Power Interface for Access Control, CCTV, Fire, and general low voltage system control
Features:
• 8 Heavy duty Relays with individual Inputs and Status LED’s
• Each Relay Input can be Activated from Low Current Open Collector, Normally
Closed or Normally Open Switch
• EOL End of Line Resistor Fire Interface Master Trigger de-energizes all Output
Relays that are Enabled
• Universal 12 – 28VDC power input(Nominal 12-24VDC)
• 8C8R is Class 2 Power Limited
• Class 1 wiring required for 8F8R unless powered by a UL 294 or 603 or ULC
S318 or ULC S533 listed power supply with class 2 output. There shall be a
min of ¼ separation between power limited and non-power-limited circuits.
• Available with Fuses or PTC Circuit Breakers
Each Output may be Individually Configured for:
o Fire Trigger (FT) Enabled or (FTD) Disabled
o N/O or N/C Option Configures the Relay Switched Output
• Each Output 1-8 has a protected, continuous Output and a Relay controlled Output
• Control Power and Main Lock Power may be Isolated (Separate Power Supplies) at Users Option
Note: Dual/separate power source configuration has not been evaluated by UL and cannot be configured for UL Listed products
Description / Instructions
The PDB-8F8R is a versatile, compact way to distribute and control
power for Access Control Systems with Fire Alarm Interface. The
PDB-8F8R is an 8 position power distribution board with individual
Relays with input (IN) control for each output (OUT). An EOL
resistor trigger input (TRIG), will force all output relays to de-
energize that are selected (FT). In a typical installation, the TRIG
would be connected to a Fire Alarm panel via a set of contacts.
When the Fire Alarm trips, all enabled relays would be forced to be
de-energized to unlock electric doors, shut down air systems, and
or return elevators to ground floor.
Input / Output Terminals, Jumpers and LED
Details and Specifications
Control Power (- CONTR +) Two position un-pluggable terminal
block is used to power the coils of the relays. The control voltage
must be between 12 and 28 VDC. Each relay energized will draw
20ma of current. By default, Control Power and Main Power are
connected together with jumpers J1 & J2 so no connection would
be made here unless you were using Dual/separate power as
described below. Note Dual/separate power source configuration
has not been evaluated by UL and cannot be configured for UL
Listed products.
Main Power (- POWER +) Two position un-pluggable terminal
block provides the power to the outputs to be distributed and
power to Control through J1 & J2. In a normal application, the
Power must be between 12-28VDC and would be connected here.
Dual/Separate Power J1 & J2 Jumpers Note Dual/separate power
source configuration has not been evaluated by UL and cannot be
configured for UL Listed products. J1 Connects (-) Power to (-)
Control, J2 Connects (+) Power to (+) Control. By default J1 & J2 are
connected together. When J1 & J2 are cut, you must supply 12 to
24VDC to Control power See Dual/Separate Power application
figure below.
Inputs (1-8 IN C) Eight, two position un-pluggable terminal blocks.
When IN & C are shorted together, the like number output relay will
energize. Each relay can also be energized by an open collector that
is common to the control power, sinking 20ma for each input. Each
of the C’s (common) are connected to control negative power.
Input LED’s (1-8) Whenever an input is active (relay energized) the
associated input red LED will illuminate.
FDT/FT (1-8) Jumpers - These are three pin headers adjacent to
each fuse with a shunt with handle that shorts the center pin to
FTD or FT.
FTD = Fire Trigger Disabled - When selected, the Trigger will
not effect that output.
