The ETB Switch Assembly is optional.
The ETB switch is installed in the safety string in series with the Buffer switch.
Figure 106: Emergency Tape Break Switch in Series with Buffer Switch
There is slack in the wire when the tape tension spring is fully extended. This slack allows for
tape and/or building movement. If the tape breaks, the tension spring retracts and pulls the
cable attachment out of the ETB switch, opening the safety string. Verify that the cable length
allows the tab to pull out of the ETB switch when the spring is retracted. See Figure 108.
