If the Smart Wireless® CXT is ordered with the Relay PCA option, the Relay PCA can be configured to
provide either ‘Wet’ or ‘Dry’ contacts for external annunciator activation.
The ‘Wet’ contact option
provides a nominal 11V Battery Power to external annunciators when an alarm is initiated. These wet relay
outputs are rated for 9-11.1 VDC, 2A max total (A1, A2, A3, and FLT outputs combined). The ‘Wet’
contacts are available on a 5 pin (Figure 7) or 6-pin (Figure 8) Alarm Connector. These outputs are
specifically meant for external 12V annunciators such as the external A1 C1D2 Horn or four-strobe/two-
strobe alarm bar, which is designed to operate on the unit’s 12V Battery.
The 6-pin Alarm connector is intended for use with the Detcon Four-Strobe or Two-Strobe Alarm Bar. The
Two-Strobe Alarm Bar has strobes that are activated when alarm 1 or alarm 2 are active on the CXT
controller. The Four Strobe alarm bar has strobes that can be configured to activate individually when a
specific sensor is in alarm (See Section 5.3.2 for configuration information).
