7. Enable supervision on Relay 2 (Evacuate Relay) and use the following logic in the
programming.
Relay 1 (Alert) : Supervision enabled, Latching, MAF mapped.
Relay 2 (Evac) : Supervision enabled, Latching, MAF mapped.
Relay 1 = Z1A + Z2A + Z3A + Z4A
Relay 2 = Z4A + V1
V1 = Z1A . Z2A . ^Z5A + Z3A
Where:
Z1 = Detection circuit 1
Z2 = Detection circuit 2
Z3 = Gas Start (LGCS)
Z4 = Gas Released (Pressure Switch)
Z5 = Gas Inhibited
Program the panel as otherwise described in Section 6.2.2.
