The CR-11 is an extending output module which provides additional functions for Jablotron car alarms CA-10, CA-320 and CA-180x. The module can be used for central-locking control, immobilization, an additional siren, a wireless pager, powered window remote control, etc. It has two built-in relays, each with a 15 Amp switch-over contact. The functions of the relays are selectable by the DIP switches inside each CR-11. The module receives data from the car alarm via a single wire (digital communication). Up to four CR-11 units can be connected to each of the above Jablotron car alarms. etc. The older CR-11 module can be combined with the CR-11A.
