Instructions for installing fire detection and fire alarm on Dahua Camera DHI-HY-FT431LDP – Dual image

Dahua fire detection and fire alarm camera DHI-HY-FT431LDP is a completely new product from Dahua with the ability to detect fire thanks to the Uncooled VOx thermal sensor (heat detection) with high sensitivity and early warning. The DHI-HY-FT431LDP code will have 2 thermal image streams and is usually different from the DHI-HY-FT121LDP code which only has 1 regular image stream. In today’s article, I will guide you in detail!

Dahua Fire Detection Camera and DHI-HY-FT431LDP Fire Alarm supports smart features such as:

• Abnormal heat point alarm
• Fire alarm
• Abnormal temperature alarm

You log in to Camera --> Event

1. Abnormal heat point alarm

Go to Cold Hot Spot --> Check Enalbe then set the following reference parameters:

• Temperature Unit: The temperature unit you can choose Centigrade (degrees Celsius) or Fahrenheit degree (degrees Fahrenheit)
• Hot Spot Color: Hot access point color – you can choose 1 color at your discretion
• Cold Spot Color: Cold access color – you can choose 1 color of your choice
• Alarm Condition: Single (arbitrary low and high temperature setting modes) – Combination (high and low temperature setting modes combined)
• MaxTempThreshold: the high temperature allowed, here I set 100 degrees, if it exceeds 100 degrees orange, it will alarm
• MinTempThreshold: the temperature level is low allowed, here I set 0 degrees, if I exceed 0 degrees orange will alarm
• Anti-dither: anti-shake to default level 3 or depending on usage needs
• Schedule: set the operating time of the alarm feature
• Event Linkage: Event link, settings for you to configure alarm sending or if you install a separate siren speaker
• Record: you can leave the default by camera
• Alarm out port: you can leave the default by camera
• Then click Apply to save the configuration

2. Fire alarm

Go to Flame Alarm --> Check Enalbe then set the following reference parameters:

In item number 3, you can select the entire alarm fire detection area or non-alarm exclusion zone.

• Duration: 3 (Break between 2 alarms)
• Repeat Alarm Time: 20
• Sensitivity: 7 (Fire detection sensitivity)
• Schedule: Full Time (Or you can set it according to the time you want in the Add Schedule section)
• Event Linkage: Event link, settings for you to configure alarm sending or if you install a separate siren speaker
• Audio Linkage: Enable
• Play Count: 3 (Number of times alarm sounds)
• File: You can select the alarm sound file when fire is detected
• Then click Apply to save the configuration

3. Abnormal temperature alarm

Go to Temperature Measurement --> Add Rule, in the abnormal temperature alarm feature will support 3 types of temperature measurement to alarm: Line (measure temperature on the drawing line), Spot (measure temperature on points), Polygon (measure temperature in the area you draw), each style will support up to 3 Rules

   

A. Measure the temperature on the line drawn

Measure temperature on the drawing line, support up to 3 lines, 3 points or 3 zones, in the Type section you select modes such as Line --> Redraw Rule to draw lines at the location to measure temperature --> Set the reference temperature parameters as follows:

• Alarm results: alarm results, you can choose the appropriate modes according to your needs, here I choose Average Temperature (average temperature)
• Alarm Condition: alarm status, you can choose Below (the temperature below will alarm), Match (suitable temperature), Above (the temperature above will alarm)
• Alarm threshold temperature: alarm threshold temperature, here I set 20 degrees, if it exceeds below 20 degrees orange, it will alarm
• Temperature Error: permissible temperature error
• Temperature Duration: temperature maintenance time, meaning that the temperature is setting the threshold of 20 degrees alarm, then the temperature reaches above 20 degrees in a certain period of time, you will alarm
• Warning threshold temperature
• Warning temperature duration: temperature alarm interval
• Then click Apply to save the configuration

B. Point temperature measurement

C. Temperature measurement by zone

D. Set alarm parameters as previous features
