WARNING
This equipment generates, uses, and can radiate radio
frequency energy, and if not installed and used in accordance
with the instructions manual, may cause interference to radio
communications. It has been tested and found to comply with
the limits for a Class A computing device pursuant to Subpart
J of Part 15 of FCC Rules, which are designed to provide
reasonable protection against such interference when
operated in a commercial environment. Operation of this
equipment in a residential area is likely to cause interference,
in which case the user, at his own expense, will be required to
take whatever measures may be required to correct the
interference. Any unauthorized modification of this equipment
may result in the revocation of the owner’s authority to
continue its operation.

Mount controller subpanel in cabinet so all labeling is visible.
Secure full-size subpanel in place with six no. 10 x ½-inch
(13 mm) sheet metal screws (not supplied). Secure smaller

General
The XL800 Series is designed to provide heating, ventilating
and air-conditioning control. They can operate either
standalone, or networked to Honeywell central workstations
such as EBI. These controllers can also be used for smoke
control system monitoring and control, for monitor and control
of fire (UL864), and general purpose signaling (UL2017). In
UL 2017 applications, the product can be used as a type NM
(Non-Monitored) system. It is also approved for UL916
(Energy Management Equipment.)
The XL800 Series can be used for smoke control applications
when used in conjunction with a UL listed fire alarm control
panel (FACP) and UL listed fire fighters’ smoke control station
(FSCS).

24 VAC output (rated 2A) must be wired in accordance
with NFPA 70, Article 725 when routed within the
cabinet or adjacent cabinets and also for external field
wiring.

14507287-001, -002, -003, and -007 control power
module 24 VAC output is inherently power-limited.
Thus, all sourced power from the XL800 controller is
power-limited. All field wiring from these controllers
meet NFPA 70, Article 725 power limited Class II
requirements.

If a separate auxiliary power-limited 24 VAC power
source is required, use a control power module
(14507287-001 or -007 control supply).

Devices must be installed in areas as shown. All cable
must be routed as shown. All internal power-limited
wiring must be separated by ¼ inch (6 mm) or barrier
from non-power-limited wire. Excess wiring must be
cut, trimmed, and dressed properly to ensure that
proper clearances are maintained.

Data File Set-Up
Generate the engineering data file for the XL800 Series
Controllers. This data file has a mix of hardware points for the
necessary inputs and outputs to control fans, dampers, and
other equipment. In addition to the inputs and outputs, a
custom control program is written to control the outputs per
the sequence. The XL800 controllers can reset the program
once the data from the operator interface indicates a normal
condition for the dedicated smoke control equipment. Wire

Setting Address of Panel Bus I/O Modules

► Use the rotary HEX switch to set the address to the one

already defined during engineering.

Each Panel Bus I/O module is assigned its own unique
address. For the sake of clarity for maintenance personnel, it
is recommended that you address the Panel Bus I/O modules
in ascending order 0 through F.

LOCK

The LONWORKS Bus is a 78-kilobit serial link that uses
transformer isolation so that the bus wiring does not have a
polarity. I.e. it is not important which of the two LONWORKS
Bus terminals are connected to each wire of the twisted pair.
The LONWORKS Bus does not need to be shielded on the
controller module side.
The LONWORKS Bus can be wired in daisy chain, star, loop or
any combination thereof as long as the maximum wire length
requirements are met.
Configuration

Fig. 14. HEX switch location

NOTE:

If the HEX switch setting is changed, the Panel
Bus I/O module will revert to its default
configuration. With LONWORKS Bus I/O modules,
the HEX switch is without function.

Setting the I/O Bus Switch
► Set the I/O Bus switch S2 of the XCL8010AU Controller

Module depending on the modules connected to terminals
71 ─ 78 and the desired communication as follows:

The recommended configuration is a daisy chain with two bus
terminations. This layout allows for max. LONWORKS Bus
lengths, and its simple structure presents the least number of
possible problems, particularly when adding on to an existing
bus.

C-Bus Topologies
Via the C-Bus up to 30 C-Bus devices (e.g., controllers, etc.)
can communicate with one another and a PC central. The CBus must be connected via the individual controllers (open
ring).

Description of the I/O Modules

Modules with Manual Overrides
The XFR822AU/XFLR822AU Analog Output Modules are
equipped with manual overrides: one rotary knob for each
analog output.
The manual overrides can be set manually to either "auto" or
"0 ─ 110%".

This updating (synchronization) is performed:
• If the calculated position of the actuator
< lower synchronization threshold (2 %)
= synchronization towards 0 %
• If the calculated position of the actuator
> upper synchronization threshold (98 %)
= synchronization towards 100 %
• Following any power-up or any reset

NOTICE
Damage to the electronic module!
► Do not use a tool to adjust the rotary knobs.
► Do not use excessive force. Adjust only by hand.

Synchronization Behavior of Analog Output Module
Configured as Floating Output
In order to regularly update the real actuator position with the
calculated position and thus ensure that the actuator
definitely reaches its end position, a synchronization process
is performed by the Analog Output Module.
During the synchronization process, the Analog Output
Module will continue running for the configured runtime once
it reaches the calculated end position.
