Each Zone on the panel that is configured for Standard Conventional mode must have the intelligent end of line module (EOLM-1) fitted to continually monitor each zone for the presence of fault conditions such as detector head removal, open or short circuit and for end of line failures even when in a Fire condition. The EOLM-1 module can be placed into the base of the last manual call point or detector base.- Full end-to-end authentication and encryption: This prevents non-authenticated sensor inputs communicating unencrypted with controllers.- Field upgradeable code with plug and play authentication for quick and secure installation: This makes it easy to upgrade the code or authenticate the sensor without having to disturb the installation.- Small form factor for an easy install into almost any sensor: This makes it easy to install into a wide variety of sensors.- Increased security: The ELM provides a higher level of security by preventing unauthorized access to the system.- Weight 20g- For conventional fire alarm circuits
