Emergency Notification Siren System*
Hidden Valley Lake Association has completed the
installation of a community-wide outdoor Emergency Notification Siren System,
(ENSS). The System will be used to warn members, tenants, and guests of an imminent
catastrophic event, man made or natural. ENSS consists of six sirens,
strategically placed within the subdivision. Although the sirens will be
loudest within the Hidden Valley Lake subdivision, neighbors in close proximity
will be able to hear them.
It is possible that in some cases residents may not
hear the sirens. Therefore, it is incumbent upon all residents to make
arrangements to receive Nixle alerts. Nixle alerts will provide the nature of
the emergency and the suggested actions. Cellphone users, please text HVLAlert
to 333111 to receive alerts and reverse messaging information. For landline
phone users, please register at hvla.com or Member Services to receive email or
All residents and affected surrounding area areadvised that the Hidden Valley Lake Association will conduct monthly testing of the Emergency
Notification Siren System.
Monthlytesting will occur on the 1st Saturday of every month at 12 Noon.
The purpose of monthly testing is to ensure that
the sirens are functioning effectively and to increase awareness of the
importance of personal emergency preparedness.
Siren testing will sound for 30 seconds and begin
with a low tone ramping up to much higher tone before tapering back to low.
That will conclude the testing. Please visit www.hvla.com to become familiar with our siren tones*. For
testing purposes, the choice of the 30 second tone is distinctive and very
different than that of the emergency tone. When
the system is activated for a test, no action is necessary.
In the event of a real emergency such as a wildland
fire, the sirens will emit a wailing tone, low ramping to high, holding for 10
seconds, then tapering to low, followed with two cycles of low to high, but
holding for just 3 seconds then tapering to low. This will continue for three
minutes. Hidden Valley Lake Association will issue a Nixle alert for
the threat information when the emergency tone is used and provided access to
Nixle communication methods are still available.
When activated, the siren will sound for three
minutes. Should you hear the emergency alert tone, you should take the
