LOGIC & CONFIGURATION (CONTINUED)
The logic equations for F3200 to match Fig 6.2.1 are as follows.
where: OC1 = Gas Initiated LED (i.e. Timer Running)
OC2 = Manual Release Activated LED (i.e. LCS Gas Start)
OC3 = Gas Discharged LED
OC4 = System Inoperative (i.e. any isolate or fault in Gas Control System)
OC5 = Gas Inhibited LED
Zone 1 = Detector Cct 1
Zone 2 = Detector Cct 2
Zone 3 = Gas Start (LCS)
Zone 4 = Gas Released (Pressure Switch)
Zone 5 = Gas Inhibit (LCS)
Zone 6 = Gas Isolated (i.e. Gas Discharge Isolate switch operated, see
note 3)
Zone 7 = Lock-off Valve (if required, see note 9)
Relay 1 = Alert or Evac O/P (1st stage sign FIRE ALARM)
Relay 2 = Evac O/P (2nd stage sign EVACUATE and DO NOT ENTER)
Relay 3 = Gas Release Solenoid
Relay 4 = System Inoperative sign
Isolate = Guard Relay (see note 2)
Timer
T1 [S30:0] = V1 30 Second time delay from "Gas Initiated" (second stage).
Variables
V1 = Z1A . Z2A . ^Z5A + Z3A
Open Collector LEDs
OC1 = V1
OC2 = Z3A
OC3 = Z4A
OC4 = Z5A + Z6A + OC5 + Z7A + Z3:7(1)I + Z1:7(1)F + R1F + R2F + R3F + R4F + R1I+ R2I
+ R3I + R4I + Guard I (see notes 2,9)
OC5 =Z1:2(1)I
Relays
R1 = Z1A + Z2A + Z3A + Z4A (Alert or Evac : Stage 1 or Stage 2)
R2 = Z4A + V1 (Evac Stage 2)
R3 = T1 (Gas Release)
R4 = OC4 (System Inoperative)
ISO (or Rn) = V1 (Guard) (see note 2)
