Emergency Lights, Self-Testing, Dual Circuit Products (2 items)

An emergency light is a lighting device with a battery backup that switches on automatically when a building experiences a power outage. Emergency lights are standard in commercial and high occupancy residential buildings, such as college dormitories. Most building codes require emergency lighting be installed in older buildings as well.

This feature may be added to many exit sign and emergency light fixtures, the SDT feature prolongs battery life, and reduced man hours required OSHA tests. Self testing diagnostic automatically executes a 15 minute test every 30 days and runs a 90 minutes test once per year. The major reasons batteries typically fail is because they remain dormant for long periods of time. With the SDT feature automatically simulates a full discharge and full recharge to keep the batteries in peak performance. If any problems arise during this testing process it will report them through the user interface. This benefit drastically reduces man hours required by OSHA to manually perform the tests.

Dual circuit exit signs. These unit allows the fixture to have dual power feeds. The idea behind this is so that when on normal power, the fixture is fed from a switch leg and can be turned off by the occupant. The PTS relay coil is fed by unswitched normal power. The normal power from the switch leg is connected to the normally open contacts on the PTS relay.
