Installation Instructions

- 4 - LINQ8PD/LINQ8PDCB
Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all local codes and authorities having jurisdiction.
Product is intended for indoor use only and should be installed by qualified personnel.
1. Disconnect the AC mains and batteries (if used) from the power supply(ies) before connecting the LINQ8PD(CB)
2. Mount LINQ8PD(CB) into position and secure with mounting screws.
Interconnecting two (2) LINQ8PD(CB) modules: Two (2) LINQ8PD(CB)s can be interconnected to enable both units to be accessed from a single IP address.
Connect interface cable (supplied) to the interface port marked [DOWNLINK] of first LINQ8PD(CB) which will be the master to interface port
marked [UPLINK] of second LINQ8PD(CB).
3. Power Supply Input Connection: The LINQ8PD(CB) can be connected to two independent AC or DC power supplies that can be routed thru each of the individual outputs.
Each output is equipped with an input selection switch which is used to route the desired input to the output. This switch also has a center off position that can be
used to turn power off to an output.
(a) Single Power Supply Input: Connect the output of the power supply to the terminals marked [+INP1-] and set the Input selection switch for
each output to the [INP1] position.
(b) Dual Power Supply Inputs: When the use of two independent power supplies is desired connect one power supply to the terminals marked [+INP1-] and the
second power supply to the terminals marked [+INP2-]. Set the Input selection switch for each output to the appropriate position. Reconnect the AC mains of
the connected power supply(ies) and verify the voltage of each of the eight outputs. This helps avoid potential damage. Disconnect the AC mains of the
connected power supply(ies).
Note: Do not connect AC and DC simultaneously to INP1 and INP2.
4. Output Connections: Connect devices to be powered to the terminals marked [-OUT1+ to -OUT8+] on LINQ8PD(CB) carefully observing polarity. When two
power supplies are connected to the LINQ8PD(CB) verify that the output voltage matches the operating voltage of the connected devices.
5. Battery Connections: Skip this step when connecting AC power supplies or DC power supply(ies) without batteries.
Connect the power supplies battery charging circuit to the terminals marked [+BAT IN-], connect the battery leads to the terminals marked [+BAT OUT-].
Note: Do not connect battery(ies) until all connections have been made.
For 24VDC operation connect two 12VDC batteries in series using the supplied yellow battery jumper. For Access Control applications batteries are optional. When batteries
are not used, a loss of AC will result in the loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
6. Battery and AC Supervision Connections: Skip this step when connecting AC power supplies
These connections are required to monitor AC and Battery Trouble conditions. These conditions cannot be monitored when connected to a non-supervised power supply.
Connect the common (C) and normally open (N.O.) contact of the power supplies AC and Battery supervision relay to the corresponding DRY Inputs of the LINQ8PD(CB).
If required to connect supervisory trouble reporting devices to outputs marked [AC FAIL, BAT FAIL] supervisory relay outputs marked [NC and C]
to appropriate notification devices. Use 22 AWG to 18 AWG for supervision reporting.
7. Fire Alarm Interface options: (not evaluated by UL)
The Fire Alarm Interface and Reset options are programmable via the web interface. FAI input trigger options: supervised normally closed [NC], normally open [NO],
polarity reversal input from signaling circuit or wet input will trigger selected outputs.
(a) Normally Open [NO] input: Connect the supplied 2.2k resistor (supplied) in parallel with the normally open trigger circuit to the terminals marked [GND, FACP EOL].
(b) Normally Closed [NC] input: Connect the supplied 2.2k resistor (supplied) in series with the normally closed trigger circuit to the terminals marked [GND, FACP EOL].
(c) Signaling Circuit/Wet input trigger: Connect the positive (+) and negative (-) of the signaling circuit/wet input trigger to the terminals
marked [FACP IN + and [FACP IN -].
(d) Fire Alarm Reset: If a output is programmed to latch with manual reset connect either a normally open (N.O.) or normally closed (N.C.) dry input to the
terminals marked [RESET & GND].
8. Reconnect AC power mains to the connected power supply(ies) and connect back-up batteries.
