NRP-102K
Transmitter with link supervision in the boiler house, 12 V DC, IP66: input 1 — boiler fault, input 2 — flooding. It also sends link and power supervision signals.

Boiler house faults and a broken link both visible in the estate management office
Radio alarm transmission with link supervision between the boiler house and the estate management office: two alarm states, link and power supervision, plus a text message to the maintenance technician after hours.

01 / Investment context
What problem does this configuration solve?
The estate has its own gas boiler house that heats its buildings. It stands 600 m from the management office and runs unattended — the maintenance technician looks in during rounds.
The boiler controller provides a “fault” contact, and a flood sensor sits on the floor. Today both signals end in the boiler house: the office only learns of a fault from residents whose radiators are going cold, and of flooding on the next round.
The office wants to see both states at its desk and — just as important — to know when the link itself stops working. No alarm should mean “all is well”, not “we don’t know”.
The investor’s goal: Boiler faults and flooding are visible in the management office, go by text to the technician after hours, and a lost link is reported like an alarm.
How does this configuration work?
A transmitter with link supervision (NRP-102K) works in the boiler house, powered at 12 V DC with battery backup. Input 1 is the boiler controller’s “fault” contact, input 2 the flood sensor’s contact. The transmitter also sends link and power supervision signals.
In the management office a receiver with link supervision (RP10-2K) reports boiler fault, flooding, lost link and lost transmitter power separately. Its output switches on a signal unit with volume control (SWR-108) in the office, so that the alarm can be heard throughout the room without being needlessly loud.
The receiver’s outputs are also wired to a GSM transmitter in a housing with a power supply (ATG-SG4set), which sends a text message to the technician — after office hours the alarm does not go unanswered. If the estate’s buildings block the radio path, a repeater with link supervision (RTS-1000K) carries the signal.
02 / Operating principle
From signal to action.
Boiler faults and flooding reach the management office 600 m away by radio, and the technician by text after hours.

Devices in this configuration
An example selection — the number of devices depends on the site.
RP10-2K
Receiver with link supervision in the management office: it reports both states as well as a broken link and lost transmitter power. The second site in the basic version stays in reserve.
Quantity: 1
SWR-108
Light-and-sound signal unit in the management office, switched by the receiver’s output. The volume is set with a knob on the housing.
Quantity: 1
ATG-SG4set
GSM transmitter in a housing with a power supply, next to the receiver: it turns the states on the receiver’s outputs into a text message to the technician.
Quantity: 1
Installation component
Buffered 12 V DC power supply with battery
Powers the transmitter in the boiler house and the receiver in the office, also during a mains failure, and the receiver monitors the transmitter’s power and reports its loss.
Quantity: 2
RTS-1000K
Repeater with link supervision — if the radio test shows that the estate’s buildings block the path; it extends the range by about a kilometre. Powered at 12 V DC.
Quantity: optional
Catalogue figures describe a device under stated conditions, usually in open terrain, and are not a guaranteed range in every installation. Device quantities in the examples are indicative.
04 / Value for the investor
What does this solution give you?
No alarm means something
A lost link and lost transmitter power are reported like alarms, so no alarm means the link is working and the boiler house reports no fault.
Sooner than residents’ calls
The office knows about a boiler fault before residents start calling about cold radiators — and can send the technician sooner.
The technician after hours
The text message reaches the technician’s phone at night and at weekends too, when the management office is closed.
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
- The system does not replace the boiler house’s safety automation or its gas detection — it only passes on the states they provide.
- Volt-free “fault” contacts from the boiler controller and the flood sensor, wired to the transmitter.
- 12 V DC with battery backup in the boiler house and the office, a backup battery for the GSM transmitter, and a radio test along the 600 m route between buildings; the repeater depends on it.
- The technician’s phone number, the message text and how the alarm is to be cleared in the office — the receiver’s operating mode (stand-alone or with a control panel) depends on it.
