BLITZ Conventional Multi Sensor Detector - Combines Smoke and Heat (Fixed + Rate-of-Rise) Detection in One Unit, CE & ISO 9001 Certified
46ر.س
Product description
Overview
- The BLITZ Conventional Multi Sensor Detector is a conventional fire detection device designed to work with all conventional control panels, combining both smoke and heat detection functions in a single low-profile unit with polarity-free wiring, simplifying installation and reducing the risk of connection errors. The device provides visual indication via an LED that blinks during normal operation and stays lit when an actual fire condition is detected. On the heat detection side, the device functions as a combined fixed-cum-rate-of-rise heat sensor based on a thermistor, triggering an alarm when the temperature reaches 59°C (fixed detection) or when the rate of temperature rise exceeds 11°C per minute (rate-of-rise detection). On the smoke detection side, it features a unique sensing chamber designed to detect smoke produced by a wide range of combustion sources, with an insect-resistant design to reduce false alarms. It features a standard 100mm base and a sleek, low-profile housing. CE and ISO 9001 certified. Available through Al-Najma Al-Wataniyah with guaranteed quality and fast delivery across Riyadh, Dammam, and all KSA regions.

Industrial Applications
- B2B Sectors — Detailed Engineering Use Case:
| Sector / Application | Engineering Use Case Details |
| Warehouses and storage centers | Installation in large spaces exposed to both electrical (heat) hazards and slow-burning (smoke) fires, benefiting from dual detection in one device to cover both hazard types without doubling installation points |
| Factories and production workshops | Installation in manufacturing areas where elevated heat risks (equipment, motors) coincide with smoke risks (flammable materials), benefiting from fixed and rate-of-rise heat detection (59°C or 11°C/min) to catch electromechanical faults early |
| Hotels and hospitality facilities | Installation in rooms and corridors for comprehensive (smoke + heat) coverage in one low-profile device suited to interior design, benefiting from polarity-free wiring to speed up installation on large projects |
| Offices and administrative buildings | Installation in server rooms and electrical equipment rooms where heat detection provides added protection for sensitive equipment, alongside conventional smoke detection for general office spaces |
| Kitchens and laundries of large commercial facilities | Installation near moderate heat sources where combining both detection modes provides more accurate coverage than relying on a single smoke detector, which may be prone to false triggering from steam |
| Renovation and safety system upgrade projects | Replacing old single-function smoke or heat detectors with one device covering both types, reducing the total device count in the project without sacrificing coverage level |

Frequently Asked Questions
Q1: Does this detector actually combine smoke and heat detection?
- Yes, the device is designed as a multi-sensor combining an optical smoke sensing chamber and a heat sensor (thermistor) operating in fixed mode (59°C) and rate-of-rise mode (11°C/min) within a single unit.
Q2: What does "polarity free" wiring mean?
- It means the device can be connected to either wire terminal without needing to observe positive/negative polarity, speeding up installation and reducing the risk of wiring errors compared to devices requiring specific polarity.
Q3: How can normal operation be distinguished from a fire condition via the LED indicator?
- Per the data sheet, the LED blinks intermittently to indicate normal operating conditions, and stays lit continuously when an actual fire condition is detected.
Q4: What operating voltage does this detector require?
- The detector operates within a 9V to 33V DC range with voltage ripple less than 1V, making it compatible with a wide range of conventional control panels.
Q5: Is delivery available to Riyadh, Dammam, and all KSA regions?
- Yes, supply is available across all KSA regions with bulk quantities available for B2B projects.
