Product information

Description

Commax MR-100R-S is an external alarm siren designed for outdoor use with intrusion and security systems. It delivers audible alarm tones and visual signaling to indicate breaches or emergencies, and is intended to be mounted on exterior walls or other outdoor structures. The device is compatible with common alarm control panels and aims to provide clear perimeter warning for both residential and commercial properties.

Advantages

The siren combines loud acoustic alerts with visible signaling to increase detection and deterrence effectiveness. Its weather-resistant housing allows continuous outdoor installation while maintaining functional electrical connections to a central alarm panel. The product is compact and engineered for straightforward wall mounting and wiring to typical security control units.

Suitable for

  • Perimeter protection of houses, apartments and small residential complexes
  • External signaling for commercial buildings, shops and offices
  • Integration with wired alarm control panels and security systems
  • Deterrence of unauthorized entry and rapid alerting of occupants and neighbors

When it may not be suitable

This external siren is intended to work with compatible alarm control panels that provide the necessary power and triggering outputs; it may not be suitable for systems without a matching wired interface or for standalone wireless-only installations. It is not a substitute for internal notification devices where indoor signaling standards or volume requirements differ.

Key specifications

  • Intended installation: outdoor wall mounting
  • Functions: audible alarm tones and visual indication (strobe/LED)
  • Compatibility: designed for connection to standard wired alarm control panels
  • Housing: weather-resistant enclosure suitable for exterior use
  • Mounting: surface-mounted on exterior walls or vertical surfaces

How to use

Mount the siren on a secure exterior surface at a height and location that maximizes audible and visual coverage while remaining accessible for wiring. Connect the device to the alarm control panel following the panel manufacturer’s wiring diagram and the siren’s polarity and power specifications. After installation, test the unit using the alarm system’s output test function to verify sound and visual operation, and seal cable entry points to maintain weather protection.

What to consider before purchase

  • Ensure your alarm control panel provides the correct wired output and power for an external siren
  • Verify local regulations on outdoor alarm sound levels and permitted signaling devices
  • Confirm mounting location is sheltered from direct water ingress and allows secure cable routing
  • Check that the audible level and visual indication meet your site’s deterrence and notification needs

Usage recommendations

Place the siren where both sound and light are unobstructed by surrounding structures; perform regular tests and visual inspections, and use corrosion-resistant conduit or grommets for cable entries to prolong outdoor reliability.
