Product Overview

The HA72 controller is a flexible, scalable gas controller that works the way you need it to. Input/Output modules allow for sets of 16, 32, 48 or 64-channel monitoring. Deploy the HA72 as a robust standalone life safety solution or addressable network with gas monitors and other field devices. User-friendly and visually powerful, the HA72 interface puts you in control of mission-critical information and allows you to share it across the enterprise via a secure, password-protected interface.

Additional Features and Benefits:
Flexible & Feature Rich
Configure HA72 to accept inputs from many sensor types and signal ranges. Daisy chain up to 128 HA72 controllers to expand the system to meet your needs
Custom software auto-recognizes and addresses Honeywell gas monitors (XNX™ and Sensepoint XCD)
Connect sensors directly to HA72 with bridge sensor input board, saving installation time and eliminating need for extra devices 
Use HA72 as a discrete life safety system or network to a PLC or DCS for addressable operation
Multiple password levels allow Ethernet access according to user need or qualification
Various enclosure options available for hazardous and non-classified areas 
Programmable relays allow for a single relay contact point of multiple devices

Advanced, User-Friendly Interface
Full array of visual indicators (bar graphs, multicolor cells, flashing icons) and integrated alarm levels simplify and enhance monitoring, troubleshooting and trending functions
Improved zone logic reduces false alarm incidents 
Touch & magnetic keypad allows non-intrusive operation in hazardous locations
SD card logs over one year of data including concentration levels, alarm events, min/max, calibrations and alarm resets
NEMA 4X, NEMA 4X Stainless Steel, full and half “19” Rackmount and NEMA 7 (Explosion-Proof) wall-mount options
Modbus master/slave functionality allows for simultaneous sending and receiving of data, through four RS-485 serial ports
Calibration and Authorization Modes facilitate and speed commissioning time; Mimic Mode allows viewing of other HA72 controllers on the host display

Operate HA72 via the Web
An embedded web server provides HMI (Human Machine Interface)
and remote system configuration for the HA72. The Modbus TCP port
allows for remote configuration and viewing of the HA72 display via
your existing Ethernet. Multiple viewers can send/receive information
via the password-protected, secure interface. Know exactly what’s
happening with your gas monitors, at all times, from anywhere.
View, Access, Share and Store Your Data Easily
You can upload/download system configuration via SD card,
download the SD card onto additional HA72s for uniform
configuration and to cut commissioning time across your safety
system. The 2GB SD card also allows you to log over one year of gas
data, ideal for compliance and other safety reports and audits.
