SentexSystems CROWN JEWEL Installation Instructions Manual page 12

•
Whenever the Crown Jewel unit is in use, the Bypass switch must be set to the OPERATE
position.
•
Should the Crown Jewel be disconnected for any reason, the Bypass switch must be set to
BYPASS in order to maintain telephone service to the residence.
•
In multiple unit installations, if you set the unit switches to BYPASS, you must also reset the unit
ID numbers or the unit will malfunction (see Part 5 for information on setting unit ID numbers).
2. Alarm Unit Connections
If the Crown Jewel will be used in conjunction with an alarm unit, it is imperative that the
telephone line connect with the alarm unit first. If the units are not connected in this order,
it will cause sporadic problems with both the alarm and the Crown Jewel unit (see Figure 6).
1. Connect TB3 on the main processor board to the SYSTEM area of the bypass board as
shown in Figures 7 and 8.
2. Connect one set of the 18 to 24 AWG twisted pair telephone wires between the incoming
telephone line and the Alarm unit.
