PREPARATION  
INSTALLING A BATTERY  
Your alarm requires one 9-volt battery (not  
supplied) for power. For the best perfor-  
mance and longest life, we recommend an  
alkaline battery, such as RadioShack Cat.  
No. 23-553.  
Cautions:  
Use only a fresh battery of the  
required size and type.  
Follow these steps to install the battery.

1. Use a Phillips screwdriver to remove  
the screw from the battery compart-  
ment cover, then slide the cover off.  
2. Snap the connector over the 9-volt  
battery’s terminals and place the bat-  
tery in the compartment.  
3. Replace the cover, then reinsert and  
tighten the screw.  
When your alarm operates erratically or  
the volume decreases, replace the battery.  
Cautions:  
• Dispose of the old battery promptly  
and properly. Do not burn or bury it.  
• Always remove an old or weak bat-  
tery. Batteries can leak chemicals that  
can destroy electronic parts.

MOUNTING THE ALARM  
Your alarm is designed for mounting on  
non-metallic doors and windows only. It  
uses a magnet to trigger the internal alarm.  
Mounting on metal surfaces can interfere  
with proper operation of the magnetic sen-  
sor.  
Selecting a Location  
For proper alignment, you must mount the  
alarm and magnet so the magnet rests  
with its arrow pointing toward the alarm’s  
engraved line. Choose a location that lets  
you install the magnet on a door or window  
and the alarm immediately next to it on the  
frame, or vice versa. The distance be-  
tween the alarm and magnet must be no  
more than 1/3 inch (8 mm).

Screw Mounting  
illustration  
1. Using the supplied drilling template,  
mark the screw center points for both  
the alarm and magnet. You can drill  
starter holes to make it easier to insert  
the screws.  
2. Thread screws (supplied) into holes A  
and B until the screws’ heads extend  
1
about /8 inch (3 mm) from the mount-  
ing surface.

3. Line up the keyhole slots on the back  
of the alarm with the screws, then  
slide the alarm down onto the screws  
to secure it.  
4. Remove the bat-  
tery compartment  
cover and the bat-  
tery. Then thread  
a screw into hole  
Illus.  
C inside the com-  
partment. Rein-  
stall the battery  
and replace the  
cover.  
5. Use the two remaining screws to  
mount the magnet so its arrow points  
toward one of the engraved lines on  
either side of the alarm.

Adhesive Tape Mounting  
1. Clean and dry the mounting surfaces  
for both the alarm and the magnet.  
2. Peel the backing off of one side of  
each of the supplied adhesive strips,  
then attach them to the back of the  
alarm and the magnet.  
3. Peel the backing off of the other side  
of the alarm’s adhesive strip. Press  
the alarm firmly against the window,  
door, or frame where you want to  
mount it. Hold the alarm in place for  
about a minute to secure it.  
4. With the magnet’s arrow pointing  
toward one of the engraved lines on  
either side of the alarm, repeat Step 3  
to attach the magnet.

OPERATION  
USING YOUR DOOR  
ALARM  
Illustration that was on  
the front cover of the O/M  
with callouts to Key Switch  
and Mode Switch.  
A pair of keys is provided to operate the  
Off/On  
key switch. When the alarm  
10  
 
49-421a.fm Page 11 Thursday, August 19, 1999 7:48 AM  
sounds, silence it by inserting a key and  
setting the key switch to Off.  
Instant Alarm  
To arm the alarm while you are at home,  
set the mode switch to Instant Alarm and  
set the key switch to On.  
The alarm sounds if the secured door or  
window is opened and the magnet moves  
away from the alarm unit. The alarm con-  
tinues to sound until you set the key switch  
to Off.

Delayed Alarm  
To arm the alarm when you leave the  
house, set the mode switch to Delayed  
Alarm and set the key switch to On.  
Once the switch is set to On, there is about  
a 15-second delay before the alarm is  
armed, giving you time to go out and close  
the door.  
When you return home and open the se-  
cured door, you have about 12–18 sec-  
onds to disarm (turn off) the alarm.  
Otherwise, the alarm sounds until you set  
the key switch to Off.

CARE  
To enjoy your RadioShack Door Alarm for  
a long time:  
• Keep the alarm dry. If it gets wet, wipe  
it dry immediately.  
• Use and store the alarm only in nor-  
mal temperature environments.  
• Handle the alarm gently and carefully.  
Don’t drop it.  
• Keep the alarm away from dust and  
dirt.  
• Wipe the alarm with a damp cloth  
occasionally to keep it looking new.  
Modifying or tampering with the alarm’s in-  
ternal components can cause a malfunc-  
tion and might invalidate its warranty. If  
your alarm is not performing as it should,  
take it to your local RadioShack store for  
assistance.
