GFE ZEOS AS HI

Global Fire Equipment ZEOS AS HI Addressable Heat Detector with Isolator

Analogue addressable heat detector from the ZEOS AS series, featuring a built-in short-circuit isolator to maintain loop integrity and ensure reliable performance in GFE addressable fire alarm systems.

Main Features:

• Loop powered, operating voltage range: 17 V – 30 V DC
• Quiescent current: approximately 450 µA
• Alarm current: approximately 4 mA (with LED indicator active)
• Heat detection operation modes: rate-of-rise and fixed temperature
• Integrated loop isolator ensures that the rest of the loop remains operational in case of a short circuit
• Cable size for loop wiring: 0.5 mm² – 2.5 mm²
• Operating temperature: 0 °C to +50 °C; Storage temperature: –10 °C to +85 °C
• Maximum humidity: 95 % RH non-condensing
• Dimensions: Ø 100 mm × 46.4 mm height (including base); Weight: ~92 g (without base)
• Compatible with all GFE addressable control panels
• Complies with EN 54-5 (Heat Detectors) and EN 54-17 (Short-Circuit Isolators)

Notes:

• Each detector occupies one address on the loop and communicates using the GFE addressable protocol.
• Address configuration is done via DIP switches or an external programming tool.
• Installation should follow GFE guidelines to ensure proper isolator and loop operation.
• Ideal for areas where smoke detection is unsuitable, such as kitchens, boiler rooms, or dusty environments.
• Regular inspection and cleaning are recommended to maintain optimal detection performance.
