4 Releasing Application
WARNING: For releasing applications, we recommend that circuit 7 and 8 are not utilized
for AUX power or NAC circuits. Only to be utilized as input circuits.
NOTE: For Releasing Applications, the minimum battery size that can be used is 18 Ah
(BP-61)
NOTE: Refer to the Solenoid Compatibility List, Document ID A6V11620059.
NAC 5 and NAC 6 can be configured for releasing. Below is a list of approved solenoids
and only these solenoids can be used on the circuits. NAC 5 will be considered ZONE 1
Class B and NAC 6 will be considered ZONE 2 Class B. When Class A is required, both
ZONE 1 and ZONE 2 will be required.
Two switches (S600 and S601) enable or disable releasing on NAC 5 and NAC 6. S600
controls releasing on NAC 5 (RELEASING ZONE 1) and S601 controls releasing on NAC
6 (RELEASING ZONE 2). In order to configure the outputs for releasing, the switches
must be in the EN position. Configuration of releasing, including Class A and B, is done
via the configuration tool. If the switches are in positions not matching Zeus, then a trou-
ble will post on the Operator Interface.

Figure 6: Releasing Enable/Disable and Disconnect switch
To configure NAC 5 for releasing Class B, RELEASING1 needs to be in the EN position.
If no releasing is desired on NAC 6, then RELEASING2 is in the DIS position. If Class A
releasing is required, or two Class B circuits, then both RELEASING1 and RELEASING2 are
in the EN position.
Below the configuration switches is the Releasing Disconnect Switch. This can be used to
disable power to both Releasing Circuits, to guarantee that the solenoids are not accidently
tripped during servicing. The panel will post a Supervisory event, indicating the Releasing
Circuit is in the off normal state. Also the LED below the disconnect switch will be ON when-
ever the power to the releasing circuits is disconnected.
