Electromagnetic

: Complies with BS EN 50270

Compatibility

 

Test/Hush Button

: Checks electronics and horn.

 

When the unit is alarming, after sensing CO, pressing the test/hush button will immediately stop the

 

horn (the red light will continue to flash). If CO is still present the red light and the horn will turn on

 

again after about 4 minutes. The unit can only be silenced once during a CO incident. At 300 ppm

 

CO the unit cannot be silenced. (With interconnected units, the hush only works on the alarm

 

sensing CO).

Fast CO Test Mode

: Pressing the test button also causes the unit to check for CO, 4 seconds

 

later to facilitate testing in CO gas. It gives 3 beeps and the red light

 

flashes to indicate the CO level, if CO is sensed and then resets.

Initialisation Time

: 70 seconds. On power up red and amber lights flash momentarily to show

 

they are operational.

Operating

: -10°C to 40°C

Temperature

 

Humidity Range

: 15% to 95% R.H. (non-condensing)

Audible Alarm

: 85dB(A) at 3m minimum

Self Diagnostics

: Horn beep and amber fault light flashes every 40 seconds if a sensor fault is found.

Tamperproof

: Screwdriver needed to release from mounting plate. Additionally a tamper-

 

proofing screw can be fitted to mounting plate.

Ei Electronics Ei 261DEN, Ei 261EN manual Sensing CO

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.
