Wisualarm DHI-HY-HT10A-R8 Wireless heat detector network-compatible, incl. 10-year battery battery-powered (Ø x H) 93.8

The Wisualarm DHI-HY-HT10A-R8 is a radio-controlled heat detector for continuous monitoring of unusual temperature increases in indoor areas. The device uses a high-precision thermistor and an intelligent algorithm to trigger an alarm when a preset temperature range is reached.
The detector is intended for areas in which the influence of smoke, dust or humidity can cause false alarms in smoke detectors, such as kitchens, attics, garages or heating rooms. The application scenarios include households and similar living areas such as kitchens and garages.
When an alarm is triggered, the signal is forwarded to all linked devices in the wireless network so that the networked detectors can be alerted together. The radio network supports up to 24 devices.
The heat detector offers a test and mute function via the central push button. In addition, the mute function can be triggered with a functioning infrared remote control. The mute function is 9 minutes.
Power is supplied by a permanently installed, non-replaceable 3 V CR123A lithium battery with a specified battery life of 10 years. LED displays inform about operation, alarm and faults; in addition, a low battery warning is supported.
The detector can be paired with a separate Wisualert WLAN Base Station DHI-HY-GW01A and used with the Wisualarm APP. The base station serves as a central connection unit for compatible Wisualarm and WisuLink wireless products and enables the APP connection of the networked detectors. When an alarm is triggered, the detector emits an alarm signal; in addition, push notifications can be transmitted to a smartphone in combination with the base station. Up to 24 compatible WisuLink wireless products can be integrated per base station. The coupling is done via the pairing button on the gateway as well as the TEST/MUTE button on the respective detector. The base station is not included in the delivery and is available separately.
