Proton

AlArm annunciators

Based on latest single chip micro-controller technology.
Compact design for reliable and accurate operation.
Fast response time.
Field selectable operational sequences.
Incorporates a group of super bright LED's instead of twin Filament lamps for ultimate life at very less power consumption.
Actuated through potential free fault input contacts.
Fault input contacts NO/NC site selectable by means of DIP switches.
Optic isolated all fault inputs, immune to noise disturbances.
Provision for external audible (Bell or Hooter) through' potential free relay output contact.
All models are with built-in Test, Silence(optional), Accept & Reset push buttons, provision on back side terminal strip.
Specially designed power supply for high noise immunity,
Wide input variations & having built-in transient protection.
The extensive protection so provided safeguards all I.C.'s & components from failure, thereby offering complete reliability.
Rugged Plastic enclosure with high strength.
Type tested for noise, impulse and functional test as per various standards.
