This is the same model alarm as our Highly
Reliable Highly Popular Model. The difference
being is that this alarm is a less expensive
second tier version. Although it comes off
the same production line as the Top Tier
Model, this alarm just isn't quite as loud.
The above makes more sense to you when
you understand there is wide variation in the
loudness of
All Piezo Alarms
coming off the
same production line. The loudest alarms sell
at premium prices since they are more efficient
and just happen to be produced in much
smaller quantities.
I've tested a lot of different mini alarms, and
found this alarm to have the best track record
for performance and reliability. And to further
maximize buyer satisfaction, I test every alarm
before I ship it. I'm proud to say that I've never
had an alarm returned because of defects or
buyer dissatisfaction.
For Getting the Maximum Sound Out Of This
Alarm, You'll Need a Good 12V Power Adapter.
If you need such an adapter, I can recommend
a good power adapter to you that I have
personally tested on this alarm.
If Shopping for a "Top Quality" Alarm, it's
important that you take time to read the
next paragraph below.
As you probably suspect, most other piezo
alarms are made in China where quality
control isn't even an afterthought. But
these alarms are different. I have yet to
have any complaints with these alarms. All
the other Chinese made alarms I tried had at
least a 5% Failure Rate; and the performance
of most of those was poor to mediocre at
best. The design and manufacturing of
most the Chinese made alarms also left a
great deal to be desired, with some even
having loose parts inside that rattled,
and/or other imperfections in the case and
assembly. This Alarm was made in Taiwan
and is just better quality than all the other
Chinese Made alarms we tested.
Warble Definition:
Similar to a Siren, the pitch of the sound rises and falls
linearly in a repeating pattern.
It produces a Very Loud, Medium-Slow Warbling
type sound, and it only draws about 110ma at
12 Volts. The unit I tested even ran on as little
as 6 Volts at a somewhat reduced volume level.
I don't know if all units will perform at voltages
this low or not, but I will be happy to test a unit
for you at what ever voltage you request. Just
send me an email before you buy specifying the
voltage you would like me to test the device at.
Please Note:
The maximum advertised sound level will only
be produced when powered by a 12V source.
Lower operating voltages will result in lower
sound levels being produced. This is true of all
piezo alarms, not just this one. That's just the
way it is being subject to the Laws of Physics.
Also Note:
This is just a Sounder and requires a
connection to a voltage source. It does not
have a built-in triggering mechanism,
battery, or automatic shut-off.
Usage Considerations:
Since this is a Mini Alarm having Low Power
Requirements and a Small Diaphragm, this
alarm may not be suitable for outdoor use
where a large coverage area is desired or
the sound needs to carry great distances.
BEWARE:
It's common for Chinese manufacturers
and other sellers to make False Claims
on the DB Sound level produced and
the Watt rating of the amplifier that is
producing the sound. But here is how
you can tell when false claims are being
made:
Find the listed current rating of the
alarm in the ad and multiply that value
(in amps) times the alarm's maximum
voltage rating. If your calculation is much
less than the seller's stated Watt rating,
you cannot trust the specs the seller has
listed for his alarm. If the seller's ad does
not list the alarm's operating current, that
can also be a clue that the seller does not
want you to know the truth about his alarm.
This alarm's power consumption is about
1.32 Watt (.11 Amp x 12V = 1.32 Watt).
That is typical for piezo mini alarms
of this size, yet you will find some
eBay sellers advertising these kind of
mini alarms as 10 Watt, which is a
HUGE LIE! Know what you're buying
and if you can trust who you're buying from.
