Intercom and Mamad: Checking Functionality and Connectivity

To validate the operation of the intercom connected to the mamad, you must test the two-way audio communication between the street unit and the handset in the secure room, verify the electric opening of the building’s main door, and confirm that the alert signal is transmitted without interruption to the internal control panel. An electrical continuity test is necessary to ensure that a power outage does not isolate the secure room from the rest of the building. We systematically perform these checks when preparing a property for a new tenant to guarantee occupant safety.

Verifying the intercom and the connection to the mamad

The intercom system in Israel is not limited to simple communication between the living room and the entrance. In recent buildings or those renovated according to security standards, the system must imperatively allow a direct connection with the mamad. During an inspection, we follow a precise testing protocol to isolate defective components.

• Audio communication test between the street unit and the interior handset: we ask a third party to call from the street to check for static or sound dropouts.
• Building door opening control via the command button: we test the door’s electric actuator to confirm that the command signal is transmitted and executed.
• Verification of signal transmission to the secure room for security alerts: we verify that the handset located in the mamad receives the call as a priority, without interference with other units in the apartment.

If the sound is inaudible in the secure room but clear in the living room, the problem generally stems from the specific wiring serving the mamad. This distinction is crucial to determine if the repair falls under apartment maintenance or the building’s main riser. A poor connection can prevent an occupant from receiving crucial security instructions during an alert.

Distinction between the building intercom and the mamad alarm

The building’s communication system and the internal security device of the secure room should not be confused. The former is a convenience feature, while the latter is a civil defense element. The intercom system is managed by the vaad bayit, whereas security devices specific to the mamad are the direct responsibility of the owner.

We distinguish these two systems by their power supply and wiring. The standard intercom uses the building’s electrical network, while the mamad communication system must have its own independent power source. To validate this, we perform the following tests:

1. Electrical continuity test between the standard intercom and the secure room control panel to ensure no short circuit blocks the signal.
2. Backup battery autonomy verification: we cut the main power supply to confirm that the mamad handset remains operational.

This distinction is fundamental for Mamad door verification in Israel. An intercom that works in the living room but shuts down during a power outage leaves the secure room vulnerable. The owner must ensure that the backup system is functional before any rental.

Role of the vaad bayit in common system maintenance

The management of intercom failures depends on the origin of the defect. The vaad bayit is responsible for the maintenance of collective equipment. If the street unit is damaged by vandalism or if the building’s main riser has a signal defect, the repair costs are the responsibility of the homeowners’ association. On the other hand, if the defect is located on the handset inside the apartment or on private wiring, the owner must intervene.

To identify responsibility, we follow this control method:

We advise always requesting written confirmation from the vaad bayit manager before incurring repair costs. If the problem is collective, the building must cover the intervention. If you wish to rent from abroad, fluid communication with the building manager is essential to manage these unforeseen events without traveling.

Technical inspection of wiring and communication equipment

When a malfunction is detected, we recommend bringing in a professional to test the integrity of the lines. In Israel, systems can be analog or digital, and wiring complexity increases with the addition of security equipment in the mamad. A technician must verify that electromagnetic interference does not disrupt communication.

The technical inspection must cover the following points:

• Condition check of speakers and microphones: we verify the absence of sound distortion that could prevent understanding emergency messages.
• Verification of exterior box sealing: the street unit is exposed to the elements. A poorly sealed box can cause oxidation and intermittent failures.
• Electrical voltage test on mamad connection points to ensure the door opening command signal is sufficient.

If renovation work is underway, such as Renovating a mamad floor in Israel, it is imperative to protect the intercom cables. Mortar or tile installation can crush communication lines and permanently isolate the secure room.

Failure management and responsibilities of the owner and tenant

The allocation of costs in the event of an intercom failure follows specific usage rules. The tenant is responsible for routine maintenance and normal use of the equipment. If the handset is broken due to impact or misuse, the replacement costs are their responsibility. The owner, however, must ensure the structural functionality of the system.

We apply the following distinction to avoid disputes during the property handover:

• Routine maintenance: replacing handset batteries, cleaning speakers, protection against impacts. These items are the responsibility of the tenant.
• Major repair: replacing the main riser, repairing the street unit, restoring embedded wiring. These items are the responsibility of the owner.

In the event of a failure in the secure communication system, the tenant is obligated to report the anomaly immediately to the owner or manager. A defective intercom in an apartment equipped with a mamad constitutes a security defect that can engage the landlord’s liability in the event of an incident.

Drafting maintenance clauses in the lease agreement

To protect your investment, the lease agreement must be explicit regarding the state of the communication system. We perform a thorough verification during the move-in inspection to note the exact operation of each component. It is not enough to simply state « intercom functional »; you must specify that the connection to the mamad has been tested and validated.

Clauses should include:

1. Details on the operational status of the intercom system and the secure connection at the time of move-in.
2. Procedures for equipment replacement in case of wear and tear (natural aging) or damage (tenant fault).
3. The link to the shtar ’hov signature: although the shtar ’hov is a promissory note and not insurance, it helps guarantee the reimbursement of repairs related to material damage caused by the tenant.

A well-drafted clause avoids endless debates regarding the distinction between a technical failure and damage. In the event of a dispute, the owner can rely on the initial inspection report to justify a request for reimbursement of repair costs.

Verification checklist before a new tenant moves in

Before handing over the keys, we perform a final series of tests to ensure the apartment is ready to be lived in safely. This step is crucial to prevent the new tenant from contacting you in their first week regarding a communication problem.

Here is the list of control points we follow:

• Incoming call test from the street to the living room and to the mamad: we verify that the call reaches both units without excessive delay.
• Sound clarity verification: we ensure the sound is loud enough to be heard in the mamad, even if it is closed.
• Visual check of the condition of control buttons and the handset: we check for signs of excessive handling or loose components.
• Door opening test: we confirm that the tenant can open the building door from any unit in the apartment.
