Panic Alarm
This alarm is triggered by an interior backlit button, besides the
door opening. When pressing this button, an audible alarm
(about 80 dB) from the keypad and from the external grey buzzer
will occur. The display will also show the message EA (External
Alarm) alternatively with the actual temperature. The 115 Volt
alarm signal will turn ON. This alarm will be active as long as the
panic button is pressed.
Note that the gray external buzzer connected to the emergency
alarm is powered only by the battery backup power. It is
important to periodically check the condition of the battery and
the backup power. It is important to periodically check the
condition of the battery and the backup power because once the
battery dies, no external sound signal will be triggered with the
activation of the emergency alarm push button.
Muting an alarm
Pressing the ''Silent'' button on the keyboard (top left), during
an alarm, will mute the audible signal but the associated alarm
message and the 115 Volt signal will remain until the alarm
condition disappears.
Alarm Annunciator
This additional buzzer (about 90dB) is ideally suited for hearing
any of the I3 alarms in a noisy environment. It is muted
independently from the keyboard Buzzer, by its own Mute
button. This annunciator is not supported by the back-up battery.
Note that at the request of the client on site, this additional
audible warning can be surface mounted to the desired location
(see I3 wiring diagrams for details). Without special request, it will
be installed near the I3 Intelligence module.
Fan failure alarm
When a ventilation system circulates air in concealed spaces
around the exterior of walk-in cold rooms, optional sensors can
be supplied to monitor the presence of air flow on each blower.
If air flow stops, the system triggers an audible alarm and
displays a message on the keypad. The display will also show the
message EA (External Alarm) alternatively with the actual
temperature. Without grey external alarm (Different from Panic
Alarm).
The 115 Volt alarm signal will be active as long as the failure
exists. When this alarm is ON, the Alarm LED on the left of the
display will ON.
Battery back-up
The 9 Volt battery holder is located just above the controller. In
normal condition, an alkaline battery should maintain the
temperature display and the alarm messages in operation during
power outages for 24 hours, depending on the battery condition.
As this battery is not rechargeable, it shall be replaced yearly or
every time there is a power outage lasting more than one hour.
The battery only supports the controller display and the local
Panic Alarm, via the grey buzzer. This battery's condition must be
checked periodically.
The external 115 Volt alarm signal is not supported by this battery
back-up. If it is a requirement to have an external alarm signal on
power outages, the Dry Contact signal option, with proper
parameter settings, is required to achieve this functionality.
Three-way Switch for Lighting
This option allows to control lighting through two different door.
The three-way switch for lighting can be in automatic of manual
mode. For each lighting mode, cable configurations and,
positioning of hardware and distinct metrication is required. You
must refer to the I3 wiring diagrams for the proper electrical
connection according to the lighting mode selected. By default,
the three-way switch is in automatic mode. The configuration in
three ways manual mode is only on demand.
Note that the open door alarm will be disabled with the three-
way switch for manual lighting.
Dry Contact for External Alarm signal
The standard external alarm is a 115 Volt signal. As an option, it
can be converted to a dry contact (Normally Closed) that opens
an alarm signal (see I2 wiring diagrams for more details). This
option also includes a normally open contact if it needs to be.
Glycerine Immersion
Having the temperature probe immersed in glycerine prevents
rising temperature readings and false temperature alarms due to
the opening of the door.
