Figure; Pagefirst Installation - Lightspeed TOPCAT Installation Manual

PAGEFIRST INSTALLATION

The following components are included when the PageFirst option is purchased
as an add-on:
• PageFirst sensor clip with wire pigtail (PFSC)
• 50' length of wire with connector
• 2 wire nuts
Step 1: Locate paging speaker and sensor clip
If possible, the paging sensor should be hung around the 8-ohm lead wires
that are connected directly to the speaker. If it is a sealed ceiling speaker
where only the 70-volt wire is accessible, connect to the exposed 70-volt wires.
a. Locate the paging speaker in the classroom. NOTE: PageFirst does not
work with telephone intercom systems.
b. Locate the PageFirst sensor clip. This clip is designed to hang around the
wire connected to the paging speaker. Through induction, it detects the
audio signal as it comes through the wire.

Step 2: Connecting the sensor to the
speaker wire
a. Gain access to the back of the
speaker either up in the ceiling
or on the wall. NOTE: there is no
need to disconnect any wires.
b. Unclip and open the top loop
of the PageFirst sensor. Hang
it around one of the lead wires
connected to the paging
speaker and clip it back together

(Figure 1).

Step 3: Connecting the PageFirst sensor to the TOPCAT
The sensor needs to be hard-wired back to the TOPCAT.
a. Insert the euro-block connector of the wire into the PageFirst input jack on
the Lightspeed system. Secure with a screw driver by tightening the screw
on the left and right sides of the terminals. (Figure 2.3)
b. Route the wire from the TOPCAT to the paging speaker. NOTE: when
routing wire make sure to secure to the building structure, as electrical and
building codes require.
c. Connect the pigtail of the sensor clip to the length of wire, using the
provided wire nuts. Coil and secure excess wire as needed. NOTE: wire can
be cut and stripped to the appropriate length if necessary.
Step 4: Testing PageFirst
A page will need to be broadcast through the system to verify PageFirst is
properly sensing the audio signal.
a. Turn on the system and begin speaking.
b. Broadcast a page through the central paging system.
c. The system should mute as the page is broadcast. When the broadcast is
over, the system should amplify the mic as normal.
d. While walking around the room, continue talking into the microphone.
Verify that the system is not muting during times there is no page being
broadcast.
Step 5: Adjusting the Sensitivity
a. The sensitivity adjustment (labeled "ADJ") is pre-set to the 12 o'clock
position with a detent. This should be the appropriate setting for the
majority of installations.
b. If the system does not mute while the page is being broadcast, turn the
sensitivity adjustment up by turning the ADJ knob clockwise and test again.
c. If the system mutes during times when a page is not being broadcast, turn
the sensitivity down by turning the ADJ knob counterclockwise, and test
again.
