Summary
The Hochiki SMB-1 is a module enclosure designed to house Hochiki modules on site, offering 32 metric knock-outs across its long and short sides so you can route cables exactly where the job needs them without reaching for a drill. Supplied with a transparent black lid as standard, it lets you check module status at a glance without breaking the seal.

For an installer working through a commercial fire detection system install, that combination of knock-out choice and a see-through lid means fewer site visits for cable re-routing and quicker visual checks during commissioning and maintenance. The enclosure’s grey polystyrene base and polycarbonate lid are built to withstand the knocks and chemical exposure of plant rooms, car parks and industrial sites.
Fitted with an adaptor plate (sold separately), the SMB-1 can take any PCB from the Hochiki Smart-Fix Module range, or the CHQ-SIM, CHQ-POM or CHQ-SOM mini modules, giving you a single enclosure option to standardise on across a project.
The Hochiki SMB Adaptor Plate is required to fit mini modules such as the CHQ-SIM, CHQ-POM or CHQ-SOM into the enclosure.
Features
- 32 metric knock-outs – routes cables on long and short sides without extra drilling on site
- Adaptor-plate compatibility – houses Hochiki Smart-Fix Module PCBs or CHQ-SIM, CHQ-POM and CHQ-SOM mini modules (adaptor sold separately)
- Quick-release screws – speeds up lid removal during commissioning and ongoing maintenance
- Transparent black lid – allows visual inspection of the module without opening the enclosure
- Polyurethane gasket – seals the base and lid to keep out moisture and dust
- Broad chemical resistance – tolerates weak and strong alkali, alcohol, petrol, benzene, mineral oil, diesel, ammonia, and vegetable and animal oil, useful on industrial and plant room installs
- Impact-resistant, non-flammable polystyrene construction – rated to +70°C for demanding environments
- IP66 rated when supplied with its transparent lid

FAQ
Yes, you’ll need the SMB-ADAPTOR plate, which is sold separately. Once fitted, the adaptor lets the SMB-1 take any Smart-Fix Module PCB, or a CHQ-SIM, CHQ-POM or CHQ-SOM mini module. The mounting plate always requires 4 x M3 countersunk self-tapping screws. A full-size CHQ module PCB is then fitted with 2 x M4 pan head screws and 2 split washers, while a mini CHQ module uses 2 x M3 countersunk machine screws. Yes, the SMB-1 is supplied with a transparent black polycarbonate lid as standard, so you can check indicator LEDs or module status without breaking the IP66 seal. Each long side has one M32/40, two M25/32 and eight M20 knock-outs, and each short side has one M32/40 and four M20 knock-outs, so most standard metric glands will fit. Its polyurethane gasket maintains IP66 protection and the housing is resistant to a wide range of chemicals including alkalis, fuels, oils and ammonia, making it a reasonable choice for exposed or industrial environments. Always check the specific site conditions against the listed chemical resistance before final selection.Do I need anything else to fit a CHQ module inside the SMB-1?
