CKNU Network Communication Module connects the C&K23XX series alarm hosts or IR access control system and transmitting the information via network between the alarm center and the hosts. The module can be installed in the box of the C&K Alarm Host or in other control box. Power supplied by host and transmission by network will greatly increase the transmission speed for the transmission of arm, disarm, bypass remove bypass or alarm information at real time, also, the center can control the hosts such as arm, disarm, bypass, remove bypass, host reset, clear alarm memory and so on. Remote transmission speed is 20-30 times as the former speed. Build-in clock chip will accurately record the time when event taking place. CKNU Network Communication Module
