The Zeta Fyreye MKII-HR is a conventional rate-of-rise heat detector (EN 54-5 Class A1R) for use on conventional fire alarm zones. A thermistor arrangement senses a rapid rise in temperature and also gives a final fixed threshold alarm at 57°C.
Key features
- Rate of rise plus 57°C fixed heat threshold
- Designed to meet EN 54 requirements
- Lockable to base to prevent unauthorised removal
- Remote LED output
- Compatible with all Fyreye bases: standard or deep, with or without diode (MKII-CB, MKII-CB/D, MKII-DB, MKII-DB/D)
