Electrical Characteristics
Each of the three dry-contact relay switches is rated to support a maximum switching current of 1A@30VDC.
The relay contacts should not directly connected to high current devices such as sirens and flashing lamps.
Central Office Alarm Wiring Example
The following figure depicts how the dry-contact relays can each control up to two external alarm indicators.
In this example, the CO alarm interface is connected to a CO Alarm Panel, where green LEDs are wired to
indicate normal operation, and red LEDs are wired to indicate an alarm condition.
Figure 66: CO Alarm Interface Schematic
With all relays de-energized (normally closed), the green LED is illuminated. If an alarm relay is energized,
the NO (normally open) contact closes and the red LED is illuminated.
