GFE ZEOS AD HI

Global Fire Equipment ZEOS AD HI Addressable Heat Detector with Isolator

Analog addressable heat detector, part of the ZEOS AD series, equipped with integral loop-isolator for enhanced reliability in addressable fire alarm systems.

Main Features:

• Loop-powered: 17 V to 30 V DC
• Quiescent loop current: up to approx. 450 µA
• Alarm loop current: approx. 4 mA when LED is illuminated
• Heat detection modes: fixed temperature thresholds (e.g., 55 °C / 65 °C / 75 °C / 85 °C) and/or rate-of-rise
• Integral loop isolator allows the remainder of the loop to remain active if this device’s wiring short-circuits
• Cable size for loop wiring: 0.5 mm² to 2.5 mm²
• Operating temperature: 0 °C to +50 °C; Storage/transport: ?10 °C to +85 °C
• Maximum humidity: 95% RH non-condensing
• Dimensions: Approx. Ø 100 mm × Height ~50 mm (with base); Weight: ~92 g (without base)
• Certified to EN54-17 (Short-circuit isolators) and applicable EN54 heat detector standards

Notes:

• Each detector occupies one address on the loop and supports full device supervision and communication.
• Address setting performed via DIP switches or programmer; after installation commissioning and testing are required.
• The integral isolator improves loop system fault-tolerance—installation wiring must follow instructions to benefit from isolator functionality.
• Suitable for applications where heat detection is required and smoke detectors are not suitable (e.g., dusty, humid or smoky environments).
• Regular maintenance and cleaning recommended to ensure optimal detector performance and reliability.
