NOTICE: This equipment has been tested and found to comply with the limits of a class B digital device, pursuant to
Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures. (1) Reorient or locate the receiving antenna. (2) Increase separation between the equipment and the receiver. (3) Connect the equipment into an
outlet on a circuit different from that to which the receiver is connected. (4) Consult the dealer or an experienced
radio/TV technician for help.
NOTICE: Operation is subject to the following two conditions: (1) This device may not cause interference, and
(2) This device must accept any interference, including interference that may cause undesired operation of the

EXI HALO Installation Manual Rev 2.0
1. INTRODUCTION
1.1. Intended Audience
This manual serves as a guide for Installers of the HALO system. The major components of the system
are described, as well as the system’s intended functionality, so as to gain familiarity with its operation
prior to installation. In order to successfully install and commission the system, it is absolutely critical
to understand the capabilities of the system and its components prior to installation.
The function of the HALO system is to monitor areas within a building for the presence of HALO
Tags. A Tag is sensed when it either enters an RF Field that is set up using the EXI HALO Controller
(referred to as a Tag in Field or TIF), or when the Tag initiates an alarm signal (referred to as Tag Initiated Communications, or TIC).
1.2. SYSTEM OPERATION
The EXI HALO system uses Radio Frequency waves for communications between the HALO system
components and the Tags. The HALO Controller continuously emits a 307 kHz RF frequency via the
Exciter Antenna, setting up a field in its local area. When a Tag enters this field, a Radio Receiver
within the Tag senses the 307 kHz RF field and transmits its identification information to the HALO
Controller using a low level Radio Signal at frequency of 434 MHz.

2. DECISIONS TO MAKE PRIOR TO INSTALLATION
2.1. SYSTEM WIRING
The HALO network is based on the RS-485 electrical interface standard, which is 2-wire multi-node
bus. The EXI HALO elements are designed such that many more than the RS-485 limit of 32 Drivers
and 32 Receivers can be co-exist on the same network. The baud rate used in the HALO system is
57,600 bps, and therefore in order to avoid data corruption it is important to ensure that a clean signal
is always present. Using the right type of cable, network topology, and not exceeding total cable length
are critical factors in ensuring that the system will operate reliably.
Figure 2 - "Bus" Topology Figure 3 - "Star Topology
Cable capacitance is a large factor in determining the quality of the signal on the network, and EXI recommends that cables with capacitance of greater than 15 pf per foot should be avoided. The network
should be constructed using a “multi-drop bus” type topology, avoiding any “star” type configuration.
The system is designed to operate with up to 4,000 ft of cable with the recommended topology and cable. The total cable length varies depending upon the cable capacitance and effective resistance, topology, and number of devices on the network. If the estimated total cable length is greater than 4,000 ft, a
RS-485 Repeater will be required to ensure that the system works reliably, or works at all.
It is also recommended that a Repeater be used to isolate HALO Elevator Controllers from the main
system to minimize noise pick-up and loading of the system. Cables used in Elevator shafts should be
stranded and not solid, and should be resilient enough to withstand the continuous flexing that it will
experience for many years in the elevator shaft.
