Mallory’s 22mm Panel Alarms + LED Light

After determining the voltage range, sound level, & sound type needed, there are 5 LED colors to choose from.  The final option is to add a sound on-time if needed. This feature is used for those applications where it is desired to silence the audible sound after 15 or 30 seconds while leaving the LED flashing so the operator knows that the machine issue is still present.

Most ZT models are configured where the alarm sound & LED light are activated simultaneously. For example, a continuous tone model has an LED which is also continuously lighted, and for a fast pulse tone model, the LED flashes at the same quick rate as the pulsing sound.

For those applications which require the audible alarm & LED to function separately, Mallory offers models which have a 4-position terminal block with two of them controlling the LED, and two of them controlling the sound. This means the sound & light are controlled independently of each other, and the machine has total control of the device’s sound & light activation.

     This true 2-in-1 panel indicator saves space on the control panel, saves installation time & cost, and can provide a material cost savings since only one audible & visual device is purchased rather than buying a separate panel alarm and panel light.
