LEF-3L

3-Call Master Station with Selective Control Capability (Door Release or Camera Call-up)

Used with LE-D, LE-DA, LE-DL, LS-NVP/C Door Stations

- SUPPLEMENT TO LEF INSTRUCTIONS -

The LEF-3L is a compact, wall or desk mount master station able to selectively release a door or call up a camera.

Used with any LE-(except LEF-3,5 and 10) or LS-series (North America only) remote station, communication can be

established with each station by selecting the channel on the master station. While the channel is selected, pressing

the door release button (left of TALK button) will release only the associated door. When used for camera call-up, a relay

closure will be maintained as long as a station is selected. The system can have up to four stations, in any combination of

masters or door stations (e.g. 2 masters and 2 doors). Master-to-master communication is also a standard feature.

(If communication between masters is not required, multiple LEF-3L's can be used to talk to 3 door stations.)

PRECAUTIONS

WARNING

1. Do not dismantle or alter the unit. Fire or electric shock could result.

2. Do not connect any non-speciﬁ ed power source to the +, - terminals, and do not install two power supplies in parallel to a single input. Fire, damage to the unit, or system malfunction could result.

3. Keep the unit away from water or any other liquid. Fire or electric shock could result.

4. When existing chime wires are used, it is possible that they contain AC voltage. Electric shock or unit damage could result. Ask a qualiﬁ ed technician.

5. Do not use DC power supply with a voltage other than speciﬁ ed. Fire or electric shock could result

CAUTION

1. Before turning on the power, make sure wires are not crossed or shorted. Fire or electric shock could result.

2. When mounting the unit on wall, install the unit in a convenient location, but not where it could be jarred or bumped. Injury could result.

3. For DC powered systems, use Aiphone power supply model speciﬁ ed with system. If non-speciﬁ ed product is used, ﬁ re or malfunction could result.

4. Do not install or make any wire terminations while power supply is plugged in. It can cause electrical shock or damage to the unit.

5. In case of electrical storms, unplug the unit from AC outlet. If not, ﬁ re or electric shock could result.

6. Do not install the unit in any of the following locations. Fire, electric shock, or unit trouble could result.

* Places under direct sunlight, or near heating equipment that varies in temperature.

* Places subject to dust, oil, chemicals, hydrogen sulﬁ de (hot spring).

* Places subject to moisture and humidity extremes, such as bathroom, cellar, greenhouse, etc.

* Places where the temperature is quite low, such as inside a refrigerated area or in front of air-conditioner.

* Places subject to steam or smoke (near heating or cooking surfaces).

* Where noise generating devices such as dimmer switches, invertor electrical appliances, are closeby.

7. Do not install the unit in a location subject to constant vibration or impact. If dropped, injury or unit damage could result.

(Negligence could result in death or serious injury.)

(Negligence could result in injury or dam age to property.)

GENERAL PRECAUTIONS

1. Keep the unit more than 1 m (3.3') away from Radio or TV set.

2. In areas where broadcasting station antennas are close by, the intercom system may be affected by radio frequency interference.

3. The unit will be inoperative during a power outage.

4. This unit is for indoor use only. Do not use outdoors.

Before Installation:

· Make sure you have the proper power supply(ies) and all necessary and compatible equipment for the system.

· Lay out your system in advance, assigning station numbers for all sub station locations.

· Surge protection for the intercom equipment is recommended. Add SA-1 surge arrestors for the power supply, plus one

Wire:

Operation plate

PUSH

Directory card

To remove the operation plate, push either left or right side of the plate.

· Shielded wire is strongly recommended. Use the proper gauge for the distance being run.

· Wiring between masters must be a multi-conductor cable. If more than one cable is used to connect masters, the "E",

"C", and number terminal wires must be in the same jacketed cable. If necessary, run multiple "E" wires, one in each cable.

Wiring Method:

· Run intercom cables at least 50cm (20") away from all AC wiring, ﬂ uorescent lights, dimmer switches, and other

electrical or electronic devices. Intercom wiring can cross AC wires at 90 degrees.

· Sub stations can be homerun to the nearest master station, or daisy-chained. If daisy-chained, include 2 common wires

plus 1 individual wire per station on the run.

· In a SINGLE MASTER SYSTEM ONLY: Subs can be wired with 2 conductors homerun. Jumpers between "E" and "-"

must be attached on all subs and at the master station.

Intercom Locations:

· Do not install intercoms near dimmer or light switches, or other electrical wall devices.

· To prevent feedback, do not place sub stations back-to-back on a common wall.

· Near alarm panels or other electronic equipment that may emit data noise.

· Behind a doorway or any other area that may block access to the unit.

Before actually installing the LEF system, Precautions on Installation & Wiring must be

■

thoroughly read and understood.

To access the inside of the unit for making wire connections:

1. Remove Operation plate & Directory card and loosen the screw on the front of the unit. (Do not remove screw)

2. Carefully lift front of intercom up and off the back chassis.

3. If desired, unplug connectors and set unit aside during mounting and wiring of the back chassis.

4. When wiring is completed, plug in connectors and put unit back together. Peel protective covering off of Operation plate.

LEF surface mount master stations are set in the "B" position from

“A” position: Mutes call tone at master while system is in

occupied mode.

“B” position: Call tone is heard when master is in occupied



mode.

*No call tone between masters.

Cable requirements

■

Use multi-conductor cable with an overall shield, non-twisted, 22AWG to 18AWG (0.65mm to 1.0mm), to accommodate

the maximum number stations in the system.

Use the gauge speciﬁ ed for the maximum distance between the two farthest stations.

Power supply

■

The entire LEF system can be powered by one power supply (PS-1225UL/PS-1225S 12VDC 2.5A or PS-1215DIN

12VDC 1.5A), located near the center of the wire run.

For a system including the All Call and Chime with the BG-10C, one PS-1225UL(S) or PS-1215DIN will power the BG-

10C and the LEF system.

The LED lights will operate with a power source from 6VDC - 24VDC. The

Proper power supply is the PS-1225/UL/S, or PS-1215 DIN.

door station(s) and remove all of the jumpers.

If the units are too close to an AC source such as AC wiring or dimmer

switches, move the intercom at least one stud space away from the AC

source. Other precautions include using shielded cable. If shielded wire was
