The Mobeye CM4400 is a combination of a 10y ltihium battery-operated Ei Electronics smoke detector and the Mobeye CM4410 communication module. In the event of an alarm, the loud siren sounds and the set contacts are informed via push message, voice call, SMS or e-mail. Works fully battery powered.

This product is the successor of the Mobeye CM2400.

Alarm messages

In the event of a fire alarm, the siren warns you with a loud signal on site. In addition, the contacts receive a notification by app (IOS/Android), telephone call (voice message), text message and/or e-mail. For the push messages there is a choice between an escalation plan or group message. With the escalation plan, the recipient can confirm the push message, so that the other contacts no longer receive the message. If none of the recipients confirms the push message, a phone call is made. The number of contacts is unlimited.
The Mobeye CM4400 can report fire and test reports to a private control room (ARC) for professional follow-up. Read more info.

Single smoke detector or multiple in a wireless network

The Mobeye Smoke Detector CM4400 is intended for situations in which one smoke detector (with reporting by telephone) is sufficient.
For situations with multiple smoke, heat and CO detectors Ei Electronics offers battery-operated detectors with wireless connection, such as the Ei650RF. A wireless relay module Ei413RF can be included in the Ei Electronics network; you connect the Mobeye CM4100 alarm dialer to the relay. As soon as one of the detectors in the network detects fire or CO, all sirens will sound and the communication module will send notifications.
Look at the infosheet for more combinations such as mains powered detectors.

Battery operated vs. external power

The CM4400 works on batteries. It can be used autonomously, anywhere. The Ei Electronics smoke detector has a 10-year lithium battery. The integrated communication detector works for more than a year on 2x CR123 batteries.
In order to use external voltage the power module AC-FA-EP is required. This accessory fits in the device and includes a country-specific mains adapter.
The combinations with the relay module and the CM4100 operate on external voltage. Due to the backup battery in the CM4100, a power failure can be sent as a notification.

Network and SIM card

The Mobeye SIM card gives the device full functionality, including the use of the Mobeye Internet Portal and the app. With the Mobeye SIM card, communication takes place over the 4G LTE-M network with 2G as fallback.
When you insert your own SIM card, the device works on 2G. Alarm messages are then sent via SMS and/or call to max. 5 telephone numbers.

Mobeye CM4400H Heat Detector

The Mobeye CM4400H and CM4400H-RF are equipped with the heat detector Ei603TYC and the Mobeye communication module CM4410. It has the same functions as the CM4400. Heat detectors are used in places where a smoke detector is unsuitable, such as in kitchens, bathrooms and garages.
