1. Preparing to install the RelyanceHub™
The RelyanceHub is designed to monitor ambient temperature and humidity, and has
eight input ports to detect Normally Open or Normally Closed contact closures from
various optional devices. The RelyanceHub provides current limited (12mA), optically
isolated inputs to sense contact closures provided by smoke detectors, magnetic door
switches, flood detectors, etc. +12 Vdc with over current protection is provided on pins
1- and 4+ of ports 3, 4, 5 and 6 to power sensors that require it.
Prior to installing the RelyanceHub, the optional sensors and associated wiring should
be installed and the wires labeled. Installers must follow instructions provided by the
sensor manufacturers and applicable codes when installing sensors.
Locating The RelyanceHub
The RelyanceHub can be recessed in a wall using a standard 3-gang plastic electrical
box or on the surface of a wall using the mounting box supplied. The RelyanceHub
should not be mounted in a metallic box. This will limit the range of the Wi-Fi and
Bluetooth transceivers. All of the wiring and sensors should be installed prior to
installing the RelyanceHub.
The RelyanceHub should be mounted in a location that will not be subjected to rapid
temperature swings such as near an outside door, HVAC duct or in direct sunlight. This
will allow for more consistent data from the internal temperature and humidity sensors.
The RelyanceHub should be mounted vertically mid-level on a wall at approximately the
same level as a light switch would be mounted and in compliance with local codes.
If the RelyanceHub is to be connected to the internet using Wi-Fi, be sure that the hub
is located within the coverage area of the desired Wireless Access Point(s).
Powering The RelyanceHub
The RelyanceHub can be powered by 24 V, AC or DC. This is done using one of two
methods.
Method 1 is to use a standard HVAC type AC transformer such as the Honeywell AT-
120A 20VA transformer. The transformer is connected directly to the electrical mains per
local code and the instructions provided with the transformer. Connecting the
RelyanceHub using this method prevents accidental or intentional disconnection by the
tenant.
