Description
The Dahua HY-L121 is a wireless manual call point using LoRa radio (470–510 MHz) that joins an addressable fire system through the WG-1037 gateway without any cabling. Range reaches 1500 m in open air or 3–5 walls indoors; the 3 V, 2400 mAh battery lasts about 5 years because standby current stays under 35 µA. When pressed it gives an audible and visual signal and sends the alarm over radio, while red, yellow and green indicators distinguish alarm, fault and standby. A choice for heritage buildings, already refurbished premises and temporary spaces; operating range −10 to +55 °C, EMC tested.
