Sivas Fire Systems Maintenance and Periodic Inspection

Welding sparks go upward: It starts from the ceiling of the maintenance hangar in Sivas

When the body seam of a freight car is being pulled, the spark does not fall downward but is thrown upward. This is the frame that tells the story of Sivas industry: heavy steel construction at the bottom, hangar space exceeding ten meters at the top, suspended welding smoke in between. Both detection and suppression are designed according to that space; by the time the smoke reaches the detector, it has cooled and stratified. The identity of the city has been shaped since 1939 by TÜRASAŞ Sivas Regional Directorate (formerly known as TÜDEMSAŞ), which manufactures and repairs freight cars: a site exceeding four hundred thousand square meters, enclosed area exceeding one hundred thousand square meters.

One province, five dissimilar fire scenarios

• Rail systems and metal works: freight car manufacturing, casting, machining. Hot work permits and high ceiling detection are on this group's agenda.
• Cement, brick-tile, iron-steel: Cement plant in the Danişmentgazi direction, brick-tile kilns, rolling mill; dense dust and continuously hot surfaces together.
• Agriculture-based industry: Around Şarkışla, Gemerek and Şarkışla Agriculture-Based Specialty Organized Industrial Zone: flour, feed, milk and meat processing; dust explosion is a separate heading on the flour-feed side.
• Mining and energy: Divriği iron ore operations, Kangal lignite basin; conveyor belt and coal stockpile are a separate fire class.
• Thermal accommodation: Hotels on the line of Hot Çermik, Cold Çermik and Kangal Fish Spa: facilities where maintenance is performed while guests are sleeping.

As ceiling height increases, detector wakes up late

The height at which the point detector stops working

In the freight car hangar, standard optical point detector in the cement packaging hall loses its reliability after eight-nine meters: the smoke cools before reaching the ceiling and remains suspended a few meters below the detector. For this reason, the maintenance visit does not only ask "is the detector working," but also "is this the right device for this ceiling." Beam detector and aspirated sampling (ASD) are evaluated together; the criterion is CEN/TS 54-14.

The silent cost of hot work: permanent isolation

The most common scenario we see in welding and grinding halls is this: the operator tired of false alarms isolates the detector, isolation drops from the agenda, the hall operates unprotected for months. During the round, panel event logs are scanned, permanently isolated addresses are listed; heat detector or dual verification is recommended around the welding station. For dust collection lines, spark detection-suppression equipment is discussed separately (factory solutions).

At 1,280 meters elevation in winter: a frozen line does not extinguish a fire

Sivas is located at approximately 1,280 meters elevation, a plateau city known for its harsh winters. The consequence is clear: the wet-pipe sprinkler riser in the unheated hangar, the external hydrant line without drainage, and the cold pump room silently disable the system at the first hard freeze. The facility appears "installed"; the day the deficiency is discovered is the day of the fire.

• Transition to dry-pipe or pre-action system in unheated space is necessary; if available, compressor cycle and air leak measurement.
• Antifreeze riser mixture density measurement; external hydrant, test line and drain valve drainage control.
• Pump room temperature, diesel block heater, battery and fuel condition; level switch and freeze prevention device in the fire tank.

These items are carried with a separate list during the pre-winter round; the criterion is TS EN 12845 for wet systems, NFPA 25 for pump and valve testing. For unheated high-bay spaces warehouse and storage solutionsA zone monitoring module connects an entire conventional detector line to the addressable loop. Critical areas are renewed with addressable devices while secondary zones continue to operate with their existing wiring. This provides significant cost advantage in capacity upgrade and renovation projects.

Which system, which criterion is being checked

The regulation does not set the period; frequency is delegated to these standards and the manufacturer's manual. Scope periodic inspection forms, pricing structure maintenance prices page.

At the thermal hotel, maintenance is completed before guests wake up

Accommodation facilities on the Çermik and Kangal line differ from industry in two respects: occupancy is seasonal, but the facility is full at night. Siren testing, announcement testing and fire door control are planned for low occupancy windows; progression is made floor by floor, and the completed floor immediately returns to service. Humidity alarm buttons in pool and steam areas, siren body and cable passages accelerate corrosion (hotel solutions).

From Ankara to Sivas: how the work actually proceeds

We have no signage in Sivas; neither branch nor dealership. The team departs from Ankara Yenimahalle, with over four hundred kilometers of road in between. The honest equivalent of this distance is this: we do not promise same-day inspection for Sivas, we cannot. We structure planned maintenance with regional round logic — in the same window, central organized industrial zones, the Şarkışla-Gemerek axis and facilities group in the Kangal-Divriği direction are grouped, the route is divided not to one job but to a route. In emergency breakdown, the process begins without waiting but with a phone call: remote preliminary diagnosis is made with panel error code and photo, where unresolved, the dispatched vehicle is loaded with spare parts suited to the panel type. Operations nationwide service and emergency repair service are on the pages; the situation is different within Ankara, inspection is free of charge (Ankara maintenance page). In the contract, we reduce a scattered facility to a single point of contact: all systems from detection to gas suppression are combined in one contract, those who wish also add camera maintenance.

Share hangar dimensions for the first conversation

Which approach will be discussed becomes clear in a few measurements. Before requesting a tour plan, the following:

• The hangar's width, length and ridge/ceiling height; is the roof flat or pitched.
• Whether the volume is heated, whether doors remain open throughout winter.
• If hot work is present, the number and location of welding-grinding stations.
• Panel brand and model, ongoing fault record.
• Condition of sprinkler, hydrant and pump group, last test record.

To Set Up Your Maintenance Program

One contract, a solution for everything: we provide end-to-end maintenance to fire detection, gas suppression, sprinkler, hydrant, and pump units in their entirety; if you wish, camera (CCTV) system maintenance can also be added to the same contract.

If you do not have the brand, age, and last maintenance record of the existing system on hand, that is not a problem; the first step is anyway inventory and current condition assessment. Setting up an annual program without seeing what is there in the field means selling maintenance for a system that does not exist.

You can examine your system brand's product equivalents in our product catalog ; for requirements specific to your facility's use class, you can visit our sectoral solutions pages.
