Main Features:

  • Available Communication Channels:
    - CAT-M1 (on 4G infrastructure)
    - NB-IoT (on 4G infrastructure)
    - GPRS 2/2.5G (fall-back option)
    - IP (10/100 Mbs Ethernet)
    - WiFi (4 different channels)
    - PSTN Dialer (Contact-ID format)
  • Dual-SIM models feature two SIM cards, enabling the unit to connect to a second GSM carrier in case the Primary carrier communication path fails.
  • All models feature 8 dry-contact Inputs + Tamper input, each programmable for its Event Code, Polarity, Sensitivity. Optionally, the first 6 inputs can be programmed for End-of-Line Resistor protection.
  • Monitoring of Power Supply Input (Mains AC power monitoring) and Battery Voltage (including Battery test under Load). Reporting on AC status, Battery Low & Battery Missing.
  • Extended operation voltage range: 8-28 VDC (compatible with 24V Fire Alarm Panels).
  • Simple Alarm Panel functionality - the inputs can be programmed for Alarm Zones property, e.g. Immediate, Delayed, Follower, 24-Hour, Silent type. One input can be designated as an Arm/Disarm Key Switch input. Outputs are used for Siren and Alarm System Status monitoring. The unit can be optionally remotely Armed/Disarmed from the Central Server.
  • Universal Alarm Panel Interface (in "P": models), connects to all types of Alarm Panels on their Tel. Line Input and retransmits all the Events via the GPRS channel (Contact-ID format only).
  • Option: 4 Outputs for internal state monitoring and Remote Control:
    - 1 Change-Over dry contact Relay
    - 3 open-collector, 1 Amp. Max.
  • 5-Level GSM Signal Strength indicator (RSSI).
  • Connected Network type indicator LEDs – GSM/IP-WiFi/Connection via SIM1 (GSM Provider 1) / SIM2 (Provider 2).
  • NEW: Programming the unit from any standard Internet Browser, from any PC or Smart-Phone that connects to the Internet: by default, the ComSec-2000 connects to a special Server with Web interface service. It can then be identified by its unique SIM card serial number (IMEI) or the MAC address on IP channel, and then re-programmed from any device with WEB access, such as a hand-held Cellular Smart-Phone. In addition to programming, the technician can then check the proper function of the unit, including the RF reception level at the site (RSSI).
