What is Probe Type Heat Detector?

Probe Type Heat Detector General Specifications This can be used as a notifier device, to sense overheat or fire and alert personnel via the safety systems Fire Detection and control system, or can be used to sense a fire and actuate the release of extinguishing agent. These units are designed with rate compensation.

What are the two most common types of heat detectors?

There are two common types of heat detectors—fixed temperature and rate of rise. Both rely on the heat of a fire incident to activate the signal device.

How do you test a probe heat detector?


  1. Select appropriate heads for the diameter of detector probe shaft e.g. ½”.
  2. Slide the heads onto the shaft until they bottom out.
  3. Place Probe-Tester in a safe location.
  4. Position the two heated heads on the Probe-Test over the Heat Probe to be tested approximately 20mm from the end of the probe.

What is heat detector used for?

Heat detectors are intended to minimize property damage by reacting to the change in temperature caused by a fire. Smoke detectors are intended to protect people and property by generating an alarm earlier in the development of a fire. People need time to react, and every second is critical during an actual fire event.

How do I test my Fenwal heat detector?

Using a a heat gun, hair dryer, or similar heat source, apply heat evenly to the complete sensing shell. The heated air temperature must be above the alarm set point temperature of the unit. will either close or open which can be verified with a standard OHM meter. Remove the heat immediately after activation.

What type of detector detects fire?

Smoke detectors utilize the smoke in the air to quickly detect fires.

Where heat detectors are required?

In addition, the Building Regulations also require a heat alarm to be installed in any kitchen areas where the kitchen is not separated from the circulation space or stairway by a door. Multi‑sensor alarms are generally more suitable for installation in circulation areas (hallways and landings) next to kitchens.
