If Ethernet port communications fail, the i-Sense has an assigned IP address that 
may be incompatible with your current LAN. Reset the i-Sense IP address to the 
default value by simultaneously pressing the RESET and Heartbeat
♡
buttons for
10 seconds. This will also reset the security user name and password to their 
default values. The Ethernet connection will restart after 5 seconds. Then follow 
the 
Ethernet Communications Setup on page 7
to assign a new IP address and
change username and password from default values.
Hard Reset
If the i-Sense fails to respond, press and hold the RESET buttons for 4 seconds to 
perform a hard reset. This will not erase stored event data, but will cause a power 
up event to be recorded.
Planned Shutdown
The i-Sense will normally record an interruption event whenever mains power is 
disconnected. It is often preferable to exclude maintenance shutdowns from your 
site’s power data record. To shut down the i-Sense without recording an 
interruption event, push and hold the Heartbeat
♡
button for 10 seconds, until
the LED blinks rapidly. The i-Sense will automatically restart the next time 
power is cycled, or when the button is held for another 10 seconds.
SHOCK HAZARD: Do not remove the right cover while main voltage is applied. 
The middle cover should never be removed.there are no user-serviceable parts 
inside.
Battery Replacement
WARNING: To reduce risk of explosion or fire, replace only with same battery 
type: Rechargeable NiMH, size AA, 1.2V, 2000-to-3000mAh. Obey polarity 
markings (+ / -)
The i-Sense uses rechargeable batteries to allow continued operation during 
power interruptions. The batteries will last for several years in normal operation, 
but will need to be replaced at some point. Battery health is shown on the i-Sense 
Management Console. The battery cover is located on the bottom surface of the 
i-Sense. Battery replacement may be safely performed while main power is 
applied. To replace or check batteries:
•
Loosen two Phillips-head screws and remove the battery cover to access 
the battery holder.
