What You'll Learn
PH30 and PH120 are enhanced fire-resistant cables
Fire-resistant cables are essential in fire alarm installations to ensure the system remains operational for as long as possible in the event of a fire. The British Standards recommend specific cabling based on fire resistance testing. PH30 and PH120 are enhanced fire-resistant cables, designed for indoor fire alarm installations.
PH30 cables are made with high-performance silicone rubber and superior low-smoke zero-halogen materials. They are suitable for indoor fire alarm installations where the circuit must be maintained for up to 30 minutes.
PH120 cables are also made with high-performance silicone rubber and superior low-smoke zero-halogen materials. They are designed for indoor fire alarm installations where the circuit must be maintained for up to 120 minutes.
These enhanced fire-resistant cables are ideal for buildings that require a longer fire alarm system activation time. For example, larger buildings may involve a multi-phase evacuation process, so the fire alarm needs to operate for a much longer duration. The cables are tested by being placed directly in a flame and timed until the circuit breaks. This test determines how long the cable can survive in direct heat situations, typically around 830°C.
The performance requirements of these cables meet British Standards and are tested according to various protocols, including EN 50200, BS8434-2, BS8491, BS6387 CWZ, and Annex B of BS8591.
