What do you do when you don’t know which solenoid valve your customer already has installed?
Very simply, keep a Homplex HD100 Double Control detector close to you.
There are situations where an existing customer needs a methane gas detector replacement. Gas detector replacement is usually done every 5 years, enough time for the original installation team to be totally different, project documentation archived, detector and solenoid valve information unknown, or simply an exceptional situation requiring emergency intervention.
Homplex offers you a quick solution that can be with you anytime: The HD100 Double Control Double Trigger Gas Detector, useful for triggering both 12-24V DC supply voltage solenoid valves and 230V AC supply voltage solenoid valves.

The right choice: 12V DC vs. 230V AC gas solenoid valves in gas detection systems.
Gas detection systems are a crucial component in ensuring safety in various environments, from homes to industries. Within these systems, solenoid valves play an essential role, facilitating the control of gas flow to prevent potential incidents. In the following we will focus on the differences between 12V DC and 220V AC powered gas solenoid valves and the importance of gas detectors in conjunction with them.
For starters, the supply voltage
12V DC gas solenoid valves are often preferred in mobile applications or where the availability of DC power sources is more accessible. The low voltage also makes them safer in the event of an electrical isolation problem in the circuit. 220V AC gas solenoid valves are mainly used in fixed installations such as residential and industrial. The supply voltage is equivalent to that of the electrical mains which simplifies the supply circuit and the tripping method.
Type of installation
If you will be working in an environment where access to DC power is easy and you prefer a more energy efficient option, 12V gas solenoid valves may be a good choice. For fixed or residential installations, 230V-powered solenoid valves are more common and can be easily integrated using the existing mains supply.
Availability of electricity sources
If the installation location facilitates access to DC power, choosing 12V solenoid valves can simplify installation and maintenance.
Availability
Complex solution packages (consisting of solenoid valve, detector, cables, centralisers, etc.) and even customer or installer affinity towards a particular system.
So, which is the right gas detector?
As a plumber, you frequently deal with various gas installations where safety is a top priority. A dual trigger gas detector offers significantly more robust protection compared to a single trigger detector, ensuring a higher level of safety for you and those around you.
As with solenoid valves, gas detectors are also available in a huge variety depending on the intended use and the solenoid valve they will trigger.In the Homplex portfolio you will find alarm-only detectors (without solenoid valve triggering) that connect directly to BMS systems for both 12-24VDC and 230VAC. Wire triggered detectors (same with 12-24VDC or 230VAC triggering) or radio detectors and controllers.
But for the situations for which it was designed, the advantages offered by a dual trigger detector are worth considering:
Flexibility in integration
A dual trigger gas detector can be integrated with both 12V DC and 230V AC gas solenoid valves. This means you can offer customised solutions to your customers, no matter what type of installation they have.
Extended protection
By using a dual trigger system, you cover a wider range of applications and environments. This ensures that gas leak detection and shut-off will occur regardless of installation specifications.
Quick reaction in critical situations
Dual triggering involves two levels of triggering, which increases the responsiveness of the system to risks. In the event of a gas leak, the detector can react quickly and efficiently, ensuring an immediate shutdown of the gas supply to prevent any unwanted incidents even on 2 separate circuits.
Versatility and savings
Did you find 2 solenoid valves with different voltages installed, for example one at the entrance to the house (230VAC) and one in the kitchen (12VDC) before the stove? Install only one detector without replacing the solenoid valves or an additional detector!
Adaptability to environmental change
Installations may evolve and change over time. A dual trigger gas detector offers greater adaptability, being able to handle changes in power supply or solenoid valve specifications without compromising safety.
