EN: Installation Sheet
Enrolling
Each keyfob is learned in to a control panel as an
unsupervised sensor and uses one available zone slot. For
80+ receivers like ZeroWire, learn-in the device by pressing the
“lock” and “2” buttons simultaneously. Please refer to your
specific control panel installation manual for full instructions.
Operation
This button's function depends on the individual panel
programming. Refer to the installation instructions for your
panel.
Panic and Aux
If the keyfob is programmed using a panic group number,
pressing the buttons and simultaneously will activate an
audible or silent panic alarm (depending on a group number)
and initiate reports to the central station.
Arm - Lock
Press once for Arm-Away mode.
Disarm - Unlock
Press this button to disarm your system. You do not have to
enter your access code when you use this key to disarm the
system.
Press once for Arm-Stay mode, twice for Stay Instant mode,
three times for Stay Night mode.

Similarly, if the keyfob is programmed using a portable
auxiliary group number, pressing the buttons and
simultaneously will activate an audible or silent auxiliary alarm
(depending on a group number) and initiate reports to the
central station.
LED indications
Every event sent from the keyfob to the panel is signaled with
a single flash of the green LED.

Also, the following panel events are transmitted to the keyfob,
and indicated by the keyfob's LED state:
System status LED indication
System disarmed Green flashing LED for 1 second.
System armed (away and stay) Red flashing LED for 1 second.
System in alarm (intrusion event,
life safety)
System trouble (can’t arm) LED flashes yellow for 1 second.
Keyfob low battery LED flashes yellow 3 times.
LED alternates flashes between
red and green 2 times, then stays
red for 3 seconds indicating an
alarm condition.
In case the user is out-of-range of the receiver, this will be
indicated with the LED flashing yellow 2 times.
The keyfob will send a low battery signal when the battery
voltage goes below 2.2 V and it will also be reported to the
panel if the keyfob is learned into the panel.
Stay mode options
Single press of the button makes the normal Stay mode
active – interior zones are bypassed.
If you press the button again, Stay Instant mode activates −
your entry/exit delay zones will not be bypassed anymore and
will become instant.
If you press the button a third time, Stay Night mode activates
− in addition to entry/exit zones, also zones set up as "night
zones" will become instant. This prevents even authorized
users from entering the protected area unless it is disarmed
first (for example by someone inside the Stay area).
Replacing the Battery
Because keyfobs are non-supervised devices, a low battery
signal will only be received by the control panel when the
device is within range of the receiver and a button is pressed (if
the device is not in use, no low battery signal will be sent until
a button is pressed). When the device is carried beyond the
range of the receiver and/or is seldom used/tested, the battery
could wholly deplete without a warning of the battery condition
being sent to the panel. If the LED on the device appears dim
or does not turn on when a button is pressed, it is a warning
that the battery may be low or depleted and should be
replaced. To ensure proper functionality, test the device weekly
and follow these simple steps to replace the battery when
necessary:
1. With a key or small screwdriver, press the black tab
located at the bottom of the remote (Figure 1) and slide
the chrome trim off.
2. Carefully separate the front and back piece of plastic to
reveal the battery.
3. Replace with a CR2032 battery ensuring the + side of the
battery faces up (Figure 2).
4. Re-assemble the plastics and ensure they click together.
5. Ensure the notch in the chrome trim is aligned with the
back of the plastic. It will only go on one way (Figure 3).
