Figure 8 6-pin External Alarm Connector for ‘Wet’ Alarm Contacts
The Smart Wireless® CXT is also available with ‘Dry’ relay contacts (Figure 9). 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 ‘dry’ relays are rated for 120-
220VAC/24VDC, 2A max. It is important to note that the ‘Dry’ contact feature utilizes a common return
for all annunciators.
