Assembling a BIP external alarm cable
Assemble a BIP external alarm cable to connect the BIP to a customer
premises external alarm indicator.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• To connect the external alarms, you must provide the cables with D-sub
connectors with the appropriate number of male or female wired pins
ready to be plugged in. In preparation for assembling the cable, do the
following:
— identify which BIP connector you are replacing to a CPE alarm; for
the types of alarms and their purposes, refer to 241-1501-200
Passport 15000, 20000 Hardware Description
— locate the table in “Procedure job aid” (page 238) that corresponds
to the BIP connector so that you can identify the orientation and type
of connector to be used on the cable
— get the appropriate connector for the BIP connection
— measure the path between the alarm cable endpoints and match the
gauge of wire to use; 22 or 24 AWG wire is typical, however, the
gauge of wire can vary according to local electrical codes, the
distance between endpoints, and the amount of power required to
operate whichever terminal device is to be used (for example, a lamp
or a LED).
Procedure steps
1 Refer to the site’s record of alarm connections to verify where the
endpoints occur. Locate the endpoints of the alarm cable between the BIP
connector at the rear of the BIP and the CPE connection.
2 Measure the distance between the endpoints and match the gauge of
wire to be soldered to the connector pins.
3 Strip the wire and solder it to the connector using prescribed methods for
the type of connector.
4 Repeat step 3 for each additional wire for the BIP connector assembly.
You may need to refer to the pinout tables in “Procedure job aid”
