Who can benefit from using an Intelligent Switching Device?
Institutional and commercial facilities that use an Emergency Power Generator to provide Emergency Power for Elevators, HVAC and Emergency Lighting.

What are the advantages of using an Emergency Generator and the BLTC-I OR R?
The requirement to leave Emergency Designated Light Fixtures on 24hours/365 days a year is eliminated, thereby saving energy and maintenance expense. Also a higher and better safe light level is obtained in more areas than is strictly required by Life Safety code.

What is the purpose of the BLTC-I and BLTC-R?
In an ever changing environment to save money and energy, the BLTC-I&R, via the Room light switch,cause the Emergency fixture to act like a Normal fixture. If Normal power is interrupted, it will failsafe to normally closed, mechanically latched Emergency Power contacts. This insures Emergency Fixture illumination when generator comes on line.

Does the BLTC-I and BLTC-R have a UL924 listing?
Yes! File #E206507.

Does the BLTC-I and BLTC-R have any other special features?
Both units come equipped with a Test Switch as posted in Underwriters Lab Book under Emergency Lighting and Power Equipment-UL924 page 44 dated May 21, 1998. Under heading 29 TEST SWITCH, Paragraph 29.1 Test switch required effective June 1, 2001.
In addition to Test Switch, 3 LED’s are part of the test and status conditions of both the Normal and Emergency circuits the BLTC’s are in. The Test Switch gives instant check of Emergency Fixture and the LED’s give instant Visual status of Normal and Emergency circuits.

Will it require a retrofit?
Any place where you now have Emergency Ballast fixtures you can insert a BLTC-R in line using a 411/16 box or place a BLTC-I directly in the Ballast channel of the Emergency fixture.

What type of switch can you use with the BLTC-I and BLTC-R?
Since the BLTC-I and R are to override switches in the case of Emergency per UL924, you can use Room switches, Photo cells, Time clocks and any other type of switch that can supply BLTC-I and R switch line, with Light branch voltage

Why is the BLTC called Ballast Load Transfer Control?
Our first BLTC’s that were marketed in Jan., 1999 to June, 2000 did transfer the load from normal to emergency power. Due to too many variables in the field we developed a much simpler BLTC-I and R, using 6 wires and shunt switching the emergency power. The end result: less mistakes in hookup. Room shares light loads to normal and emergency power distribution panels. This also allows constant monitoring of the emergency system. In the process we have never had a BLTC-I or R NOT failsafe to emergency power

What are the electrical requirements?
Both units can be ordered in either 120 volt or 277 volt. Units have surge suppression up to 50,000 volts and have been tested by UL to withstand 10 direct shorts with no adverse effect to units. BLTC-I and BLTR both have 30AMP relays, which gives them their 10AMP UL rating for emergency load.

Is there a warranty?
Nine 24, Inc. was started in 1998 when a need for a UL 924 product BLTC became apparent to its owner who has been in the lighting business for over 25 years and who had been using this concept by putting together components to accomplish what the BLTC¹s do.
