Eaton CBG370S | Intelligent Addressable Call Point | Surface/Flush Mount, Built-in Isolator
£28.41 (inc VAT: £34.09)
Summary
The Eaton CBG370S is an intelligent addressable manual call point designed for Cooper intelligent addressable fire alarm systems. This surface or flush-mounted device combines attractive contemporary styling with practical engineering features, including soft addressing technology that eliminates time-consuming manual configuration during system commissioning. Supplied complete with frangible glass element and dedicated test key, the CBG370S delivers reliable manual fire alarm activation for commercial and industrial premises.
The call point features Eaton’s innovative fast-fit clip-on front cover system, secured by a self-locking mechanism that can only be removed using the supplied special test key. This dual-function key serves both for testing call point operation and accessing the element compartment, providing installers with efficient maintenance capabilities whilst preventing unauthorised interference. The device accommodates both top and bottom cable entry on the backbox, offering installation flexibility across varied site conditions.
Certified to EN54 Part 11 standards and offering IP42 ingress protection, the CBG370S features heavy-duty terminals supporting loop in and loop out connections with full screen continuity. The call point operates across 17-32V DC with minimal quiescent current consumption below 250µA, making it suitable for energy-efficient addressable detection systems. A comprehensive range of accessories extends functionality including protective hinged covers for high-traffic areas, recessing bezels, resettable element kits and spare glass elements for ongoing maintenance requirements.

FAQs
Can the CBG370S be flush mounted as well as surface mounted?
Yes, the CBG370S is designed for both surface and flush mounting applications. For surface mounting, use the standard rear BESA fixing facilities on the supplied backbox. For flush mounting, you can install the device into a standard UK single gang back box, with recessing bezels available separately to provide a neat finished appearance.
What is soft addressing and why is it beneficial?
Soft addressing allows the fire alarm control panel to automatically assign addresses to devices during commissioning, eliminating the need for engineers to manually configure each device address. On systems with up to 200 devices per loop, this feature significantly reduces installation time, prevents addressing errors and simplifies system setup compared to traditional hard addressing methods.
How do I test the call point without breaking the glass element?
The CBG370S includes a dual-function test key that allows you to simulate activation without breaking the glass. Insert the test key into the slot at the bottom of the call point to test operation. The same key is also used to remove the clip-on front cover for maintenance access when required.
What accessories are available for the CBG370S?
A comprehensive accessory range includes protective hinged covers (CXPC) for busy areas, spacer plates (MBGSP), recessing bezels (MBGBEZ) for flush installations, resettable element kits (MBGREKIT) as an alternative to glass, spare break glasses (UBSG) in packs of 5, and additional call point keys (MFBGKEY3). These accessories maximise functionality and adapt the call point for specific applications.
What cable sizes can the call point terminals accommodate?
The heavy-duty terminals accept cable sizes from 0.28mm² to 2.5mm², accommodating standard fire-rated cables including Firetuf, FP200 and MICC types. Separate loop in and loop out terminals are provided, along with dedicated screen continuity connections for proper earthing throughout the detection loop.
Can I use a resettable element instead of the glass?
Yes, resettable element kits (MBGREKIT) are available as an alternative to the standard frangible glass element. The resettable polycarbonate element can be pressed to activate the call point and then reset using the test key, eliminating the need to replace glass elements after activation. This option is particularly useful for training purposes or areas with frequent false activations.
What is the difference between the CBG370S and CBG370WP?
The CBG370S is the surface/flush mounting version with IP42 protection suitable for internal use, whilst the CBG370WP is the weatherproof version rated IP65 for outdoor applications or areas exposed to dust and water jets. Both models share the same core functionality and soft addressing features but the weatherproof version provides enhanced environmental protection.
