System Sensor 4WT-B Frequently Asked Questions

How Does a Fire Detector Work?
There are two primary methods for detecting a fire. These are through either smoke detection and heat detection. For that reason, a "fire detector" is more commonly referred to as a "smoke detector" or a "heat detector". There are also combo smoke and heat sensors. Learn more about these devices.

How Do I Wire a 4-Wire Smoke Detector to My Wired Alarm System?
Connecting a 4-wire smoke detector to a wired alarm system is a slightly more complicated process than setting up most other hardwired zones. Several wired connections will need to be made. The setup will also require an end of line resistor and a relay module. Learn more about 4-wire smokes.

How Do I Add a 4-Wire Smoke Detector to My Wireless Alarm System?
In order to use a 4-wire smoke detector with a wireless alarm system, a special type of wireless transmitter is needed. The transmitter must be capable of supporting normally open life-safety devices with an end of line resistor. Learn more about using a 4-wire smoke with a wireless system.

Will a Smoke Detector Detect Heat?
Not all smoke detectors are designed to detect the presence of high heat. These sensors will only detect high heat if that is a specific function of the device. Otherwise, a smoke detector will only detect smoke, and nothing more. Learn more about smoke detectors and their functionality.
