Ringer Equivalence Number (REN)
The REN is used to determine the number of devices that may be connected to a telephone line. Excessive
RENs on a telephone line may result in the devices not ringing in response to an incoming call. In most but not
all areas, the sum of RENs should not exceed five (5.0). To be certain of the number of devices that may be
connected to a line, as determined by the total RENs, contact the local telephone company. For products
approved after July 23, 2001, the REN for this product is part of the product identifier that has the format US:
AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point (e.g., 03 is a REN of 0.3).
For earlier products, the REN is separately shown on the label.

Additional Information
Connection to party line service is subject to state tariffs. Contact the state public utility commission, public
service commission or corporation commission for information. Alarm dialing equipment must be able to seize
the telephone line and place a call in an emergency situation. It must be able to do this even if other equipment
(telephone, answering system, computer modem, etc.) already has the telephone line in use. To do so, alarm
dialing equipment must be connected to a properly installed RJ-31X jack that is electrically in series with and
ahead of all other equipment attached to the same telephone line. Proper installation is depicted in the figure
below. If you have any questions concerning these instructions, you should consult your telephone company or
a qualified installer about installing the RJ-31X jack and alarm dialing equipment for you.
