The DALMx000 is a versatile communication device primarily functioning as an external dialer and/or IP converter for fire and burglar alarm systems. It ensures secure alarm transmission, primarily via fixed Internet and secondarily through GPRS/3G. The device is designed to operate reliably even in low reception conditions, with GPRS/3G links maintaining functionality down to a signal strength of 6 (out of a maximum of 31). For optimal performance during installation, it is recommended that all LEDs are lit, indicating a signal strength of 12 or more.
Function Description
The DALMx000 offers multiple alarm notification methods, including SMS, E-mail, and IP alarms. It can be programmed with up to 10 or 12 (for DALM5000) different SMS, E-mail, or IP alarm receivers.
The device features eight hardwired inputs for direct connection to alarm sensors or relay outputs from fire alarm systems. These inputs are activated via potential-free closure to or opening from system ground, configurable during programming. Each input can be independently connected to specific receivers and assigned event codes.
In addition to hardwired inputs, the DALMx000 includes five "virtual inputs" that automatically activate in response to system events such as power supply issues (below 10.5 VDC), Internet connection errors, GPRS/3G connection errors, bypass activation, and cover protection. These integrated inputs are connected to receivers similarly to hardwired inputs and can have separate activation delays.
A key feature is its "dialer capture" functionality. The DALMx000 can simulate an analogue telephone line and alarm receiver, receiving alarms from existing alarm systems in SIA or Contact ID format. It then converts these into encrypted alarm messages and sends them via TCP/IP to alarm receiving centers. For Contact ID alarms, an acknowledgment tone is sent to the dialer only after the IP alarm is acknowledged by the alarm receiver. If the dialer hangs up before acknowledgment, message parameters are stored in an internal queue and processed upon subsequent dialer attempts. For SIA alarms, acknowledgment is sent as soon as the alarm is correctly received by DALMx000, with output REL1 activating for two seconds if transmission to the alarm center fails.
The DALMx000 can also emulate an analogue modem, allowing connection to the built-in modems of alarm systems like GE NX Series, DSCs Power Series, and Bosch 72xx/74xx Series. This enables remote connection for uploading and downloading via fixed Internet or GPRS/3G using the respective company's standard software.
Alarm notifications via TCP/IP are received by alarm receiving centers equipped with a standard SIA DC09 receiver or Dualtech's IPEagleCMS software. The device is typically powered from the existing alarm system and housed in a plastic enclosure or mounted within an existing system enclosure.
Alarm Transmission Procedures:
Alarm transmission is triggered by:
- Activation of any hardwired input.
- Activation of internal error checks (e.g., GPRS/3G error).
- Reception of dialed alarm notifications in Contact ID or SIA format from a connected analogue alarm dialer.
- Activation of alarm from equipment connected to the DALM serial port(s).
IP Alarm Procedure:
The device attempts transmission through multiple paths, testing each four times:
- Primary receiver via fixed Internet.
- Secondary receiver via fixed Internet (if primary fails).
- Primary receiver via GPRS/3G (if fixed Internet fails).
- Secondary receiver via GPRS/3G (if primary GPRS/3G fails).
- Second attempt to primary receiver via fixed Internet.
- Second attempt to secondary receiver via fixed Internet.
- Second attempt to primary receiver via GPRS/3G.
SMS Type Alarms:
DALMx000 can send SMS alarms via the GPRS/3G module to any mobile number. The message includes Object ID, Input label, and Input text. For analogue alarms, event code, area, and event text are also added. This feature is not available with Dualtech SECURE SIM, where messaging is handled via the EasyWebManager web portal.
E-mail Alarms:
E-mail alarms can be sent via both fixed Internet and GPRS/3G. The e-mail includes Sender ID, Object ID, Input label, and Input text. Similar to SMS, analogue alarm details are added if applicable. This feature is also not available with Dualtech SECURE SIM.
