⚠️ IMPORTANT: How to Choose the Correct Frequency for Your System
​Before purchasing, you must ensure that the frequency of this device matches your existing Visonic control panel. Wireless components of different frequencies will not communicate with each other.
​Method 1: Check the Label on Your Current Equipment
​The easiest way to find your frequency is to look at your existing control panel or one of your current motion sensors/remotes:
​Open the battery compartment or look at the back of the device.
​Look for a small white sticker indicating the frequency.
​It will typically say: 433.92 MHz, 868.95 MHz, or 915 MHz.
​Method 2: Identify by Geographic Region
​Visonic systems are factory-preset to comply with local radio regulations:
​Europe / UK / Middle East: Typically uses 868 MHz (Note: Israel uses 433 MHz).
​USA / Canada / Australia: Typically uses 915 MHz (PowerG) or 315 MHz (Legacy).
​Latin America / Parts of Asia: Often uses 433 MHz.
​Method 3: Check Your Panel's Model Name
​PowerMax / PowerMaster: These series exist in all frequencies. You must verify the specific version.
​Model Suffix: Check if your model number ends with a specific frequency code (e.g., PM-30-868 means 868 MHz).

Critical Information for Buyers: Please note that your system supports frequency 868 MHz, version 1 (868-1 only , not work with 868 -0,2,3)

and that your system:  PowerG Visonic PowerMaster ,

the detector will not work in another system (The information in your back panel shows which frequency your system supports) You are not sure not to buy send me a picture of your keyboard sticker like in the picture



Visonic PowerMaster Wireless Smoke Detector SMD-426 PG2 868-1 mhz

Product Description

SMD-426 PG2 is a fully supervised wireless photoelectric smoke detector that is compatible with PowerMaster® wireless alarm systems. Designed for a wide range of residential and commercial applications, the easily installed smoke detector has a streamlined design and an extended battery life for easy and low-cost maintenance.

With superior smoke detection sensitivity levels, SMD-426 PG2 provides an early warning of developing fires. When smoke is detected, the detector issues both sound and transmitted alarms. To ensure highly reliable communication, SMD-426 PG2 uses Visonic's ground-breaking PowerG technology which combines several field-proven advanced technologies and the highly reliable AES encryption method. This combination of technologies delivers unmatched advantages for professional installers, central monitoring stations and end-users alike.

SMD-426 PG2 complies with the strictest international certifications for safety products in Europe, and is designed to comply also with UL 268.
 
Features:
Longer battery life for 5-8 years (in typical use, according to battery type)
Provides sound and transmitted alerts (for smoke, tamper, low battery)
Loud (85db) alarm sound at 3m (10ft)
Transmission range is far greater than the industry standard - enabling repeater-free installations even in large premises
Visible signal quality indication shown on the device
PowerG two-way Frequency Hopping Spread Spectrum FHSS-TDMA technology - provides robustness and reliability closer than ever to wired intrusion alarm systems
Employs the proven AES-128 (128 bit key) advanced encryption algorithm for correct message identification and protects the alarm system from code grabbing and other attacks
Continuously measures communication quality and automatically sets transmission power to the minimum required for reliable communication
Configured from the panel – no hardware switches and no need to re-open the detector once closed
Audio and visual sensitivity degradation indicators notify when the sensor needs to be cleaned
Simple wall or ceiling installation, with bracket
Back tamper
Fully certified by the most strict and demanding international standards for safety products in Europe (EN 14604 and EN 54-7 for smoke detectors) and is designed to comply also with UL 268

Please note:
PowerMaster and PowerG panels and accessories are NOT compatible with PowerMax panels and accessories
