SUMMING (NON-LISTED)
The CyberCat photo, photo/heat, photo/duct and ion detectors are capable of providing an accumulating
percentage for groups of up to eight devices. This accumulating percentage can activate an alarm from the
same types
of devices where there may not possibly be enough obscuration to cause an individual detector
to initiate an alarm condition. This operation can be very beneficial to detect a fire early. As a fire builds, the
smoke will rise and typically accumulate in several detectors. It typically takes longer for an individual
detector to reach the alarm level. If several detectors are rising in obscuration detected, the alarm can be
detected faster and notification can be accomplished in a prompt manner.
SUMMING EXAMPLE:
Photo Detector SUMMER, Loop 1 - address 5. This device is configured to Sum the following devices which are
physically located near one another in the hazard: Loop 1, addresses 10,11,12,13,14,15,16, and 17. It is
programmed for a Summing threshold of 4%/ft. Each Summee (addresses noted previous) is configured for the
obscuration to be transmitted to the Summer at 0.5%/ft, 0.6%/ft, 0.7%/ft (up to 8 levels). When the Summer obtains
a SUM of the obscurations that are >= 4%/ft it reports the event to the system.
Note:
As the obscuration level of the summee rises and falls, it will broadcast an “Analog Value” event
message in relation to the summing functionality. The Summer will look at the most current values sent from
the Summee to calculate the SUM for the SUMMING ALARM.
To set up this operation, a single detector is selected as a SUMMER. The Summer can look at information from 8
photo (or ion,
same type
as summer and
same loop
as summer - can include the summer) detectors called the
SUMMEE(s). The Summer will total the obscuration percentages received from each summee defined. The
Summer can be set to alarm from 1-10%/ft (programmable in 0.5%/ft. increments). Each Summee has
configuration settings for defining the level of obscuration to be transmitted to the summer (0.5 – 4%/ft in 0.1%/ft
increments). Summing groups can overlap and there is no limitation on the number of Summers. The Summer can
be configured to report as any one of the following system event types when activated: Alarm, Summing Alarm,
Supervisory Latching, Supervisory Non-Latching, Pre-Alarm1, and Pre-Alarm 2.
3.4.8
SMOLDER (NON LISTED)
The Ionization detector provides a smolder enhancement feature that allows the sensitivity of the detector to
be increased where there is a slow buildup of smoke. If the device senses an increase in obscuration of
approximately 30% of alarm, it will speed up its alarm response calculations.
3.4.9
WALK-TEST
Walk-testing allows for the system detectors (i.e., photo, photo/heat, photo/duct and ion) to be tested for
proper operation without unneeded disturbance to building occupants. By default, all detectors are configured
to participate in a system walk-test using smoke. Detector configuration can be changed using the panel’s
programming software C-Linx to allow walk-testing using Fike’s IR tool. The IR tool or optional Remote Test
Station must be used for duct detector walk-testing. Detectors may only be activated once during the walk-
test mode. Refer to Section 6.4.1.4 for further details.
