SVC - PIEZO SCREAMER
Made in Taiwan
FS3807
Nominal supply: 12V DC @ 170mA (although the box indicates a range of 6V ~ 12V is acceptable)
30cm flying colour coded leads (Black & Red)
LOUD! 110dB (See my test results below!)
Two Tone warbling
White "top hat" design
Often used in alarm installations where not only does this device create a VERY LOUD "alarm sound", in enclosed areas it can cause physical distress/disorientation/nausea to the intruder
TESTING:
Being used, I fired up this screamer to make sure all was OK.
Tested with 12V DC, dang! this is one loud beast! Standing about one metre away, my ears were pinging like crazy - I am sure this is not good for your hearing!
No intruder is going to "hang around" with this thing screaming it's head off (unless they are smart and are wearing ear plugs)
COSMETIC CONDITION:
USED Ex installation removal
CLEAN
For all the world it looks "like new" just no original box
NO damage to the unit
NO damage to the wiring
