Maintenance
For personal safety, lock out and tag
out the associated circuit breaker
disconnect for the source of 120V AC power.
Attention:
Pour votre sécurité personnelle, verrouillez et étiquetez le
sectionneur du disjoncteur associé pour la source
d’alimentation de 120 V CA.
For personal safety and to avoid
damage to the alarm, ensure that the
circuit breaker is in the OFF position.
Attention: Pour
votre sécurité personnelle et pour éviter d’endommager
l’alarme, assurez-vous que le disjoncteur est en position

Cleaning
Be sure to use a microfiber cloth or soft lint-free cloth
when cleaning any smudges off of the HMI. Do not
use a paper towel or tissue paper, wet or dry. Do not
apply an excessive amount of pressure to the screen to
prevent cracking.
Battery
The alarm panel includes an onboard battery to
maintain memory in the event of a power outage.
Low battery power will trigger an alarm – replace with
a standard CR2032 battery.
NOTE:
In this particular case, the AC power to the alarm
panel must be kept on during battery replacement.
Otherwise all saved settings will be lost if the battery is
removed while power is disconnected
Maintenance Mode
Toggling the Maintenance Mode button will allow
settings to be changed on the alarm panel without
triggering an audible alarm. Maintenance mode is
automatically turned off after 15 minutes. A timer is
shown near the button once it’s activated. On the main
screen, the Green “Normal” bar changes to Yellow
“Maintenance.”
