A.5 (Optional) Connecting Linkage Cables Between the
Fire Extinguishing System and Access Controller
After linkage cables are connected between the fire extinguishing system and access
controller, the access controller opens data center doors when the fire extinguishing system
generates an alarm signal.
Fire alarm signals are generated over dry contacts and provided by the specified fire
extinguishing system.
The linkage is valid only when the dry contact over which a fire alarm signal is
generated is ON.
Fire Alarm Signals and the Access Controller
Connect fire alarm signal terminals to terminals A1-2 and GND on the access controller, as
shown in
(using the connection between the fire extinguishing system and
terminals A1 and A2 on the access controller that controls eight doors as an example).
