Information About SIGA-IPHS
The SIGA-IPHS is part of the EST Signature Series, which integrates advanced multi-criteria sensing for reliable performance in varied environments. It analyzes ionization, photoelectric, and thermal inputs individually, applying time as a fourth dimension for more precise alarm decisions. Its microprocessor-driven intelligence reduces communication traffic with the control panel and allows stand-alone operation if loop communication fails. The detector supports automatic device mapping, electronic addressing, and environmental compensation, ensuring long-term stability and reduced maintenance needs. Compatible with standard, relay, isolator, and audible bases, it offers flexible installation options across a wide range of building types.
Key Features:
- 4D Detection Technology: Uses ionization, photoelectric, and heat sensors with time-based analysis for improved accuracy.
- Reduced False Alarms: Digital filters and adaptive algorithms minimize unwanted activations.
- Intelligent Addressable Device: Communicates directly with Signature Loop Controllers for precise identification.
- Automatic Environmental Compensation: Adjusts sensitivity to counteract dust, humidity, and aging effects.
- Electronic Addressing: Eliminates manual switches or dials, configured via programming tools.
- Pre-Alarm Capability: Supports up to 20 sensitivity levels to provide early warning before evacuation.
- LED Indicators: Green for normal operation, red for alarm, with visibility from any direction.
- Flexible Mounting Bases: Compatible with standard, relay, isolator, and audible bases for versatile applications.
The SIGA-IPHS delivers the reliability and precision required for modern fire detection in large-scale facilities.
