IEC 60073 Sixth edition 2002 Chapter 4.2.3
“Coding by changing of characteristics over time”
Alarm sound at 3.3 kHz and maximum sound level of 90 dB.
With IDEC’s unique resonant design, the SignaLight has a
frequency that is most sensitive to the human ear and sends a
clear sound over 360 degrees. Therefore, the sound recognition
is improved as the alarm can be heard in a noisy environment,
enhancing safety.
Flashing cycle complies with IEC standards [1.75 Hz (approx. 105 times per second)]
Unique powerful design with 360-degree sound eld.
Two alarm sound patterns available.

Comparison of alarm pressure from 1m distance
(sound pressure: maximum)
The alarm can be heard from all directions as the
sound spreads out evenly.

Three different illumination methods and a unique lens shape enable high vis-
ibility from all directions.

Condensing lens
(spo llumination)
By combining a diffusing lens,
which diffuses the light broadly,
with a condensing lens, a super
bright area is created enabling
high visibility. Also, the illumination
through the light guide enhances
the visibility when the SignaLight
is viewed from below.

Clear lens type
Because a reective mirror is not installed in the the
LED unit, diffuse reection does not occur from light
disturbance or from strong light. Also, when the clear
lens type is used, the visibility difference between
when the light is on and when it is off is apparent even
in a bright environment.
