5.4 Input Register
Address Description Values / Unit Remark
3x0001 Copy of discrete inputs 4..1 in least
significant bit
Bit representation:
00=Fire alarm if set
01=service alarm if set
02=External alarm if set
03=Interlock if set
04..15=Not used, read as 0(zero)
Bit
3x0002 Actual test interval, days
0..7, 0 for disabled.
If 7 days, (weekday *8) is added (Sun 0,
Mon 8, Tue 16, Wed 24, Thu 32, Fri 40,
Sat 48)
Example:
If an interval of 168hours on Thursday is
desired the result is :
xxxxxxxxxx100111 = 0x0027 = 39 =
<index for choosed weekday>*8 +
<Testinterval 168H> = 32 + 7 = 39. See
also the remark column and register
4x0003.
Value 0..56 Value representation:
0 = No test
1 = every 24h
2 = every 48h
3 = every 72h
4 = every 96h
5 = every 120h
6 = every 144h
7 = every Sunday
15 = every Monday
23 = every Tuesday
31 = every Wednesday
39 = every Thursday
47 = every Friday
55 = every Saturday

07,06=Damper state,
(00=unknown/moving, 01=open,
10=closed, 11=failure)
11..08=Group belonging, (0=no group,
1-10=A-J 11-15 not used.)
12=Detector enabled if set
13=Damper enabled if set
14 even*= Multibox interlock if set
14 odd**= SOC7-M2 is active if set
15 even*= Fan keeps running during
interlock if set
15 odd**= SOC7-M2 is enabled if set.
Bit/value Note that bit 6,7 is
presented as bits and the
corresponding values for
the 2 bits are :
0=Unknown/moving
1=open
2=closed
3=failure
8-11 is presented as values
for the 4 bits were the value
corresponds to the group
number.
