B: Output 2 - (4) deadbolt locks
operating current = (4 x 0.40A) = 1.6A
Install fuse rated just greater than 1.6A = 2A
Wiring to output devices connects to the OUTPUTS terminals. Four terminals are
provided for each output as follows;
#C = output relay Common terminal when in DRY mode
spare terminal when in C or D modes.
NC = output relay Normally Closed terminal, powered when fuse is installed
in C or D modes, nonpowered and dry when in DRY mode.
NO = output relay Normally Open terminal, powered when fuse is installed
in C or D modes, nonpowered and dry when in DRY mode.
PC = output power PWR Common terminal in any mode.
Add the operating current ratings for each control relay and install a control fuse that
will trip when this value is exceeded. The value of the fuse selected may be written
on the white area below the fuse for easy future reference.
When powering devices over considerable distances, the cabling resistance may be
so high that the voltage available at the device drops to an unacceptable level. To
prevent this from occuring, the system cabling should be designed with adequate
sized conductors.
Suggested wiring methods for OUTPUTS and CONTROLS are shown in Figure 1.
All fuses must be type 3AG. Output Fuses must be 2.5A maximum or less. Control
Fuse must be 1.0A Maximum. Fuses are ordered separately - specify desired rating
when ordering.
LIGHTNING, TRANSIENT AND NOISE SUPRESSION
Lightning or transient suppression devices may be installed at the LV-8RS output
terminals to protect control equipment from induced voltages. A multi-screw, solid
ground bar should be installed vertically next to the output side of the module for con-
nection of metal oxide varistors, transient suppression diodes, etc. If shielded cable
is used for output wiring, shield drain wires can be connected to the ground bar for
line noise suppression. Run a minimum #14AWG green stranded ground wire from
the ground bar to the closest Service Ground. Grounding bars of the type mentioned
above can be separately supplied by BASE Electronics.
