Hytera HR655 High Power 25W TX Compact DMR Repeater VHF

Hytera's HR655 is the new generation DMR repeater designed to expand the communication range of your DMR radios. Compact and lightweight, the HR655 can be flexibly mounted to the wall or carried on the back via tailored accessories. The HR655 allows the communication connection to be available anywhere you need. It is the top pick for hotels, office buildings, supermarkets, industrial parks and many more large scale industries.

FLEXIBLE DEPLOYMENT

The innovative structural design gives the HR655 an unprecedented appearance and lightweight performance. With the compact body and built-in duplexer, the HR655 greatly conserves space. With tailored installation accessories, flexible installation can be achieved on sites with challenging space availability. Site installation is possible as long as there is a wall or flat surface. For indoor coverage, the super slim size of the HR655 minimises the requirements for the site and provides trustworthy voice and data communications as well as offering unlimited connections on each floor which are the keys to achieving your business success.

IP CONNECT

From the dual or multi channel single site DMR conventional system for low-rise buildings to IP Multi-site system for high-rise buildings, the HR655 delivers a powerful and stable signal to every corner of your workplace. It can also interconnect with other model repeaters from Hytera, building a tailored network to meet your variable requirements.

HIGH RELIABILITY

Designed to operate on an AC power source or an optional battery, the HR655 can keep running in the event of a power outage. When it connects to the AC power supply, the battery works as a backup. In case of an outage, the 12.5Ah battery is ready to power the HR655 for up to nine hours of backup time. This power backup solution reduces the capital investment and maintenance for adding UPS power equipment.

SMOOTH TRANSITION

The HR655 can operate in analogue mode, DMR mode, or dynamic mixed digital/analogue mode, which automatically switches between analogue and digital based on the call it receives. The HR655 can ensure that your original analogue radio continues to be connected to the DMR network and protect your legacy system investment to the greatest extent.

CONVENIENT MANAGEMENT

Thanks to the Extended Network Management System (XNMS), you can remotely monitor the operation status and alarms of the HR655 in real time, or update the configuration in minutes. This dramatically reduces the time and resources required to maintain various, dispersed repeaters.

LONG BATTERY LIFE

The HR655 can be equipped with a 12.5Ah large-capacity battery for use in outdoor scenarios, which can provide up to 9 hours of power supply under the RF power output of 10W. Even if the device is used at 50% duty cycle at 25W full power, the HR655 can still guarantee 4 hours of uninterrupted work protection, providing you with a lasting, uninterrupted communication guarantee.
