3.5 Connecting External Alarms/Control (Optional) (Continued)
Figure 3-7. Electrical Specifications for Inputs and Outputs
The system designer should have identified any external alarms and controls to be
connected. Make external alarm/control connections as follows:
1. Identify the input/output connection to be used for each external alarm/control that
is to be installed. Figure 3-8 shows a typical wiring diagram for external alarm
input.
2. Make connections using a compatible DB15 male connector (not supplied).
