INSTALLATION CONSIDERATIONS
SYSTEM REQUIREMENTS
1 Local “always on” Internet access such as a cable broadband or DSL service to the iCOMM™
system’s CM (communication module) - see page 6.
• Local Internet service must be provided to the CM’s LAN PORT via a field supplied Category 5
network cable with a RJ45 male plug end - see Figure 2 on page 6. This cable is not included with
the iCOMM™ system hardware.
• Local Internet service must use DHCP servers/routers and assign an IP address to the CM
automatically.
• Local Internet service must allow access to the iCOMM™ web site at:
www.stateconnect.com
Network security/firewalls must not prevent the CM from accessing this web site.
2 Available 120 VAC outlet(s). A field supplied 120 VAC power strip or outlet multiplier may be
necessary to provide power for the iCOMM™ components. Field supplied extension cords may
also be necessary to bring power to the iCOMM™ components.
• One available socket at a 120 VAC wall outlet for the iCOMM™ system’s CM for all installations.
• If the optional Alarm Box (page 21) is being installed a second 120 VAC socket will be needed.
• Field supplied wireless network adapters may also require a 120 VAC socket for power.
3 Multiple Device Adapters - MDAs
• MDAs (multiple device adapter - see page 16) are required for each “tank type” water heater on all
Multiple Appliance Networks - networks with more than one water heating appliance connected.
MDAs are an accessory component that is ordered separately. Determine how many “tank type”
water heaters will be connected on all Multiple Appliance Networks. Order one MDA for each tank
type water heater before the installation begins - see Figure 1.
