BEFORE YOU INSTALL AND OPERATE THE EQUIPMENT
— Prohibitions and precautions —
* Operation i Fig. 1
1. On all LAP master stations, except station initiating a call, OFF button MUST
BE DEPRESSED and LOCKED DOWN, or system will not work. The illuminated
LED above OFF button indicates you forgot to depress OFF button, if not in
use. (See Fig. 1)
2. The illuminated OCCUPIED LED indicates the other station is using the system.
While this OCCUPIED LED is lit, (See Fig. 2)
(1) Do not depress any selector button, or an electronic feedback will occur at
initiating and receiving stations.
So, when you receive calls from another master and a sub at the same time. Fig. 2
REPLY FIRST TO THE MASTER and, after the OCCUPIED LED goes
out, depress selector button of the calling sub and communicate.
(2) Can not make All Call announcement.
3. When a sub station calls during Background music distribution, the call tone
will come out through all LAF station speakers, and call-in annunciator LED
stays lit for approximately 20 seconds on the called master station.
* Installation;
1. DO NOT CONNECT ANY TERMINAL ON ANY UNIT TO AC POWER LINES.
2. Maintain at least 50 cm (20") distance from any AC wiring. Shielded cable
should be used to reduce the possibility of AC inductance.
3. Be sure not to plug power supply into AC receptacle until you complete wiring
connections, and unplug before opening it.
4. Lay out your system in advance. Determine the exact location of each station.
-Assign station number and make a sketch showing the number of wires and
color codes from one station to another. Begin your installation with master
station No. 1. Upon installing second master station, we recommend a test be
made for all functions, calling and talking between each station.
After connecting and testing all the masters, begin sub station installation.
5. Insulate by tape, etc. each unused connector wire end. If connector wire end
touches the other wires or back box it will cause damage to the units.
Installation location;
6. Select the installation locations that would not be exposed to temperature/
humidity extremes, water, oil, dust, iron dust, inflammable and chemical
products, etc.
7. To avoid feedback, DO NOT PLACE MASTER STATION AND ANOTHER
MASTER OR SUB STATIONS BACK TO BACK, OR ON A COMMON WALL
BETWEEN ROOMS. (See Fig. 4)
Unit selection;
8. When making an intermixed system, note in advance that master stations;
LAF-3A, LAF-5, LAF-10 console type have no button for All Call nor door
release. LAF-IB and LAF-3B have only door release button. If such functions
are required at console type station, please use LAF-1 OS.
9. If any LAF-B station: LAF-1B/3B/7B/10B (Type A) is intermixed with existing Fig. 5
models: LAF-3A/5/10/10S/10B, install a supplied shorting chip on back of all
the LAF-B units. (See Fig. 5)
Adaptor installation location
10. Locate PS-12A (or PS-1 2C) power supply near center of the system.
* Maintenance
1. Clean your equipment with a soft cloth dampened with neutral
household cleanser. Never use thinner or benzine, etc.
