BHS-4000A Installation and Programming Instructions
3.2 W ire the zones
3.2.1 W iring the burglary zones
Burglary zones circuits can have a normally-open, normally-
closed, or an end-of-line (EOL) configuration. For UL applications,
however, an end-of-line configuration is required. When
configuring an EOL circuit, use a minimum 22 AWG wire and a
maximum wire length less than 1000 feet.
Wire the zone’s detection device(s) according to the
manufacturer’s instructions. Connect the sensor between the
appropriate Z terminal on the panel and the adjacent common
terminal.
3.2.2 W iring the fire zone
The BHS-4000A panel is designed for four-wire smoke/heat
detectors only. Fire zones always require the EOL configuration.
Wire the smoke/heat detector as outlined below:
1. Connect the positive power loop wire to the FIRE
terminal.
2. Connect the negative power loop wire to one of the
common terminals.
3. Connect the detection loop to the zone and common
terminals on the panel. Make sure the zone is
configured as a fire zone.
4. When using the System Sensor Model 2112ATL Smoke
Detector, connect the Sync terminal to the Siren output.

Note: Connect the keypad using a minimum 22 AWG wire and a
maximum wire length of 650 feet.
3.3.2 W iring multiple keypads
The BHS-4000A can support up to 16 keypads, but they can have
ID numbers that range from 1 -128. These keypads can be
connected in daisy-chain (parallel), individually home-run, or
wired using a combination of these two methods. A combination
of LED and icon keypads can be used in the same installation.
3.4 W ire the digital communicator
The digital communicator is integrated into the BHS-4000A
control panel. To connect the panel to the house phone, do the
following:
1. Locate the 8-conductor cable, attached to the right-hand side
of the BHS-4000A’s main PCB.
2. Insert the cable’s plug into an RJ31X or an RJ38X jack.
3. Wire the RJ31X jack as shown:

Note
The colors of house phone wires vary. If the wire colors do not
match the diagram above, connect the yellow wire to the wire
that was connected to terminal 4, and connect the black wire to
the wire that was connected to terminal 5.
3.5 Wire the ZEM
3.5.1 Connect the wires to the terminals
Wire the ZEM, following the instructions below:
1. Disconnect the system’s AC and DC power.
2. Wire the ZEM according to the table and illustration.

3. W i r e the zone inputs in the same manner used to connect
devices to the panel’s eight on-board inputs.
* If the ZEM is mounted more than 10 feet from the control
panel, a separate earth ground connection is recommended.
Refer to Section 3.11.2 for additional information on
connecting to earth ground.
3.5.2 D aisy chaining
To simplify the system’s wiring, devices can be daisy-chained
together. Use each device’s V+, V-, CLK, and Data terminals for
making daisy chain connections.
Daisy chaining is not recommended and extreme care should be
taken when using this wiring method. If daisy chaining is used, a
broken wire or loose connection in one device affects all
additional devices in the chain.
