HiLo Handy Little Relay 24VDC, Polarised
Compact HiLo 24V polarised relay for fire alarms & safety systems. 5A switching, 50×30×70mm. Voltage-free contacts.
The HiLo Handy Little Relay 24VDC is a compact, polarised relay module designed for voltage-free switching in applications requiring higher currents or voltages. Its simple installation makes it ideal for integration into control panels, offering reliable performance in fire alarm systems and similar setups where polarity reversal of outputs (such as bells or sounders) is necessary during alarm activation.
Thanks to its double-pole changeover contacts, this relay can handle significant electrical loads (5A @ 240V AC/30V DC), ensuring versatility in both industrial and emergency systems. A key safety feature is its polarised function, which requires correct polarity for activation—critical for fire safety compliance and avoiding false alarms.
Applications:
- Switching extra sounders in fire alarm systems
- Controlling emergency door releases
- General-purpose voltage-free switching in control circuits
Compact dimensions (50×30×70mm) allow seamless installation in tight spaces. Whether upgrading existing systems or implementing new safety measures, this relay provides a dependable and space-efficient solution for critical switching tasks.
