Alarms
Alarm signals from external sensors are received by an ALI or RCI which forwards them to the CU.
The RCI is used if the WRH has an RCU, otherwise the ALI is used. The software on the CU can
activate acoustic or visual alarms or direct the alarm to the P33 alarm port for forwarding via an RCU
to an OM-Online or OMS workstation. Alarms can also be handled by the FON. Alarms can be
configured from an OM-Online or OMS workstation.
External Alarm
Burglary, fire or other external alarms can be handled by the WRH. External alarm sensors and alarm
signals are connected to the P33 alarm port located to the left in the cabinet, as illustrated in Figure 3-
8. The P33 alarm port is described in Chapter 2. The cable for this installation is taken through a
strain relief bushing at the bottom of the WRH cabinet.
Door Open Alarm
A door open alarm can be configured and installed in the WRH. This is arranged with a door switch
connected to P28, as illustrated in Figure 3-8.
