PRODUCT DESCRIPTION LCU3
LCU3 provides all of the features described on pages 3-4. Please read these
pages first.
Model LCU3 has the additional ability of being able to Answer an Incoming
call on a telephone line, after a user selectable number of rings (0-20 rings).
Setting 0 Rings, disable the Auto Answer facility.
The Default setting is that LCU3 will Answer incoming calls after 2 rings.
After Answering a telephone call, LCU3 will ‘listen’ for DTMF Commands. If
a programmed command is detected, LCU3 will close one or both of its
Internal relays, depending on User Programming, exactly the same as LCU1
and LCU2.
Our LCU1 and LCU2 models do not answer calls. They respond to DTMF
commands made during an outgoing call, or an incoming call answered by
another device on the line, such as LCU3, Answering Machine or other
suitable answering device.
Multiple LCU1 and LCU2 units can be used with LCU3 to provide for Basic
Access Control, Lift Control or the Powering ON, OFF or RESET of One or
More Electrical devices.
