The 4500 Alarm module can control up to four remotely controlled devices,
such as air conditioning, heating, lighting, and so on, through four relays.
The relays are controlled through the Control Outputs panel on the Alarm
Module Configuration window.
The Control Output relays have Form 1-C contacts (normally open (NO),
normally closed (NC), and common (COM)) that are accessible through the
STATUS/CONTROL connector (see Figure 2-6). The contact configuration
allows flexibility in connecting the module to remotely controlled devices.
Control Output relays 1, 2, and 3 are normally in an off state (COM and NC
contacts closed) when no command is sent. They are energized (changed
from a normal off state to an on state) only when a control command is sent.
Control Output relay 4 is normally energized (COM and NO contacts closed)
when no command is sent. When a control command is sent, the relay is not
energized causing the COM and NC contacts to close and in turn causing the
external device to be activated or deactivated.

Figure 2-6. Control Output Relay Configuration
Figure 2-7 shows how the module activates a Control Output relay to acti-
vate the supplemental air conditioning. The command maintains the contact
closure for 30 seconds, which means the remote device must have the capa-
bility of sustaining itself until the situation resolves itself, such as when the
air temperature returns to normal.
