NOTES:

1.Connect EOL Diode assembly IN SERIES as shown with Solenoid on output #3 (Release Solenoid) and output #4 (Release Solenoid). Black wire to positive terminal on panel and Red wire through Solenoid to negative terminal on panel.

2.Polarity is shown on indicating circuits in normal (no alarm) condition. Polarity reverses when ouptut is activated.

3.Leave EOLR (provided) on all unnused circuits.

4.See the instruction manual for circuit information, panel limits, and battery sizing.

5.For wire routing instructions through the releasing panel, see Note 3 on page 56 of the instruction manual.

6.See instruction manual for proper programming.

7.See instruction manual for list of compatible smoke detectors.

8.See specific system type data page for proper pressure switch settings.

9.Loss of DC power below 20 volt causes output #3 (Release Solenoid) and output #4 (N/O Solenoid) to drop out.
