SEC-B v5 Boiler Room Gas Pressure Proving and Detection System
The SEC-B v5 can monitor up to 6 detectors directly and up to 16 when installed with a power pack, includes pressure proving to allow auto-resetting in the event of a power failure.
The SEC-B v5 is a gas pressure proving and gas detection system with options for electric isolation and ventilation interlocking.
The system will perform a down stream integrity check ensuring gas tightness before use, close the gas solenoid valve in the event of a high-level gas alarm, low incoming gas pressure or if the emergency stop/fire alarm is activated.
It is designed for use primarily in boiler rooms.
Gas Pressure Proving
Using our patented differential pressure proving method the system checks the gas pipework and appliances in a boiler room 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.
Gas Detection
Up to 16 gas detectors can be connected to the system, low level alerts will cause a audible tone and visual message on screen, high level alerts will additionally isolate the gas supply.
Remote Indications
All system states and alerts can be remotely monitored and indicated via our “BMS” relays. There are five potential free relays each of which can configured separately.

SEC-B v5 Gas Proving and Detection 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 commission 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 dependent on gas type and environment. Medem offers cost-effective yearly service plan options which include detector exchange to assist in service budgeting
