Why we use the end of line resistor in fire alarm system?

  Kidde EOL-15 End of Line Resistor 15K Ohm The function of an end of line (EOL) resistor is to monitor the integrity of the circuit in a fire alarm system. This is achieved by placing the resistor at the end of the wiring loop, completing the electrical circuit. The control panel of the fire alarm system continuously monitors the resistance of the circuit, which should match the resistance value of the EOL resistor. Any changes from readings may indicate a potential issue, prompting the system to signal a trouble condition. An EOL resistor should always be installed as the last device in the loop and never inside the control panel. Placing resistors anywhere other than the end of the line does not serve a purpose. Open Circuit Detection When there is a break in the wiring or a device is disconnected, it creates an open circuit. This means that the electrical current cannot complete its path through the circuit, resulting in an increase in resistance. The EOL resistor, placed

Fire Detection and Alarm System

Image
I have a presentation to electronics engineering students in Iligan Institute of Technology – Mindanao State University, the title “ Fire Detection and Alarm System” or FDAS. Safety is a common word we hear in industries but some of the world seems to ignore this and the obvious reason was that the city enforcement of laws are weak. The goal was to spread the awareness on RA9292, the electronics engineering law inclusion to the National Building Code which is crucial to protect building occupants from harm and prevent damage to property. There are 3 important phases of fire detection and alarm system; the time element, notification (manual and automatic alarm) and activation. The idea of FDAS was to sense signs of fire and alert personnel to prevent fire from getting bigger. Why do we need FDAS when we already have some fire extinguisher?  To answer that question lets discuss the fire department response time. First the ignition where combustion starts and fire grows undetected

Where are you going from here?

  Career Talk March 2 2017, MSU-IIT ECE Week (March 2-5) My good advice to students who wants to go somewhere else, other than the Philippines. Which direction are you going to take after college, or after you become an engineer or a technician? Most people will tell you to go overseas because the truth is there is no opportunity here. But what about your own family, friends that you care, favourite pets and the many places you enjoyed having fun for so many years. Are you just going to leave the place, for what – the money? Of course that is what most of us is up to and that is what we keep on focusing on – money. When we graduate, we accomplish one important goal that is to finish a degree on electronics engineering. There are lots of your seniors who took two licensure exam, one for electronics technician (ECT) and the other for electronics engineer (ECE). Well that’s fine and another good achievement of you if you make it. I urge everyone of you to keep on learning and sharing,

Technnovation 2016

I was invited to be a judge for three students projects namely; a Solar-powered Hybrid Vending Machine, Smart Switch, and an Improved Mechanized Ice Cream mixer done by graduating electrical engineering students who participate on Iligan Institute of Technology, Mindanao State University – Innovation Convergence last August 30-31, 2016. The title of the event was 2016 Technnovation with the theme, “Advancing Technopreneurship and Innovation in Mindanao”. In parallel with other session they have these: Cluster 1 Resilient Structures, Disaster Risk Reduction and Management and Environment Cluster 2 Energy and Power Cluster 3 Health, and Pharmaceuticals Cluster 4 Food and Nutrition Cluster 5 Instrumentation and Control I am at Cluster 5 to judge the three projects, this is last August 31, 2016. The first one the Solar-powered Hybrid Vending Machine was very crude but I could understand that the students has to balance their budget with the idea of having an economically and portable v

Breaking the Bad Structured Cabling Habit

I had a technical talk in Iligan Institute of Technology, Mindanao State University last September 22 2016. This was in a gymnasium, the organiser choose that place to accommodate both the professionals, visitors and the students on its 1st JIECEP-IBC Summit 2016. The seminar, “ Implementing a Structured Cabling System ”, is based on ISO/IEC 11801. My plan was to discuss the important issues ignored during the implementation. I have intentionally selected few sections to fit the allotted time.  A Structured Cabling System (SCS) is a method for creating an organized cabling system that can be easily understood by installers, network administrators, and any other technicians that deal with cables. This method works best when you follow the standards. Industralized nations have the standards. Specialist / Engineers who made these standards have extensive experience over this technology. Every 5 to 10 years these standards are reviewed and change when necessary to fit in the

The Endless Gift of Sharing

Computer Hardware Module I still remember the time when I was a kid, I would receive frequent scolding from my mom for not studying good to earn good grades. It took me a very long time to realize how important education towards meeting challenges in life is. As part of our childhood, I think most of us do not remember the complexities involved with learning something in school. Many children are struggling on how to read, and they prefer to play instead. This is what makes the equation more interesting to me, allow them to play around and subconsciously they will learn something. I never thought that if I share my skills, I will be losing money or I will get broke but it didn’t. My experience in giving my time, energy, resources, and leadership to create a positive impact in my community is awesome. I could not explain the feeling having to train people to learn electronics, computers, or self-development and hearing their own stories how they used that skills into their own live
