No battery test is made during ongoing power failure. An ongoing battery test is interrupted
immediately if a power failure occurs or if battery voltage sinks down below a certain level.
7.4 Battery alarm and reset alarm
The EC II GSM SE sends out a battery alarm to indicate that the battery is bad. The battery
alarm is completely silent and an active battery alarm is indicated by a light signal on the
speech unit and on the central unit.
A battery alarm will be sent out at any of following occasions:
•
Battery voltage decreases a certain level at a regular battery test
•
Battery is mounted with reverse polarity
•
A battery cell has been short circuited
•
No battery is mounted
If a battery alarm has occurred the EC II GSM SE sends a reset alarm at any of following of
occasions:
•
A regular battery test has been done without any problems
•
The reset button S1 on the printed circuit board has been activated
•
A battery reset command is sent via SMS
If a battery is replaced after the EC II GSM SE has sent a battery alarm, you should reset the
battery alarm by pressing reset button S1. If this is not done, a reset alarm will be sent out at
next regular valid battery test, which can take up to 30 days. Until then the product will send a
new battery alarm each 3
rd
day as a reminder. The battery reset can also be done remotely
with an SMS, see section 9.6 below.
The EC II GSM SE has a protection against deep-discharging, which protects from deep-
discharging damages at mains failure. This means that if the battery voltage sinks below a
certain level during battery operation the battery will be disconnected and EC II GSM SE will
be shut off. The EC II GSM SE will be restarted automatically at the return of the mains.
Normally the 1
st
. alarm receiver is used as battery alarm receiver together with the first alarm
code. However, it is possible to send all battery alarms to a special battery alarm receiver.
See section 8.4.5 below.
