Wireless Solar Siren HmIP-ASIR-O
Homematic IP represents a complete revolution in the field of Smart Home, bringing you uncompromising German quality, comprehensive solutions and wide modularity, including a portfolio of products designed to secure and protect buildings.
The Wireless Solar Siren (HmIP-ASIR-O) is designed for outdoor use and is part of the Homematic IP smart home system. It enables reliable acoustic and visual alarm signalling. For this purpose, the siren has two powerful piezoelectric speakers with an intensity of 100 dB and five highly luminous LEDs, which are housed in a weatherproof enclosure with IP44 protection class.
Use
Sirens are an essential part of an alarm system. They reliably alert you to danger, scare off intruders and attract attention. The siren (HmIP-ASIR-O) takes less than two seconds to activate a strong alarm and bright LED indicators in response to the alarm signal.
The alarm can be triggered, for example, by a breach of the space monitored by the motion sensor or by a window or door under the protection of the Homematic IP Window and Door Sensor (HmIP-SWDx). In this case, the siren will sound an alarm and you will be informed of the event via push notifications from the Homematic IP mobile app on your smartphone.
Solar power
Thanks to the sustainable power supply via a powerful solar cell in conjunction with a replaceable NiMH rechargeable battery, no other alternative power source is required for the operation of the outdoor siren, yet the siren is equipped with a backup micro USB port for power or battery capacity recovery. Battery power ensures reliable operation even at night or on days with no solar activity. The siren requires minimal maintenance and offers adaptable use.
System status indication
The alarm mode activation and deactivation tones are quite useful. A short beep from the siren buzzers reminds users that the premises are guarded and the exit delay is active. The risk of an unwanted alarm is thus significantly reduced.
The use of the siren is widely configurable. You can select the duration of the audible alarm (3 – 6 minutes) and the choice between different audible alarm tones.
However, acoustic tone may not be desirable for all types of scenarios and applications. For this reason, the acoustic tone can be deactivated in Homematic IP and only the optical signaling can be set. Again, the user has a choice of 4 LED signaling effects, so the user can choose the appropriate signaling method depending on the nature of the alarm.
Signalling settings
The siren has 9 different alarm tones that can be freely configured depending on the alarm input defined by the added Homematic IP smart home element. For example, alerts for building intrusion, fire danger, flooding of the monitored area, etc.
Protection in case of sabotage
If an intruder gets to the siren, the tamper contact reliably detects the tampering and triggers an alarm. Inter-instrument communication ensures that the alarm is triggered even without an Internet connection. Even in the event of sabotage or destruction of the Central Unit (HmIP-HAP), the siren remains in alarm mode.
System operation
The wireless connection of the Siren (HmIP-ASIR-O) to the Central Unit (HmIP-HAP) offers convenient setup and control of the comprehensive Homematic IP smart home system using an intuitive app (for Android and iOS in CZ) designed for smartphones. The mobile app enables instant response to messages and alerts from your smart home system and connects all Homematic IP devices via a free, unlimited cloud that allows you to set up and control the system from anywhere in the world, transfer important information and update the software and firmware of the devices, and forward configuration and operational commands from the Homematic IP app to individual smart home devices.
Easy installation
Thanks to the solar and battery power supply, the alarm siren can be installed even in hard-to-reach places without the need for additional wiring. An integral part of the siren is a bracket for quick and easy installation.
HomematicIP communication protocol
For safe, stable and reliable communication, the system has its own unique radio technology at the operating frequency of 868.0 – 869.525 MHz with fully encrypted AES-128 communication. Operating on this frequency limits wireless transmissions to 1% of the clock time, ensuring long battery life for connected devices and users are not exposed to continuous wireless radiation. In addition, the central unit (HmIP-HAP) reliably detects radio interference.
