requires a Safety Turtle Base
Station, purchased separately.

Except for the battery, this product is warranted
for one year from the date of purchase. The
effects of misuse are not covered by the warranty.
See the Safety Turtle User Guide for customer
support information.
installing the ga-101
Mount the Gate Alarm sensor in accordance
with local codes and/or regulations
where applicable.
1 Confirm the locations of the Gate Alarm
holder, the reed switch and the activation
magnet before proceeding. Note: The reed switch
and the activation magnet
are normally mounted
FRONT facing, but for
latch gaps of more than
1 inch [2.5 cm.] they may
side mounted
need to be side facing.
2 The holder must be attached so the Gate
Alarm is in an upright position. Use two
wood screws to secure the holder to the
top of a wooden fence post or frame. Use
self-tapping metal screws, not included,
to attach the holder to the horizontal top
railing of a metal fence. [If there is no top
railing, a nylon cable tie may be used to
attach to a metal post.] Insert the Gate
Alarm housing into the holder.
3 A mounting template is
provided to locate the
screw holes for the reed
switch and the activation
magnet. Mount the reed
switch to the stationary
frame of the gate using
two screws. Note the
orientation of GRI logo.
Both the [GRI] logos on the reed switch
and the activation magnet must be oriented
in the same direction, up or down.
4 Mount the activation magnet to the moving
frame of the gate, opposite and parallel
to the reed switch, with the GRI logos
aligned. The facing surfaces of the reed
switch and the activation magnet must
not be separated by more than 1.5 inches
[3.8 cm.].
5 The Gate Alarm housing is water resistant,
but not waterproof. Do not immerse it in
water or allow water to enter from the
bottom. Do not remove the foam underneath the housing. It serves to protect
against the elements.

installing the battery
1 To install the battery, remove the
Gate Alarm housing from the holder.
2 Separate the top and bottom halves of the
housing, remove the mylar tape, then firmly
press the battery into place as shown.
3 With the O-Ring and foam underneath
the housing correctly in place, reattach
the top and bottom halves of the housing.
Re-insert the housing into the holder.

operating the ga-101
The Safety Turtle® User Guide that comes
with the Base Station explains the functionality
of the Safety Turtle system and the Base
Station. The following instructions are
supplemental to the Safety Turtle User Guide.
The GA-101 Gate Alarm sensor transmits but
does not alarm locally. Alarming occurs only at
the Base Station, which is purchased separately.
All Safety Turtle sensors [Turtles, Gate
Alarms, and Panic Buttons] must be of the
same color to work with one Base Station.
The Baby Turtle coding plug and sensors
all depict this color.
1 Refer to the accompanying diagram of the
GA-101. Note the positions of the adult
bypass switch [the button on top of the
Gate Alarm] and the LED [the light next
to the button].
2 Before the Gate Alarm sensor can function,
the GA-101 must be installed on a gate
The last step in the installation is to insert
the battery into its holder. Do this when
the Base Station is plugged in, with its
green light on, and is not alarming.
If the Base Station alarms as soon as the
Gate Alarm sensor battery is installed,
check to make sure that the gate is
properly latched.
If pressing the moon-shaped button on the
Base Station does not completely silence
the alarm, the reed switch and magnet
are spaced too far apart when the gate is
latched. Reduce the spacing between the
reed switch and magnet [see INSTALLATION INSTRUCTIONS]. If this does
not work, remove the battery and contact
the manufacturer for assistance.
3 A Base Station will only alarm when it is in
range of the signal transmitted by the installed
GA-101. The range varies to a maximum
of about 250 ft. [75 meters] and must be
tested for each installation. To maximize
range, locate the Base Station as high as
possible and facing the coverage area,
e.g. the pool and/or alarmed gate(s)
[see “Locate the Base Station” in the
Initial Setup and Testing section of the
Safety Turtle User Guide].
4 Test the operation of the system as follows:
a the gate should be latched except
where indicated
b the Base Station should be in Test Mode
with its amber light on [see the Safety
Turtle User Guide]
c the LED on the Gate Alarm should
illuminate for about 11 seconds after the
adult bypass switch on top of the unit is
pressed – if it does not, the battery needs
to be replaced or pressed firmly into its
holder [see Replacing the battery]
Safety Turtle is not a substitute for diligent supervision
or an adequate barrier to restrict the access
of children to water hazards.
d open the gate – beeping should start
immediately and continue with the gate
resting on the latch, and stop within a
few seconds of latching
6 Step 6 is optional if Step 4 was successful.
Repeat Step 4 with the Base Station in
Active Mode [amber light off]. Once the
Base Station alarms, press the moon-shaped
button to turn it off. If the system performs
correctly in Active Mode but not in Test
Mode [see the Safety Turtle User Guide],
the CR2032 battery in the Gate Alarm
needs replacing in the near future.
f after testing, return the Base Station
to Active Mode [see the Safety Turtle
User Guide]
7 If Steps 4 and 6 have both failed, relocate
the Base Station where there is better
reception of the signal from the Gate
Alarm sensor [see “Locate the Base
Station” in the Initial Setup and Testing
section of the Safety Turtle User Guide].
5 If no beeping occurred in 4, open the
gate wider. If this solves the problem, the
spacing between the reed switch and the
magnet needs to be increased very slightly
Repeat Step 4.
8 The 11 second adult entry countdown
only starts when the adult bypass switch
is released. It also resets to 11 seconds
whenever the switch is pressed while the
LED is still on. Hold or press the switch
repeatedly to prolong the timeout.
e press the bypass switch then immediately
open the gate – there is an 11 second delay
before the beeping starts
replacing the battery
Release the battery from the holder as
shown below. Install the new battery per
If the gate has to be kept open for an
extended period, remove the battery to
avoid rapid discharge.

battery holder to eject the battery
