INSTALL LINEsafe BOX
|1. Drill & 3/16" bit (wood or masonry) for
2. Socket driver for mounting screws.
5. Bag of concrete mix
|Check the position of the network interface box and
the phone line as it enters the structure. Both should
be covered by LINEsafe. In some cases the
network interface box may need to be
Center the LINEsafe box over the network
interface box, mark eight holes, and drill 3/16" pilot
holes for screw mounting.
Note: Drill pilot holes at a slight outward angle. This
will allow easier installation of mounting screws.
Install two top screws. Do not completely tighten the
screws to allow movement for easier conduit
INSTALL LINEsafe CONDUIT
|Remove any clips that fasten the phone line to the
Carefully dig out around the phone line as it exits the
ground. The conduit should encase the phone line
from the phone service box (network interface) to a
depth underground as far as desired. Most phone
lines are buried between 6" and 18" deep.
Measure distance from bottom of the LINEsafe box
to the desired underground depth. Then measure
each piece of conduit from the top adding one (1")
inch for recess into the LINEsafe box.
Cut each piece of conduit and insert the smaller
conduit into the larger and align the slots.
Position the conduit over the phone line and rotate
the inner conduit 180 degrees allowing the tab to
drop into the slot of the outer conduit.
Insert top of conduit into the LINEsafe box. It is
designed to be a tight fit. It may be necessary to
squeeze top of conduit with pliers to slide into box.
SECURING LINEsafe BOX AND
|Install remaining screws in LINEsafe box and
tighten. Mark and drill pilot holes for top conduit
mounting strap, and secure with screws. Position
bottom conduit strap and do the same.
Fill in around bottom of conduit with concrete mix.
INTERFACING WITH ALARM
|Note: By installing LINEsafe, the owner
agrees to provide telephone company access
Only the owner can authorize access
|Recommended: Contact your alarm company for
connection. Some alarm companies may require
notification for add-on accessories.
Pull a single pair (2 conductor) 18-22 gauge phone
wire (concealed) from the alarm controller to the
LINEsafe. Most alarm companies pull extra wire
pairs to the network interface box. If available they
may be used.
Connect this wire pair to the terminal block in the
LINEsafe opposite the sensor wires.
Connect other end to a normally closed zone on
the alarm control panel.
|Auxiliary Instructions for Overhead Drop Installation
|To give the best protection the conduit must
extend from the top of the Linesafe strongbox to
a point at least 12' from the ground. In most
cases this will necessitaite drilling through the
eave and out through the roof, like the electrical
service entrance. If the outside wall of the house
has enough height, extend the conduit to a point
at least 12' from the ground, and install the
service entrance weather head and secure to the
|Additional Tools and Accessories Needed:
2. 1-5/8" hole saw for wood and metal
3. 1/4" to 1/2" drill bit 18"-24" long
4. 10' length of 1-1/4" EMT conduit
5. Plumb line
6. LINEsafe Overhead Installation Kit:
- 10' 4x22 outdoor phone wire
- 1-1/4" service entrance weather head
- 1-1/2" no caulk roof vent flashing
- 1-1/4" EMT compression fitting
- 4, 22 gauge moisture resistant
wire splice connectors
|Disconnect phone line from telephone network
interface and move aside.
Caution: Phone lines do carry low voltage,
sometimes up 70 volts.
|Install LINEsafe box. (See Underground
|Drop plumb line from under eave, centered over
conduit fitting. Mark and drill pilot hole through
eave with 18"-24" bit. Holding drill level along
plumb line, continue out through roof.
|Drill 1-5/8" hole in top of LINEsafe box
approximately 1/2" from back edge and to one
side or the other, being careful not to drill on
top of back switch. Insert compression fitting
and secure with lock ring.
|Slide roof vent flashing over conduit and slip
under shingles. It may be necessary to cut
shingles to fit around rounded top of vent
flashing. Top of conduit may be cut off at this
point to desired working height.
|Using pilot hole as guide, drill 1-5/8" hole up
through eave. From on top of roof, holding drill
plumb, using pilot hole as guide, drill 1-5/8"
hole down through roof. Slide conduit down
through roof and eave into the compression
fitting in top of LINEsafe box.
|Install remaining screws to secure the
LINEsafe box. Tighten compression nut at
base of conduit, and secure conduit to side of
house with straps. Reconnect phone line to
network interface. Refer to Underground
Installation Instructions to connect to alarm
|Unhook phone line strain relief from eave of
house and slide over top of conduit. The strain
relief may need to be repositioned on line.
Insert end of phone line through service
entrance weather head. The weather head has
not been placed on top of conduit at this point.
Using moisture resistant connectors, splice
extra phone line to reach down through conduit
into LINEsafe box. Use electrical tape to
wrap splices securely. The splices should rest
within the conduit protected from weather. Now
install the service entrance weather head on
top of conduit.
