5. Maintenance of the WeR@Home

™

System

The WeR@Home

™

system is almost maintenance-free; the only maintenance-oriented activities required for

its continuous operation are:

1. Replacing Batteries – an indication of the need for batteries replacement is provided by both the

WeR@Home

™

Web Application and the WeR@Home

™

Mobile Application utilizing their different status

displays.

2. Cleaning the Smoke Detector’s filter – on a monthly basis, to remove dust that might block the path to

the sensor.

Other than that, there is no other maintenance activity required for proper operation of the WeR@Home

™

system.

5.1.1 Replacing the Central Control Unit Backup Battery

For its operation, the Central Control Unit (CCU) needs a special 3.7V

, 1400

mAh

Lithium Polymer

rechargeable battery (Essence P/N MCBT05001) and a Power Adapter.

To remove an old battery from the CCU:

1. Remove the Power Supply from the mains socket and disconnect its cable and mini-USB™ connector

from the CCU.

2. Remove the CCU’s back cover, to reveal the battery’s and SIM-card compartment, by inserting a finger

nail between the cover and its frame and lift it as demonstrated in Figure 192 above.

3. Remove the battery by lifting its top-facing edge (note that a special bay is provided for this purpose) and

pulling the battery out of the battery cavity, as demonstrated in Figure 193 below.
