  • LDF SUPPLEMENT TO LAF-C/CA INSTRUCTIONS - The LDF Loudspeaker Intercom and External Control System is designed for communication between a central master station and remote intercom stations. The LDF is an expanded feature version of the LAF-C/CA system. All information regarding installation other than the external control functions is included in the LAF-C/CA instructions. In addition to communication to remote locations, external devices can be activated, such as activating a CCTV camera when the associated sub station is selected, selectively controlling the corresponding door strike or maglock, or both.

(Internal modification, soldering required.) OPERATION:
  • POWER SWITCH MUST BE ON FOR SYSTEM TO BE OPERABLE. 1. When a station calls in, press the selector button corresponding to the lit LED. 2. To speak to the person at the remote station, press the TALK button (or pick up the handset). Release TALK button to hear reply. Communication via the handset is VOX (voice actuated). 3. If the extra contacts are used as shown in the "camera call-up" diagram, activating a device that is to remain on for the duration of the call, the station's relay will stay activated as long as the selector button is depressed. 4. If the extra contacts are used as shown in the "selective door release" diagram, press the "door release" button while the selector button is depressed. This will activate the corresponding relay as long as the button is being held, which will activate the door release mechanism. 5. If both functions are used on a channel, the device connected to the "constant closure" relay will be on for the duration of the call. The "momentary closure" will only be active when the door release button is pressed. 6. When the conversation is completed, press the OFF button to the left of the station selector button. Hang up handset. SPECIFICATIONS Power Source: 12V DC at master. Use PS-1225UL. For additional information about this system, please refer to the LAF-C/CA instructions. Commun. Output: 800mW at 20 ohms Communication: Push-to-talk, release-to-listen (TALK button) or VOX handset at master. Hands free at sub station. Calling: Master to sub: By voice only Sub to master: Call button on sub activates tone and LED at master. LED remains lit for 20 seconds, and tone is momentary. Wiring: 2 conductors homerun to sub station (single-master system only), or loop multi-conductor with 2 common + 1 individual wire per sub station on wire run. Separate 2 conductor from RY-PA to external device. Shielded cable is recommended. Use Aiphone #822202 (2 cond., 22AWG) or #822203 (3 cond., 22AWG) wire. Wiring Distance: 650' with 22AWG; 1,600' with 18AWG. Pg. 2 LDF Instr. 1103BKJS
