The Americans with Disabilities Act (ADA) now being enforced, requires a Rescue Assistance System in all newly constructed multi-story commercial buildings and public accommodations to provide a means to request evacuation assistance in the event of an emergency. The ADA also applies to significant renovations or alterations of existing multi-story facilities.
The cost effective solution is the Alpha Communications® / Cornell 4100 series visual Rescue Assistance System, which signals the need for evacuation assistance. The 4100 series provides reliable repeating tone and light signal at the central (master) station. When the alarm is acknowledged, the caller is signaled visually and audibly that help is on the way. When the emergency is resolved, pressing the acknowledge button a second time resets the system. For additional safety, a live 'fault' lamp will signal at the central (master) station, if the wiring has been faulted.
The economical 4100 series is designed to accommodate up to 20 remote locations for each master station. The smallest master station is a 4-unit and the capacities increment in groups of 4 to a maximum of 20. Master and remote stations are made of rugged Stainless Steel and Anodized Aluminum. Master stations emit a loud, clear tone signal that commands an immediate response. When the remote call station is activated, the long-life LED indicator at the master station lights instantly, identtifying
the remote station (zone) in need of assistance. When the master station acknowledges the call, alight and sound informs the caller that the request for assistance has been heard and seen.
When vandalism is a concern, we offer the model 4101/V vandalresistant remote station. The 4101/V features a metal call button and tamper-resistant mounting screws and fits neatly into a two gang electrical box (or plaster ring) and is designed for indoor or outdoor use.
Each master station is powered by a model# PK601A (24VDC) power supply and SS106 transformer. When battery back-up power is required or specified, you may substitute the model# B-5243 in place of the PK601A. The B-5243 power supply contains the back-up batteries and battery charger required or specified.
We also offer a complete line of Rescue Assistance Signage. This includes a series of battery powered room identification signs, as well as direction and location signs. These signs meet ADA specifications for use with Areas of Rescue Assistance. See our specification sheet# APS478 for more information on the signage available.
