The Neptune re-settable call points feature LED illumination, an internal buzzer, and three NO/NC relay outputs. This triple-pole call-point ('break glass' unit) benefits from state-illumination, the optional internal sounder on the event of trigger and a re-settable window with no breakable glass, meaning you don't need to replace the glass each time the call point is triggered.

The illumination indicates the current state of the outputs - during 'standby' the unit will be lit green, and whilst operational, the unit will be lit red, as demonstrated in the photos available.

Inside the call-point, you have an array of options available to you, with regards to the LEDs and internal buzzer. The LEDs can be switched between blinking, continuous or completely off. Similarly, the internal buzzer can be set to buzz in intervals, continuously, or indeed off completely. The volume here can also be adjusted via a 180 degree volume control pin.

Where most call-points will have only one or two outputs to send a trigger to a fire alarm panel, this unit has three outputs, known as 'triple pole', allowing the unit to conduct more than one action when activated. You may wish to release a door lock and a set of magnetic hold-open devices whilst also sending the trigger to the alarm panel.
