ZONE TYPES cont.
FOLWR1: This normally closed zone type is used to provide protection along the exit and entry
path(s) between the control panel or the remote keypad and the exit and entry door(s). When area
1 is armed, this type of zone is instant acting except for the following two cases: During exit, no
alarm will occur on any FOLWR1 zone within the exit time allowed and, similarly, during entry,
no alarm will occur within the entry time allowed (see Exit-1 Time variable, page 48). After the
delay time expires, the FOLWR1 zone responds as an instant-acting AREA-1 zone. Straying from
the follower path into other protected zones during the exit/entry time will also cause
instant-acting alarms.
FOLWR2: This normally closed zone type is used to provide protection along the exit and entry
path(s) between the control panel or the remote keypad and the exit and entry door(s). When
area 2 is armed, this type of zone is instant acting except for the following two cases: During exit,
no alarm will occur on any FOLWR2 zone within the exit time allowed, and similarly, during
entry, no alarm will occur within the entry time allowed (see Exit-2 Time variable, page 48). After
the delay time expires, the FOLWR2 zone responds as an instant-acting AREA-2 zone. Straying
from the follower path into other protected zones during the exit/entry time will also cause
instant-acting alarms.
GATE: This normally closed zone type is used to monitor the gate valve or the post indicator
valve (PIV) in a sprinkler system. When a gate valve closes (i.e., the switch contacts open), GATE
VALVE output C-LEM 16 will operate and the event will be logged. If the Alert & Display
variable (see page 49) is set to one (1) for an attended site, then the piezo-sounder will beep and
the display will show the flashing alert message *SPRINKLER SUPERVY* , alternating with
the warning message ++CALL SERVICE++ and a flashing zone description.
L During service to the sprinkler riser, the gate valve switch may have to be operated a number of
times in succession. To avoid unnecessary traffic to the central/monitoring station, a Supvry
Shutdown variable (see page 50) may be programmed to limit the number of signals.
PRESR: This normally closed zone type is used to monitor the pressure switch on a sprinkler
riser. When a pressure drop occurs, PRESSURE output C-LEM 17 will operate and the event will
be logged. If the Alert & Display variable (see page 49) is set to one (1) for an attended site,
then the piezo-sounder will beep and the display will show the flashing alert message
*SPRINKLER SUPERVY* , alternating with the non-flashing warning message ++CALL
SERVICE++ and a flashing zone description. In the course of servicing the sprinkler riser, the
pressure switch may have to be operated a number of times in succession. To avoid unnecessary
traffic to the monitoring station a Supvry Shutdown variable (see page 50) may be programmed to
limit the number of signals.
FLOW: This normally open zone type is used to monitor the normally open flow switch on a
sprinkler riser. Contact closure causes the retard timer (see Retard Time variable, page 49) to
count down. If the switch contact is still closed at the expiry of the retard time, the panel will
execute the FIRENO routine (see page 33). If the switch opens before the timer finishes counting
down, the retard timer will reset and no further action will occur.
