Rechargeable

: Fully charged cells can power unit in standby for over 4 weeks.

Lithium Cells:

 

It can power the unit in alarm for over 2 hours. The unit beeps every 40

 

 

seconds if cells are depleted.

Interconnect

: Up to 12, Ei 261EN/261DEN Alarms can be interconnected, so that when

 

 

one senses CO, all alarm.

Relay Module Ei128C

:

This can be connected, using the interconnect line. Use relay contacts for

(optional)

 

for switching valves etc.

CO Alarm Memory:

: A unit will indicate if it has been in alarm previously by flashing the red light

 

 

for 2 seconds every 40 seconds (2 flashes for 50 ppm CO, 4 flashes for 100

 

 

ppm CO and 8 flashes, for 300 ppm CO). When the test button is pressed

 

 

the red light flashes as per table B and also indicates the previous CO alarm

 

 

level detected. The memory is cleared by holding down the test button until

 

 

the red light stops flashing.

Ei 261DEN, Ei 261EN specifications

Ei Electronics is renowned for its innovation in the fire detection and alarm industry, and among its impressive product offerings, the Ei 261DEN and Ei 261EN smoke alarms stand out for their reliability and advanced features. Both models are designed to provide maximum safety and ease of use in residential and commercial settings.

The Ei 261DEN is equipped with a high-performance optical smoke sensor that detects a broad range of smoke particles, making it particularly effective at sensing smoldering fires. Its intelligent design allows it to differentiate between genuine fire situations and false alarms, such as from cooking smoke or steam. This capability reduces nuisance alarms, ensuring that users remain alert but not overly disturbed by non-threatening activations.

On the other hand, the Ei 261EN offers a similar level of performance with slight variations in features tailored to different environments. This model also utilizes a reliable optical smoke sensor but includes enhanced connectivity options for integration with other alarm systems. The Ei 261EN is particularly suited for larger homes or commercial spaces where multiple interconnected alarms can provide a comprehensive safety network.

One of the prominent characteristics of both models is their user-friendly interface. Each alarm is designed with an easy-to-use test button that allows users to check the functionality of the unit quickly. Additionally, these devices feature a low battery warning system that alerts users when it’s time to replace the battery, ensuring that the alarm remains operational at all times.

Another critical feature is the sealed battery technology found in these alarms. The Ei 261DEN and Ei 261EN come with long-lasting batteries that can power the alarm for up to ten years, eliminating the need for frequent battery changes. This design enhances user convenience and ensures uninterrupted protection.

In terms of build quality, both models are constructed to withstand harsh conditions, making them suitable for various installations. Their compact design and modern aesthetics ensure they can blend seamlessly into any environment without compromising on functionality.

In summary, the Ei Electronics Ei 261DEN and Ei 261EN smoke alarms embody advanced fire detection technology, user-centric design, and robust performance. Their features make them ideal for ensuring safety in both homes and workplaces, highlighting Ei Electronics' commitment to innovation and reliability in safety solutions.
