An accessible toilet and six service desks in one system
One 433.92 MHz receiver at the porter’s lodge for the customer service office and the accessible toilet: a toilet kit, under-counter buttons at six desks and a signal unit for the porter.
- 6service desks
- 1accessible toilet
- 8transmitters in one receiver
01 / Investment context
What problem does this configuration solve?
In the municipal office, the customer service office has six desks, with a toilet for people with disabilities next to it. An accessible toilet needs a way to call for help: a visitor who feels faint or falls behind a closed door must be able to signal with one movement, and someone must come to them.
At the desks the problem is different. A conversation with a visitor sometimes gets out of hand, and the clerk wants to call the manager or the municipal police — but without the visitor noticing, because a raised voice or reaching for the phone can make things worse. The office does not want to run two separate systems for these two needs.
The investor’s goal: One receiver at the porter’s lodge for the toilet and the desks: the porter sees the number of the spot and acts according to procedure, while the visitor at the desk does not see the call.
How does this configuration work?
The toilet is covered by a toilet kit (TdN-01): a button with cancel key (PNH-201C) and a pull-cord transmitter with cancel key (PNH-201SC) in the toilet, a signal unit above the door on the corridor side and an identification receiver (IDO-04/99) at the porter’s lodge. The toilet transmitters repeat the call every 30 seconds until someone cancels it with the button on the spot — so a call from the toilet ends at the visitor’s side.
Each of the six desks has a call button under the counter (PNP-202), programmed into the same receiver but not into the signal unit by the toilet — nothing lights up and nothing sounds in the service hall. The receiver shows the transmitter’s number, and a list next to it gives the place: “1–6 — desks, 7 and 8 — toilet”. The receiver’s relay switches on a signal unit with adjustable volume at the porter’s lodge (SWR-108).
The receiver, the signal unit at the porter’s lodge and the signal unit above the toilet door run on 12 V DC from the system’s power supplies (SPR-ZS1). If the manager of the service hall is to receive calls from the desks directly, they can carry a pager (OBI-4SH) programmed only for the under-counter buttons, in which each desk is a separate zone.
02 / Operating principle
From signal to action.
Calls from the accessible toilet and six desks reach one receiver at the porter’s lodge, with the number of the spot.
Accessible toilet

Porter Calls the manager or the municipal policeHears the call from the signal unit at the lodge and responds according to procedure.
The visitor at the desk does not see the call. The under-counter buttons do not trigger the signal unit by the toilet; the hall manager can carry a pager set to them alone.

Devices in this configuration
An example selection — the number of devices depends on the site.
IDO-04/99
The kit’s identification receiver, at the porter’s lodge: stores the eight transmitters of the toilet and the desks, shows the number of the one calling and switches on the signal unit through its relay.
Quantity: included in TdN-01
PNH-201C
Button in the toilet: the call repeats every 30 seconds until someone cancels it on the spot with the cancel key.
Quantity: included in TdN-01
PNH-201SC
Pull-cord transmitter in the toilet with a 2 m chain: the call repeats every 30 seconds until it is cancelled on the spot.
Quantity: included in TdN-01
PNP-202
Button under the service desk counter: the clerk calls for support with a hand movement the visitor cannot see. Battery-powered.
Quantity: 6
SWR-108
Light-and-sound signal unit at the porter’s lodge, switched by the receiver’s relay; the volume is set with a knob on the front panel.
Quantity: 1
SPR-ZS1
Mains power supply, 230 V AC: one at the porter’s lodge for the receiver and signal unit, the other by the toilet door for the signal unit above the entrance.
Quantity: 2
OBI-4SH
Pager for the manager of the service hall, programmed only for the under-counter buttons: a call from a desk reaches them directly, with the desk’s zone number.
Quantity: optional

04 / Value for the investor
What does this solution give you?
One system, one place
Calls from the toilet and the six desks go to one receiver at the porter’s lodge — one point of response, one maintenance check, one procedure.
The visitor does not see the call
The button is under the counter and nothing lights up in the service hall — the clerk asks for support without raising their voice or escalating the conversation.
The porter knows where to go
The number on the display points to the toilet or a specific desk, so support goes straight to the right place.
05 / Before installation
What needs to be settled for a similar investment?
Before devices are chosen, what matters is the site’s conditions and how the system ties into the final installation.
Requirements to verify
- This is a channel for calling staff support, not a certified hold-up alarm system — it is not connected to the police or a security company.
- The porter’s procedure for each type of call: toilet — go there; desk — call the manager or the municipal police.
- The design requirements for the accessible toilet — button height, pull-chain length, signalling and cancelling — are set by the building’s designer.
- 230 V power at the porter’s lodge and by the toilet door for the power supplies of the receiver and signal units.
- The list of numbers next to the receiver — and keeping it up to date when the desk layout changes.
