Doing a 360°
Early Warning Signals (EWS) sirens from Edwards Signaling & Security Systems project a clear and powerful decibel level in all directions simultaneously. This 360§ omni-directional advantage means that emergency warnings are communicated without a distorting peaking-and-ebbing effect. The Series ranges from the single-tone compact EWS-V1 models, rated at 107 dB, for large industrial facilities or small communities, to the single-tone EWS-V3 units featuring projectors in an 8-horn, equal length, single-row configuration, rated at 112 and 118 dB, for warning over long distances. Dual-tone models range from the EWS-V4 Series, rated at 115 dB, to the 125 dB EWS-V8-3, the largest omni-directional siren in existence. Decibel ratings for wide area signals are calculated at 100 ft. or 30.5 m. For more information, visit: www.edwards- signals.com.

A Very Smart Knight
Silent Knight offers industry-wide compatible fire alarm solutions for small to mid-size institutions and commercial sites with its IntelliKnight Series. The IntelliKnight line of products features three control panels - the 5700 for smaller applications, the 5808 for medium size applications, and the 5820XL for larger applications. Each of these innovative fire systems deliver state of the art capabilities in a cost-effective package.

No twisted or shielded cable is required to install any of the products in the IntelliKnight line. Standard wiring helps reduce installation costs on new installations and greatly speeds up retrofit jobs where cable has already been run for an existing system. This enables users to upgrade an older conventional fire system for less money.

All products in the IntelliKnight series feature drift compensation to maintain detector sensitivity at the proper level and reduce the occurrence of false alarms due to dirty, dust-contaminated smoke detectors. With drift compensation, the products can pinpoint detectors that are approaching the limits of normal operation before a false alarm occurs by alerting the user of the problematic detector with pinpoint addressable accuracy. The alert is sent on-site via a trouble indication, or remotely via the built in digital communicator. For more information, visit www.silentknight.com.
