24-Hour Types
Description
A
Trouble Zone
Produces a trouble condition on zone with an option for a pulsing keypad sounder.
B
Alarm Zone
Activates burg bell on any faulted condition. If zone is not normal after the alarm memory
is cleared, the alarm is converted to a trouble display.
C
Alarm/Trouble
24-hour zone that causes an alarm with the burg bell on a short and a trouble condition on
an open. Must be EOL to derive trouble condition. Dialer sends zone alarm code for short
and trouble code for open. If zone is not normal after the alarm memory is cleared, the
alarm is converted to a trouble display.
E
Fire, No
Verification
Fire zone that works like a 24-hour alarm/trouble zone but uses the fire bell. Note that this
must be EOL zone. This zone type is usually used for a switched input such as a pull
station.
F
Fire, With
Verification
Intended for a 4-wire smoke detector connected to the smoke power terminals. A short
produces a temporal fire bell and an open produces a zone trouble. Must be EOL to
derive the trouble condition.
Verification process: Verification will not occur if any fire zone in the system is already in
alarm. Upon detection of a short, power is removed from the smoke detector power
terminals for 8 seconds. After restoring power, the system waits another 4 seconds, then
tests the zone again. If a short still exists, an alarm occurs.
Fire Trouble: Fire trouble occurs in 2 different ways. The first way is for the loop to open.
The second way is if the loop is still shorted after a fire alarm has been silenced and the
user clears alarm memory. The alarm is changed to a trouble. No trouble is reported to
the CS at this time (serves as a reminder to let the end user know the zone is not active).
On clearing alarm memory, if a fire verification zone is still shorted the verification process
is repeated about every 4 minutes to try to reset the smoke detector. A tamper on a fire
zone results in a trouble, not an alarm.

Hardwire Loop Type – If this is a normal hardwire zone, select the
type of loop. This selection is not applicable for double-balanced, fast, or
zone-doubling zones. For EOL, use a 2.2k loop resistor.

Silent – If selected, alarms will be sent to the central station but no
sounding (bell, keypad sounder) will occur.
Swinger – If selected, this zone will stop reporting alarms during a
single armed period if the number of alarms within that armed period
exceeds the number set in Submode 1, Question 10, Location 4.
NOTE: Swinger should only be used for controlled type zones and must
not be used for 24-hour type zones.
UL
Swinger option must be disabled for UL installations.
