New Low Frequency Notification Sounders and
Backup Amplifier Offer Easy Solutions to Meet Code Requirements and Engineer
NORTHFORD, Conn., Jul. 27, 2015 – Honeywell (NYSE: HON) today announced it has introduced
Silent Knight® low frequency sounders and sounder bases, plus a
unique amplifier to provide code-mandated backup power capabilities for
emergency communication systems.
To satisfy specifiers’ demand for more secure fire
and emergency voice communications, a unique amplifier has been developed by
the Silent Knight team to provide backup power capabilities for the IntelliKnight 5820XL-EVS emergency voice system.
The new line of low frequency notification solutions includes
SpectrAlert® Advance low frequency
sounders and sounder bases. The sounders and sounder bases are designed by
System Sensor to emit a 520 Hz tone, which studies have found more
effective at waking building occupants, including those with mild to severe
hearing loss. The expanded line includes speakers and speaker/strobes, as well
as sounder bases compatible with Silent Knight smoke, heat, and fire/carbon monoxide (CO) detectors.
appliances provide the low frequency output to meet current NFPA 72 standards and International
Building/Fire Code. Existing installations of current Silent
Knight detectors and traditional sounder bases can be easily upgraded by
replacing the base with the new low frequency version. In applications where
speakers are being used for low frequency notification, the IntelliKnight
5820XL-EVS has also been updated to emit the 520 Hz tone.
Back-up power is an essential component to meeting
fire alarm voice evacuation and emergency communication systems survivability
requirements. The new EVS-100W can deliver 50 watts of power to
the 5820XL-EVS, plus 50 watts of back-up power. For more audio power, the
Silent Knight EVS-100WBU can be used for 100 watts of power with 50 watts for
“Survivability is a code-required function of fire
and voice evac systems, and we’re seeing more specs calling for more power to
back-up these systems,” said David Pakech, sales leader, Silent Knight-IntelliKnight.
“These voice systems are getting bigger and wall space is at a premium, so the
backup amp will soon be a commodity for most jobs.”
