Frequently Asked Questions - CAS 88306 GEV

How do I pair the indoor unit with the outdoor unit?

The GEV CAS 88306 comes pre-paired with compatible outdoor stations. Simply connect the two wires according to the wiring diagram. If pairing is needed, refer to the manual for specific instructions.

What batteries does the intercom use?

It uses 2 x AA batteries (not included). For longer life, use alkaline or rechargeable NiMH batteries.

Can I use the intercom without batteries?

Yes, you can power it via a DC 9V adapter (not included). Ensure the adapter polarity is correct (center positive).

How do I adjust the volume?

The intercom has two volume controls: one for the ringtone and one for conversation. Use the small sliders or dials on the side or back of the unit.

What should I do if the intercom does not ring?

First, check batteries or power connection. Ensure the outdoor unit is connected properly. If the ringer is off, adjust the ringer volume switch. If still not working, test with known good batteries.

How far can the indoor and outdoor units be apart?

Maximum distance depends on wire gauge. For standard 2-wire cable (0.5mm²), up to 100 meters is typical.

Can I connect multiple indoor units?

This model is designed for single indoor unit operation. For multi-unit setups, you may need additional amplifiers or a different system.

How do I clean the intercom?

Use a soft, dry cloth. Do not use water, solvents, or abrasive cleaners. For stubborn dirt, slightly dampen the cloth with water.

What does the door release button do?

Press the door release button to activate an electric strike on the outdoor unit, allowing a visitor to open the door.

Is the intercom weatherproof?

The indoor unit is for indoor use only. The outdoor unit (sold separately) is weatherproof. Keep the indoor unit away from moisture.

Introduction

This audio door phone system consist of a handset and an outdoor unit. With these you can establish an audio connection between the caller and yourself. Furthermore you have the option to add a door/gate strike (not included) into the system.

This audio door phone set uses a BUS-type protocol; i. e. just two wires are needed for all functions (ringing, speaking, listening, controlling the door/ gate strike)

Safety instructions

All warranty claims will be null and void in the event of any damage or loss caused by failure to observe these operating instructions. We accept no liability for any consequential losses or damage. We accept no liability for any personal injury or material damage caused by improper use or by failure to observe the safety advice. In these cases the guarantee and warranty are invalidated. For safety and authorization purposes it is not permitted to carry out any adaptation or conversion of the device.

1. Do not disassemble the unit.
2. Do not spray water on the indoor unit. Do not keep the outdoor unit where it will be exposed to extreme moisture.
3. Do not drop or shock the unit.
4. Remove the power cord from the wall socket when unit is not used for long periods.
5. This apparatus is designed for moderate climates. Do not use in high humidity, dusty or dirty areas.

Installing

Attention: if you like to test the units before final installation then don't do this with both units inside The same room-this could lead to a Larsen-effect (an annoying acoustic feedback of the indoor panel).

Installation of the outdoor panel (Fig. 3)

The outdoor panel is determined for wall-mounting.

Remove the front panel of the outdoor unit by loosening the two screws on the bottom (Fig. 3/1). Run the cables coming from the indoor unit (handset) through the cable opening (Fig. 3/2). Likewise, if required, the cables coming from the electric door/gate opener, too. Screw the rain cover housing with two screws at the location you provided. (Fig. 3/3). Now you can connect the wires according to the wiring diagram (depending on the number of indoor units see Figure 5 or 6) to the appropriate terminals (Fig. 3/4).

Before closing the front plate again, you can do still volume settings on the fixed back plate (Fig. 2b/8 and 9). Use a small, suitable screwdriver and turn the screw without much force (Fig 2b/8 volume control of the outdoor unit. Fig 2b/9 volume control of the indoor unit).

Tip: Seal the joints between the outdoor unit and the wall from three sides with silicone. Let the joint on the bottom open to decrease the likelihood of condensation.

Mounting the indoor unit (Fig. 4a and 4b)

First, open the indoor unit for this purpose, go with a suitable screw driver on the right bottom in the recess and pry through slight leverage the top of the lower shell. Mount the lower shell with four screws at the designated place on the wall. Now connect the wires as shown in figure 5. or 6-depending on your desired level of expansion.

Installation of the handset/ installation of outdoor panel/ caption of the badge

Connecting the handset.

See figures 5 or 6-depending on your desired level of expansion. To avoid problems high- and low-voltage cables should never be in the same cable conduit. Connect the cables as shown in the figures described.

Connecting the handset to the outdoor panel: Connect the power supply with the inside socket. Connect "L+" and "L-" of the handset with the terminals "L+" and "L-" of the outdoor panel.

Connecting an electric door/or gate strike. You can optionally include an electric door and/or gate opener in this system. For the connection diagram see Figure 5 or 6.

Caption of the name plate: Remove the cover of the bell in which you lever it by using a thin tool and carefully push it inside the notches (Fig. 7/A).

Set Up/Operation

Pressing on the push button of the outdoor panel, raises a signal on the handset (max. 6 times within 30 sec.). You can now pick up the phone and speak with the guest for a maximum of approx. 90 sec. To operate the electric door opener, briefly press (1 sec.) the —O button on the indoor unit. Important: It is essential that you use a door opener which has a memory function. Regarding the connection instructions see connection diagram 5 or 6. As a suitable electric door opener, we recommend such as item no. 007680 (110mm) or 007697 (250mm) from our GEV product range.

For connecting an electric gate opener connect the terminals "GATE" "GATE" of the outdoor panel and the two corresponding terminals (varies- depending on the manufacturer. Consult the manual of your gate drive engine) to your gate engine (terminals "GATE" "GATE" are dry contacts).

In case you have connected an external gate drive, enable this by a three-second push on the —O button on the phone.

Important: The functions can be executed only at the active unit and after lifting the handset.

Additional information

You have the option to connect up to three additional interior handsets in parallel (fig. 6/ order no. 8830601). When connecting multiple handsets, it is sufficient if you are using a single power supply for all stations. However, this power supply has to be the one which is the closest to the outdoor panel. In order to

communicate internally, press the button. This will trigger a collective call and establish a connection to the remote handset which is being picked up first (for approx. 30 sec.). As long as there's an internal connection, the voice contact to the outdoor panel is locked. The intercom function is interrupted in case there is an external call coming in.
