Dealer for System Sensor
System Sensor Detector Bases in Bhopal
Fire Protection System (FPS), a System Sensor dealer in Bhopal, supplies System Sensor detector bases: the B501AP standard addressable base, the B524HTR heater base and the B524IEFT-1 isolator base for Series 200 detectors, and the B401 plug-in base for 2-wire systems. FPS installs, tests and maintains them across Madhya Pradesh.
Where to use Detector Bases
- Offices and commercial buildings
- Malls and retail spaces
- Residential complexes
- Banks
- Schools, colleges and other educational institutions
- Addressable loops with Series 200 detectors
- Areas where frost or condensation can form in the detector (heater base)
- Long addressable loops that need short circuit isolation (isolator base)
System Sensor Detector Bases models
System Sensor B524HTR Analogue Heater Base
A two-wire heated base for System Sensor 200 analogue addressable detectors, used where frost or condensation could otherwise cause false alarms.
System Sensor B524IEFT-1 Analogue Isolator Base
An isolator base for System Sensor 200 analogue addressable detectors that stops a short circuit from disabling the whole loop and restores the loop automatically once the fault is fixed.
System Sensor B401 Plug-in Detector Base
A plug-in base for System Sensor smoke and heat detector heads in 2-wire systems, with screw terminals for power and remote annunciator connections.
How to choose
A detector base is the part fixed to the ceiling and wired to the system; the detector head plugs into it. First match the base to the detector. The B501AP, B524HTR and B524IEFT-1 are for System Sensor Series 200 addressable detectors, and the B401 is a plug-in base for System Sensor smoke and heat detector heads in 2-wire systems, with screw terminals for power and a remote annunciator.
For most addressable points the B501AP is the standard choice. It works with the 500, 200, 200+ and 200 Advanced sensor ranges, comes in white, ivory (IV suffix) or black (BK suffix), and has a tamper-resistant feature enabled by breaking off a plastic tab, after which the detector cannot be removed without a tool.
Choose a specialist base where the site needs it. The B524HTR heater base warms the sensor by a few degrees to stop condensation or frost building in the chamber and causing false alarms; it gives 2.6 watts of heating at 28VDC. The B524IEFT-1 isolator base cuts off the part of the loop with a short circuit so the rest of the loop keeps working, and restores the loop automatically once the fault is cleared.

Frequently asked questions
What is a detector base?
It is the mounting part that is fixed and wired in place; the detector head plugs into it. This makes it easy to remove the head for testing, cleaning or replacement without disturbing the wiring.
What does an isolator base do?
It separates the section of the loop that has a short circuit from the rest of the circuit, so the whole loop is not disabled. On the B524IEFT-1 the loop is restored automatically when the short is corrected, and up to 99 isolators can be used per loop.
When do I need a heater base?
Use the B524HTR where frost or condensation may build up in the detector chamber and cause false alarms. It raises the sensor temperature by a few degrees to prevent this.
Which base suits Series 200 addressable detectors?
The B501AP standard base, the B524HTR heater base and the B524IEFT-1 isolator base are all made for System Sensor Series 200 analogue addressable detectors.
Does FPS supply System Sensor bases in Bhopal?
