About Edwards Detectors Siga Oshd
The Signature Optica Series SIGA-OSHD smoke detectorbrings advanced optical sensing technology to a practical
design that increases efficiency, saves installation time,
cuts costs, and extends life safety and property protection
capabilities. Continuous self-diagnostics ensure reliability
over the long-haul, while environmental compensation helps
reduce maintenance costs.
The SIGA-OSHD provides an optical smoke sensor and a
rate-of-rise heat sensor with a fixed temperature setting.
Together these sensors efficiently detect smoldering fires,
as well as fast flaming fires.
Like all Signature Optica Series detectors, the SIGA-OSHD is an
intelligent device that gathers analog information from multiple
optical sensors, converting this data into digital signals. Utilizing
dual optical wavelengths combined with multiple detection angles,
the SIGA-OSHD differentiates particles that are not representative
of actual smoke. Particle data is input into digital filters which
feed a series of ratios removing signal patterns that are typical of
nuisance sources, thus reducing unwanted alarms. To make an
alarm decision, the detectors on-board microprocessor measures
and analyzes all optical sensor readings and compares this
information to preprogrammed settings.
Intelligent Smoke and Heat Detection
Harnessing advanced photoelectric and fixed-temperature technologies, the SIGA OSHD ensures rapid and accurate identification of both smoke and heat anomalies. Its built-in digital addressable system enhances building safety through precise detector location and status reporting, minimizing downtime and false alarms.
Reliable Performance and Standards Compliance
Manufactured for demanding environments, this detector maintains sensitivity with automatic drift compensation, provides maintenance alerts, and continuously tests itself for faults. Fully compliant with UL 268, ULC S529, CSFM, and MEA listings, it offers peace of mind in adherence to rigorous fire protection standards.
Versatile Application and Installation
Compatible with SIGA series bases, the SIGA OSHD accommodates ceiling or wall mounting on a surface. Its robust design, adaptability, and high IP42 ingress protection make it suitable for diverse commercial, industrial, or institutional settings, with dependable operation even in challenging environments.
FAQ's of Edwards Detectors Siga Oshd:
Q: How does the Edwards SIGA OSHD detector indicate an alarm?
A: The SIGA OSHD utilizes dual red LEDs that deliver 360 visibility, allowing alarm conditions to be seen from any angle, which facilitates quicker identification by personnel.Q: What type of sensor technologies are incorporated in the SIGA OSHD?
A: This model combines both photoelectric smoke sensing and a fixed-temperature heat sensor (preset to 57C or 135F) to detect smoke and rapid temperature changes for comprehensive fire detection.Q: Where can the SIGA OSHD detector be installed for optimal performance?
A: The SIGA OSHD is suitable for ceiling or wall surface mounting in indoor environments such as commercial, industrial, and institutional buildings, using compatible SIGA bases for secure installation.Q: What process ensures the detector maintains its sensitivity over time?
A: The detector features drift compensation technology that automatically adjusts its calibration, maintaining high sensitivity to smoke and heat variations throughout its life span.Q: When does the detector provide self-diagnostic and maintenance alerts?
A: Automatic self-diagnostic routines continuously monitor the detector's performance. Fault or maintenance alerts are reported to the control panel as soon as any abnormality is detected.Q: What are the benefits of using the SIGA OSHD in a fire detection system?
A: Key benefits include reliable smoke and heat detection, fast alarm indication, digital addressable output for precise location tracking, easy maintenance, and adherence to safety standards, contributing to superior building security.Q: Is the SIGA OSHD compatible with wireless fire detection systems?
A: No, the SIGA OSHD operates via a wired digital analog addressable interface on the Edwards Signature Loop and does not support wireless communication.Tell us about your requirement
