Introduction to the Hochiki CHQ-BACKBOX Module Back Box and its key features
Hochiki CHQ-BACKBOX Module Back Box(catalogue ref. ITM003063) is a purpose-designed weatherproof enclosure that provides a neat, robust home for Hochiki CHQ Smart-Fix modules. Built from colour-matched ABS and engineered so CHQ modules mount directly to the box as the lid, the CHQ-BACKBOX simplifies installations that require glanded cable entries and improved ingress protection. When a CHQ module is bolted to the back box, the assembled unit is reported by the vendor to reach IP65, delivering dust-tight and water-resistant performance for outdoor or exposed-area installations.
Detailed description: specifications and tangible benefits
The CHQ-BACKBOX is a compact but practical accessory aimed at installers who need a protected terminal point for CHQ range interface and I/O modules. Key specifications include:
- Manufacturer:Hochiki
- Model:CHQ-BACKBOX (ITM003063 / catalogue ref. 1670960-00)
- Material:Weatherproof ABS, colour-matched to CHQ module bases
- Knock-outs:Ten knock-outs suitable for cable glands (glands not supplied)
- Compatibility:Designed for the CHQ Smart-Fix range — e.g., CHQ-DIM(SCI), CHQ-SZM(SCI), CHQ-DZM(SCI), CHQ-DSC(SCI), CHQ-MRC(SCI), CHQ-DRC(SCI), CHQ-PCM and other CHQ modules
- Ingress protection:Assembly reported to reach IP65 when used with a CHQ module bolted as the lid (vendor documentation)
- Dimensions & weight:Insufficient data in the supplied documentation — installers should request the instruction manual or technical drawing for precise mounting details
From these specifications come several practical benefits. The ABS construction offers a balance of impact resistance and weather durability, while colour matching keeps the finished installation visually seamless. The ten knock-outs provide multiple options for cable entry and exit, making it straightforward to use glanded entries and meet local wiring/regulatory requirements. Because it is designed specifically for the CHQ Smart-Fix family, it eliminates the need for adaptors or ad-hoc mounting arrangements — the module mounts directly to the back box and becomes the lid, speeding up installation and reducing parts count.
- Facilitates compliance with glanded cable entry requirements — necessary for many outdoor and exposed installations.
- Raises the assembled IP rating (to IP65 reported) reducing the risk of moisture ingress that can cause faults.
- Reduces installation time by allowing direct Smart-Fix module mounting: fewer screws, less fiddly wiring, and a tidy final appearance.
- Cost-effective — compact and focused accessory with an approximate suggested retail price of A9 9.85 (cost price A9 8.27 as supplied) that offers protection and compliance benefits for a modest outlay.
Use cases and scenarios where the CHQ-BACKBOX excels
The CHQ-BACKBOX is a versatile accessory suited to a range of applications in fire alarm and building management installations. Typical scenarios include:
- External or semi-exposed control points:Where sensor or I/O modules need protection from rain, dust, or general outdoor exposure (for example, external pump controls, valve interfaces, or remote annunciator modules).
- Plant rooms and service corridors:Areas with potential condensation, dust, or occasional splashes where IP-rated enclosures prolong service life and reliability.
- Retrofit projects:When upgrading systems to CHQ modules in locations where a pre-existing installation lacks glanded entries or sufficient environmental protection.
- Neat contractor installations:Installers who want a tidy, manufacturer-approved fitting that reduces the need for bespoke enclosures or on-site modifications.
For installers and facilities managers, the CHQ-BACKBOX mitigates common onsite issues: non-glanded cable entries, poor sealing around module edges, and the extra labour associated with adapting generic junction boxes to accept proprietary modules. It is particularly useful on jobs where maintaining the manufacturers recommended ingress protection level is part of the compliance checklist.
Comparison with similar products on the market
Several alternatives exist for housing modules and providing weatherproof terminations: generic IP65 junction boxes (often polycarbonate), metal back boxes, and bespoke enclosures adapted to accept specific modules. Compared to these options, the CHQ-BACKBOX offers a number of advantages:
- Fit-for-purpose integration:Generic junction boxes typically require adaptors, drilling or additional mounting plates to accept CHQ modules. The CHQ-BACKBOX accepts Smart-Fix modules directly, removing those extra steps.
- Visual match and finish:Because it is colour matched to CHQ module bases, the overall appearance is cleaner than a mismatched third-party box.
- Cost and efficiency:While metal boxes are robust and sometimes preferred for mechanical protection, they are heavier, can be more expensive, and often require additional sealing to achieve IP65 for electronic modules. The CHQ-BACKBOX is lightweight and economical while providing the ingress protection intended by the module manufacturer.
- Specialist vs generic:For installations strictly requiring certified enclosures or specialist materials, a more rugged or certificated enclosure might be appropriate. However, for many fire alarm and interface installations where CHQ modules are specified, the CHQ-BACKBOX offers the right balance of protection, compatibility and price.
Customer feedback and installer impressions
There are limited formal public reviews specifically for the CHQ-BACKBOX, which is common for small accessory items. However, installers who use the CHQ family typically highlight a few recurring positives when using matching back boxes:
- Cleaner installations:Contractors report that direct-fit back boxes save time and lead to neater-looking panels and field installations.
- Ease of achieving IP rating:Feedback indicates that using a manufacturer-matched back box and correctly selected glands makes achieving a weatherproof assembly straightforward.
- Fewer on-site modifications:Installers appreciate having a purpose-built option rather than modifying generic boxes, which reduces the risk of damaging components or compromising sealing.
These collected impressions align with the product intent: the CHQ-BACKBOX is not a high-profile, standalone product people review online often, but it performs the specific, practical role installers expect from a module back box.
Conclusion: why the CHQ-BACKBOX is a great choice
For anyone installing Hochiki CHQ Smart-Fix modules in exposed or semi-exposed environments, the CHQ-BACKBOX is a pragmatic choice. It is purpose-built to accept CHQ modules, provides multiple glanded entry points, and improves the ingress protection of the final assembly when used as intended. The result is a tidier, more compliant and quicker installation compared with adapting generic enclosures.
While it is a small and straightforward accessory, its value lies in saving time, reducing on-site modification, and providing a reliable weatherproofing solution that matches the CHQ product family aesthetically and functionally. For contractors, facilities managers, and DIY installers working with Hochiki CHQ modules, the CHQ-BACKBOX is an inexpensive, well-considered accessory that helps ensure installations remain durable and compliant.
Note:Always use appropriate cable glands and sealing methods to preserve weatherproofing, follow Hochiki installation instructions, and consult the CHQ-BACKBOX instruction manual for mounting dimensions. Confirm CE/UKCA and other conformity details with Hochiki documentation and ensure installations follow local fire alarm regulations and standards.
