manual abstract


A call from a door station can only be answered by a master station. SPECIFICATIONS: Power Source: 12V DC at master. Use one PS-1225UL per system, or one PS-1225UL per BG-10C when All Call is included. Communication Output: 800mW at 20 ohms (receive); 500mW at 20 ohms (transmit) Communication: Push-to-talk, release-to-listen (TALK button), or VOX handset at master. Hands free at sub station. Calling: Master to sub or other master: By voice (TALK) or tone (TALK & ALL CALL simult.) Sub to master: Call button on sub activates tone and LED at master, remaining lit for approximately 20 seconds. Wiring: 2 conductors homerun to sub station (1-Master system only), 3-conductor, or loop multi- conductor with 2 common + 1 individual wire per sub station on wire run. Shielded cable is recommended. Single Master Systems without BG-10C: Aiphone #822202, 2 cond. 22AWG; #821802, 2 cond. 18AWG Multi-Master System (Can also be used in a single master system or systems with BG-10C): #822203, 3 cond. 22AWG; #822206, 6 cond. 22AWG. LAF-C to ea. BG-10C: Aiphone #822220, 20 cond. 22AWG. Wiring Distance: 650' with 22AWG; 1,600' with 18AWG. Dimensions: LAF-20C: 10-1/4" x 13-1/2" x 5-1/2". LAF-20CA: 10-1/4" x 17-3/4" x 5-1/2" (H x W x D) LAF-40C: 10-1/4" x 19-1/2" x 5-1/2". LAF-40CA: 10-1/4" x 23-1/2" x 5-1/2" LA-20AS: 10-1/4" x 7" x 5-1/2". LA-40AS: 10-1/4" x 12-7/8" x 5-1/2". Pg. 6 TROUBLESHOOTING GUIDE PROBLEM SOLUTION 1. No call tone or LED when sub calls master. 2. Call tone works, but no communication, or communication works, but no call tone. 3. Call tone is too loud or too quiet. 4. Master stations cannot call each other. 5. LED lights don't light up when calling master-tomaster. 6. Occupied light is always on. 7. When subs call in, multiple LEDs light up. 8. All Call doesn't work. 9. All call doesn't work, but adaptors are included. 10. When All Call is made, all station LEDs light up. 11. Feedback is heard between intercom stations in adjacent rooms. 12. System has AC hum when listening to another station from a master station. 1. Make sure jumper is installed between E & terminals at the master and all sub stations (in 2-wire configuration). 2. Same as #1 in 2-wire system. In 3 wire system, 1 & E are for communication, and 1 & -are for call-in. Check continuity and connection of wires. 3. Call tone volume control is located on main PC board under select switch panel (white 3-pos. switch). Level is set to maximum. Move to mid or low position. 4. The "C" terminal on the master station means "CALL", and provides master-to-master communication. Make sure the "C" of one master is connected to a designated station # on another master. 5. Station LEDs only light when a sub station calls. Responding master answers hands free, therefore not having to select a station. 6. Make sure all black OFF buttons on master(s) are off (pressed down). Check "R" wire for short to ground. If occupied light remains lit with "R" wire disconnected from master, internal damage has occured, and the unit must be sent in for repair. 7. Make sure station number wires aren't shorted together. Remove all jumpers between E & -in multi- master or 3-wire system. Test master by taking wires off # terminals, then momentarily shorting # terminal to ( neg). If more than one light comes on, internal damage has occured, and the master must be repaired. 8. All Call is an optional feature requiring a BG-10C and PS-1225UL for every 10-11 stations in the system. Make sure adaptors are wired properly. See diagram #3e. 9. Check connection of P1, P2, P3 terminals between master and BG-10C's. P1 should read at least 10V DC when All Call button is pressed. Voice is carried on P2, P3 wires. 10. If single-call sub stations are used, NP-25V capacitors must be installed as shown on diagram #3e. 11. Intercom stations should not be mounted back-toback on a common wall. Separate them by at least two feet, or on separate walls if possible. Adjust voice volume control to eliminate feedback. 12. Intercom wiring must be at least 20" away from any AC wiring, fluorescent lights dimmer switches, or other AC devices. Cross at 90 degrees when necessary. If shielded wire was used, tie all shields together and ground at one end to an earth ground. If noise persists, isolate source of noise and separate the intercom station and wiring from the source. Pg. 7 PRECAUTIONS & WARRANTY CAUTION * Do not connect any AC wires to any terminal on any unit, as fire or unit damage may occur. Connect only specified power source on +, -terminals. * Do not install more or different power sources than specified for the system. * Do not attempt to install or connect wires on LAF-C system while the system's power supply is plugged in. * LAF-C masters and related equipment, unless specified as "weather resistant",...
