HA40 4-Channel Controller

•Over Ride menu allows entering one of the 16 different alarms that will trip this relay regardless of the Votes entries. There are four alarms per channel and four channels and any one of these alarms may be used as the Over Ride. This feature is useful when one channel’s alarm has more significance than the others.

•Horn controls how activating this relay will affect the horn driver circuit connected to J2 on the motherboard. Choices are NO, STEADY or PULSE. Warning level alarms might be set to pulse the horn and high alarms set for steady. Personnel can then know which alarm level is present by hearing the pulsing or steady horn.

•Turning Acknowledge ON (not allowed on Relay 1) allows Relay 2 to be deactivated during alarm conditions by an Alarm Reset. This is useful if another audible device is being driven by the relay. The acknowledge feature is not available for Relay 1 since it is often used for driving a warning light and Relay 2 for driving a horn. It could be dangerous if an operator acknowledged the horn AND the light since no indication of the high alarm condition would remain.

2.3.2 Clock / Delays Menu

The HA40 monitors signals from inputs that may require varying times to stabilize after power is applied and after calibrations are complete.

•Alarm Refresh menu allows reactivation of Acknowledged alarms after the time period expires. This feature is used primarily to restart audible alarm devices after having been silenced by an acknowledge function (via serial port or pressing the Alarm Reset button). An entry of 0 seconds effectively disables the Alarm Refresh function.

•Warm-Up Delay menu allows setting how long alarm relays remain disabled after power is applied.

•Cal Delay determines how long alarm relays are inhibited after completing a calibration.

•Time and Date menu items are for setting the correct time and date. The HA40 is equipped with a 24-hour clock and calendar. Time of day must be entered in 24 hour mode. For example, 6:00:00 PM = is indicated as18:00:00.

2.3.3 COMM Port Remote ID Menu

The system Remote ID menu allows setting RTU address for the optional slave Modbus serial port (requires 10-0253 Modbus option PCB – see Section 3.2). This slave port may be used to transfer HA40 data to a host device such as a PC, PLC, DCS or even other Honeywell Analytics controllers, such as the 16 Channel HA71. The slave port is addressable, allowing many HA40 controllers to be connected to a single RS-485 cable. A converter is available to make this port also compatible with Ethernet TCP/IP networks.

HA40 specifications

The Honeywell HA40 is an advanced air quality monitor that offers a multitude of features designed to provide users with accurate and real-time data regarding their indoor air conditions. As part of Honeywell’s commitment to improving the environments where people live and work, the HA40 stands out as an essential tool for continuous air quality assessment.

One of the main features of the Honeywell HA40 is its capability to measure a variety of air pollutants. It provides real-time readings of particulate matter (PM2.5 and PM10), volatile organic compounds (VOCs), carbon dioxide (CO2), and formaldehyde levels. This comprehensive monitoring allows users to understand their air quality better and take appropriate actions to improve it.

The HA40 is equipped with advanced sensor technology that enhances its accuracy and reliability. The device utilizes laser scattering methods to precisely detect particulate matter, which offers detailed information on the concentration of airborne particles. Additionally, its integrated VOC sensor leverages photoionization to deliver quick and exact results concerning the presence of harmful compounds in the air.

Another notable characteristic of the Honeywell HA40 is its user-friendly design. The device features a clear, intuitive display that presents data in an easily understandable format. Users can quickly assess air quality levels at a glance and receive alerts when pollutants exceed predefined thresholds. Furthermore, the HA40 is compact and portable, making it suitable for both home and office use.

Connectivity is another strong point of the Honeywell HA40. The device can be connected to a smartphone application, enabling users to monitor air quality remotely. This app provides additional functionalities such as trend analysis, historical data tracking, and personalized recommendations for improving indoor air quality.

Power efficiency is also a priority with the HA40, featuring a low-power design that extends battery life and reduces the frequency of recharging. This makes it convenient for users who wish to place the monitor in various locations without the hassle of constant maintenance.

In summary, the Honeywell HA40 represents a significant advancement in indoor air quality monitoring. With its accurate sensors, user-friendly interface, and connectivity options, it empowers users to maintain a healthier living and working environment.
