Guide to IP Rating for Security & Fire Alarm Device

What and Why is IP Rating Important for Security and Fire Alarm Devices

IP rating, also known as International Protection Marking or Ingress Protection Marking, is an internationally recognized standard to define protection from foreign objects. For fire alarm and security devices, each part varies in their requirement according to its placement. Outdoor objects such as sirens, PIR detector often need to be water-resistant, while indoor smoke detectors are more lax.

IP Rating Classification and Relation to Fire Alarm & Security Device

The rating is defined by IP followed by 2 numerical digits, for example: IPXX

The first numerical digit defines the level of protection against solid objects such as hands, conductors, rocks. The levels are defined as below:

The second digit defines the level of protection against water, as listed below:

 
Ingress Protection Requirement for Fire Alarm Siren and Smoke Detector

For outdoor siren, IP55 would suffice and protect against most natural elements such as rainwater or moisture. For fire detectors, because it is mostly placed indoor and meant for detecting smokes, IP33 or IP21 would be enough for protection.

Most of our signaling products are time tested and able to achieve a high IP rating for outdoor use. Some can even achieve waterproof for underwater use. We can offer siren and alarm products with specialized construction to meet your requirement.
