R238 remote control is a wireless expansion module for Honeywell's 238C host, which can be used with 238C for remote arming and disarming and emergency alarms.
The R238 is a wireless extension module for Honeywell's 238C alarm host, providing remote arming, stay, disarming, and emergency alarm functions. It connects the BK, RD, and GR pins of the controller to the C‑, KEY+, and DAIA pins of the host and operates on a 310 MHz‑440 MHz frequency, requiring installation at a central high point away from metal objects.
The guide details how to confirm up to 16 legal remote controllers, delete all confirmed controllers, learn the host password, and describes the four button functions on the remote for arming, stay, disarming, and emergency alarm activation. This manual is written in Chinese.
