Zeta MKII-OH MKII Fyreye Conventional Optical-Heat Detector
The Zeta Fyreye MKII-OH Optical-Heat Detector combines optical smoke detection and fixed-temperature heat sensing in a single conventional detector. Compliant with EN54-5 & EN54-7, it’s ideal for zones where both smoke and heat risks exist, such as hotels, offices or storage warehouses.
Key Features
-
Dual sensor design: optical chamber for smoke plus thermistor for fixed-temperature (57 °C) heat detection.
-
Certified to EN54 parts 5 & 7 with LPCB approval (CPD 0845-CPD-232.1703).
-
Low current consumption: standby approx. 40 µA; alarm current approx. 34 mA @ 24 V DC.
-
Wide operating range: 9-33 V DC supply voltage range; operating temperature -10 °C to +50 °C.
-
Lockable base prevents unauthorized removal, and remote LED output available for status monitoring.
-
Compatible with all Fyreye MKII bases (common, diode, deep) for straightforward installation and replacement.
