Smoke Detectors

Compared to 2-Wire smoke detectors, a 4-Wire smoke detector uses an internal alarm relay contact and internal resistor. There is less restriction on the wiring of a 4-Wire smoke detector. 2-Wire and 4-Wire smoke detectors are very similar in job duties but mainly differ in how they connect. Customers may prefer a 4-Wire smoke detector because it is feasible to pinpoint the location of a triggered alarmed detector which is very useful in false alarm emergency situations

2-wire smoke detectors are hardwired smoke detectors that detect the early signs of smoke or fire using the zone wiring of the home or business fire alarm system. These devices are usually restricted to a hardwired zone and uses a single pair of wires to combine detection and power loops. In other words, the wires can carry signals when smoke is detected as well as power the detector, which reduces and accelerates installation time. If the alarm is cleared, the device is automatically programmed to reset the zone. At JMAC, we carry a wide selection of 2-wire smoke detectors by System Sensor, UTC Interlogix and more.

Browse through our selection of smoke detection devices for fire alarm systems. These devices are ideal for detecting the early warning signs of fire, heat or life-threatening emergencies in a building. Smoke detectors are usually linked to a centralized fire control panel and monitored. If an alarm goes off, signals to the alarm control panels are sent to alert fire officials or monitoring services. Photoelectric, dual sensors, and ionization are the most common smoke detectors you'll most likely find in commercial and residential buildings. At JMAC Supply, we provide a wide range of smoke detectors with unique features and power sources.

Addressable Smoke Detectors

Find the source of problems faster, while simultaneously protecting occupants and property with our massive selection of addressable smoke detectors. Most smoke detector systems are equipped with their own fire alarm control panel making it difficult to locate which area of an establishment triggered the alarm, especially if multiple alarms are used in large buildings or areas. In this situation, addressable smoke detectors, also known as analogue smoke detectors are the best type of detectors to use and are perfect for large commercial buildings. The control panel of each addressable device is separated so it can be controlled by a central fire alarm panel. The setup of an addressable fire alarm system allows it to quickly identify which smoke detector device was individually activated. This means more issues can be detected, isolated and resolved faster and more efficiently than any other type of smoke detector on the market. The critical information provided by addressable alarm systems allows firefighters to pinpoint the exact location of an alarm signal, which is very useful in managing an emergency, especially in a large building.

JMAC delivers an extensive selection of durable and reliable addressable smoke detectors. We carry models from Silent Knight, FireLite, Honeywell, Notifier and more. You can also find other types of fire-safety addressable devices like addressable duct smoke detectors and addressable heat detectors that guarantee fire protection. Choose a reliable and high-performing addressable smoke detector that will offer long-lasting dependability. We offer wholesale pricing on all units, and all orders ship out the same day from our New York warehouses. Call us at 516-812-0917 to find the right smoke detector for your needs!

At JMAC Supply, your security is our top priority!

Because you will be able to respond faster to a fire or a problem within certain areas of an establishment instead of using the sound of the alarm to identify where it's located, you can lower the risk of losing a life and fire damage altogether with an addressable fire alarm system.

FAQs about Addressable Smoke Detectors & Systems

1. What is an addressable smoke detector?

An addressable smoke detector is part of an addressable fire alarm system that consists of a group of smoke detectors and devices linked to a central fire control panel. In an addressable fire alarm system, an activated smoke detector can quickly be isolated and found because each device has a unique address or number.

2. How do Addressable Systems work?

The addressable fire alarm control panel and devices exchange data at high speeds through an electronic circuit, nowadays a loop or ring-type circuit. Devices include smoke detectors, thermal detectors, manual call points, and sounders.

3. What is the difference between conventional and addressable fire alarm systems?

An addressable fire alarm system allows you to easily determine which alarm system device has been triggered, where a conventional system does not. However, both fire alarm systems link a series of devices to a central control panel.

4. What is a conventional smoke detector?

Smoke detectors in a conventional system will go off individually once it detects heat or smoke in an area. The circuits in a conventional fire alarm system use a separate wire for each device to connect to the fire system control panel. However, despite the use of separate wiring in the conventional systems, these devices are not recognized individually but as part of a zoned area.

5. What is an analog addressable fire alarm system?

The most notable difference between Conventional and Analogue addressable fire alarms is how the alarm signals communicate with the system control panel. Analogue addressable fire alarm systems act by receiving a signal which has been transmitted via a single cable running through all installed detection devices. Each wiring has a unique address or number to identify each addressable smoke detector and linked device quickly.

6. What is a Zone in a fire alarm system?

Zone in a fire alarm system is a certain section of a building. Zones are not determined by where the wires run for the alarm system. Firewalls and fire doors determine this and separate each Zone from other all other zones in a building.

7. How many smoke detectors can you have in one zone?

You can have as many as 12 smoke detectors in a zone and six compatible devices (such as a door closer, bell or light) according to the standards of NFPA 72.

8. What are the two types of fire alarm systems?

Conventional and addressable are the two types of fire alarm systems most commonly used within a commercial setting. While they share similarities, mainly the wired connection to a centralized system, they also have distinct features that should be taken into consideration while choosing the best system required for your business. Conventional systems are budget-friendly options for smaller buildings such as coffee shops or retail stores as the upfront cost is much less.

9. Addressable smoke detector vs conventional smoke detector. Which is better?

Conventional smoke detector systems cost less but take up more man-hours due to the amount of wiring work involved and are subject to more false alarms and signal mishaps, which can be tedious, boring, and costly to resolve.

Addressable smoke detectors price or budget is usually higher but minimizes labor cost with less wiring and easier installation while ensuring uninterrupted business operations or unnecessary fire procedures with less false alarms, and failsafe wire mechanisms. Also, the critical information provided by addressable alarm systems allows firefighters to pinpoint the exact location of an alarm signal, which is essential for large commercial buildings.

10. How many types of fire alarm panels are there?

As of 2019, the two types of fire alarm panels are conventional alarm panels and analogue or addressable fire alarm panels.

11. Which is better ionization or photoelectric smoke detector?

A photoelectric smoke detector responds better to slow, smoldering fires such as a smoldering mattress, whereas ionization fire alarms respond better to rapid flaming fires.

12. Do you have an example of an addressable smoke detector wiring diagram?

13. Do circuits in fire alarms sense smoke or fire?

No, fire alarms normally come with a thermistor sensing circuit but that does not mean it can sense smoke or fire. A thermistor sensing circuit features a thermal sensor that senses heat to detect fire or smoke.
