Regional Regulatory Requirements and Notices
UL Applications
Open Area Applications: Covers the applications where the nuisance alarm sources such as cooking are
l
expected. Under UL268 7th edition compliance under Open Area Applications, a detector is not permitted to
signal an alarm under UL defined nuisance alarm fire conditions.
Special Applications: Covers the applications where very early warning is paramount and nuisance alarm
l
sources such as cooking are not expected. Under UL268 7th edition compliance under Special Applications, a
detector is permitted to set to higher sensitivity and Open Area Applications limitations do not apply.
Use of Software Tools (ASPIRE and VSC / VSM4)
Simplex uses ASPIRE pipe modelling software tool from Xtralis to analyse pipework designs to achieve UL
compliance. For UL applications explained above, ASPIRE software is required to design sampling pipe networks
that conform to the performance claims verified by UL and listed in Table 1 below. Each sample hole is reported
with a transport time and a sensitivity in ASPIRE. Referring to the Table 1 below, for UL 268 7th edition compliance
the pipework design shall ensure that the:
Transport time for each sampling hole is less than the applicable maximum transport time.
l
Sensitivity of each sampling hole is within the applicable minimum and maximum hole sensitivity.
l
Simplex uses VSC / VSM4 configuration / monitoring tools from Xtralis to configure / monitor detectors. For UL 268
7th edition compliance, all detectors are factory shipped in Open Area Applications configuration. For continuous
compliance under UL 268 7th edition, ensure that under detector Smoke Thresholds configuration screen on VSC /
VSM4:
The correct UL7 Mode option is selected under the required application. Only Special Applications mode
l
permits higher sensitivities and used where cooking will not occur.
The detector fire alarm threshold settings generated with ASPIRE must be applied to the detector configuration
l
under Alarm Levels. The fire threshold alarm level that initiates an evacuation signal must be set such that the
Hole Sensitivity remains within the allowed range as shown in Table 1 below.
