Sensor Connector Ratings
Voltage: 9-11.2 VDC
Current: 2 Amps max through single relay connector (2 Amps max total across 4 connectors.
CAUTION
When utilizing ‘Wet’ contacts, the maximum power that can be drawn by the
annunciators is 2A.
The SmartWireless® CX is also available with ‘Dry’ relay contacts (Figure 7). Dry relay Contacts allow
the user to control annunciators that operate off an exterior power source that relies on the controller to
provide only contact closure to apply voltage to the annunciator. The relays are rated for 120-220 VAC/24
VDC, 2 A max. It is important to note that the ‘Dry’ contact feature utilizes a common return for all
annunciators.
