SEC-B v4 Boiler Room Gas Pressure Proving System
The SEC-B is a multi-function solution designed for boiler rooms. The panel can monitor up to 6 detectors directly and up to 16 when installed with an AD-PP power pack.

Gas Pressure Proving
Using the patented differential pressure proving method the system checks the gas pipework and appliances in a kitchen for gas leaks. It also monitors for low pressure and overpressure without opening the solenoid valve, making it the only truly safe method of proving available.
Auto-restart after power failure and fire alarm
The SEC-B can auto reset after an electricity supply failure or after a fire alarm has been manually reset when used in boiler room applications. This enables a building heating system to restart without manual intervention, minimising the chance of frozen pipes and a cold building.

SEC-B v4 Boiler Room Gas Pressure Proving System Warranty and Service

All our products come with a 5-year warranty
Medem’s industry leading five-year warranty is a demonstration of the company’s confidence in the quality and design of its products.
This applies to the main panels and sender units, gas detectors carry a 2-year warranty.

Why not let us install your system and receive a 10-year Warranty?
Where we’ve commissioned an installed system, the warranty is extended from five to ten years. At the time of commissioning, photos and gas pressure readings are recorded along with other relevant details of the installation. A 24-hour helpline number and the serial number is attached with the panel and all details are then entered on to the Medem database.
Service
The panel and sensors must be re-commissioned and tested every 12 months as a minimum but with consideration of every 6 months dependant on gas type and environment. Medem offers cost-effective yearly service plan options which include detector exchange to assist in service budgeting
