Firstly, the Edwards Est 6616-B713 Reverse Polarity Module provides one set of “C” Alarm Contacts, one set of “C” Trouble contacts, a Class B reverse Polarity output, and two 24VDC sources. Also, contacts are rate at 5.0 Amp resistive/2.5 Amp inductive at 28 VDC/120VAC.
In fact, under normal supervisory conditions, a current limited between 2.55mA and 9.9mA DC is supplied at output terminals 1 and 2. An alarm on the fire alarm system will cause the output polarity to reverse. The current remains limited between 2.55mA and 9.9mA DC under an alarm condition. The transmission of an alarm may be inhibit by the Ancillary Disconnect switch located on the Common Control Bin Assembly cover.
In general, Edwards Est 6616-B713 Reverse Polarity Module may be insert into either Bin Assembly as indicated in Chart A. After testing the wiring make connections to the designated terminals as shown in Figure 10B in the datasheet below. In addition, the modular design plus field selectable options allow on-site customizing of the system for specified operating configurations.
