The Dinsafer Helio DKPH4 is a wireless two-way RFID keypad designed as an accessory for the Helio smart alarm system. It communicates bidirectionally with the main panel — sending arm, disarm, and home-arm commands as well as receiving status feedback from the panel.

The keypad supports 125 kHz RFID tags with no limit on the number of registered tags. A built-in 800 mAh rechargeable lithium battery provides up to six months of standby time under typical daily use. Password control and a tamper alarm function protect against unauthorised access.
