Why Rechargeable Vanadium Pentoxide Lithium Cells?

The 10Yr+ rechargeable lithium back-up used in the Aico Ei260 series alarms provides the highest performance and most reliable back-up coverage. The precision charging circuit ensures peak efficiency as the cells are constantly ‘topped-up’ from the mains. Laser welded terminals further enhance reliability. They outperform the alkaline and lithium primary batteries currently used in other alarms.
In addition, they are the only cells with a realistic 10 year life expectancy – confirmed by the manufacturer, Panasonic.

Interconnect & Remote Control Feature

Models Ei261ENRC & Ei261DENRC

The Problem
Audibility throughout the home is a priority, as a situation could arise where a CO alarm is installed in a downstairs kitchen, which has a fossil fuel burning appliance within it, and the alarm signal may not be heard in the upstairs bedrooms or indeed other rooms.

The Solution!
Use the interconnect feature on the Aico Ei261ENRC/Ei261DENRC to connect to your existing Ei160RC smoke/heat alarm installation. Then, you must introduce an Ei1529RC Alarm Control Switch to provide control over the whole system.
The interconnect feature allows the CO alarm to trigger all Ei160RC mains smoke/heat alarms installed and vice-versa – giving increased audibility in either a CO or fire situation. If all alarms are sounding, pressing ‘Locate’ on the Aico Ei1529RC Alarm Control Switch will silence all the alarms except the alarm sensing a CO or fire situation. This gives control over the system and allows occupants to select the safest action and/or escape route.
Additionally, if found to be a false alarm, simply press ‘Hush’ on the Control Switch to silence the alarm. The entire alarm system can also be tested regularly by pressing the ‘Test’ switch(see the diagram below).
