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. 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. The REN of an alarm system is part of the product identifier that

Note: For whole house line seizure with DSL service present on the phone line, you must install
a filter. It is suggested to use the DSL alarm filter model Z-A431PJ31X manufactured by
Excelsus Technologies, or equivalent. This filter simply plugs into the RJ-31X jack and allows
alarm reporting without breaking the internet connection.
