The EATON CB2E is the standard base designed for the conventional detectors of the Eaton UL range, used wherever conventional detectors are installed.
In short
- Base for UCPD-2W / UCPT-2W / UCHT-2W.
- Within the UL listing for the conventional detectors (file S35887).
What the base does
It carries the conventional detector and connects it to the zone circuit monitored by the ULMIU872.
Technical data
| Item | Value |
|---|---|
| Model | CB2E |
| Compatible with | UCPD-2W · UCPT-2W · UCHT-2W |
The critical point: compatibility
Use only with the listed conventional detectors of the Eaton UL range.
General notes on sensor layout
- Spacing: spot smoke detectors on smooth ceilings are typically laid out at a nominal 30 ft (9.1 m) per NFPA 72, and heat detectors at their listed spacing (50 ft for this range); spacing reduces for high, beamed or sloped ceilings.
- Air movement: keep smoke sensors at least 3 ft (0.9 m) from supply air diffusers, as the airflow can push smoke away from the sensor.
- Type selection: smoke for offices, rooms and corridors; smoke with heat where fast fires are expected; heat for kitchens, car parks and generator rooms with dust or fumes.
- Sensors in lift lobbies and machine rooms are typically used for elevator recall, and duct detectors for HVAC shutdown, per the governing standards.
- Periodic testing: sensors are functionally tested annually and sensitivity-tested periodically per NFPA 72 Chapter 14, with listed test tools.
General engineering notes
These points are general principles from NFPA 72 and common design practice, not from the EATON datasheet. The final decision rests with the project’s approved designer per the adopted edition of the standard and the authority having jurisdiction.
Installation steps
- Fix the base and wire the zone circuit.
- Fit the detector and test the zone from the monitor.
Common mistakes
- Using it with addressable sensors.
Inspection and maintenance
Before any test or maintenance, notify the owner, the monitoring station and everyone affected, as testing may operate alarms or linked outputs. The owner is responsible for inspection, testing and maintenance per NFPA 72 and the authority having jurisdiction, preferably by a qualified company.
Files and ordering
The EATON UL catalogue is attached. When ordering, state CB2E.
How to order
Use the “Build your order” section on this page: add every model and quantity, then send the whole order by email or WhatsApp. It reaches us as a tidy PDF request sheet and we contact you with the quotation.
FAQ
Does it suit addressable sensors?
No, addressable sensors fit the UCAB300 or ULMAS850.
