4193SN Serialized Interface Module (SIM) The 4193SN is a serialized two-zone expander used to connect alarm sensing devices to controls which support serial number polling loop devices (i.e., Vista40, Vista-50P, and Vista-100). The 4193SN can be configured as one supervised zone (10K EOLR) and one unsupervised zone, or two unsupervised zones (normally closed devices only). Consult the control panel installation instructions for programming information.

For Fire Applications: The 4193SN must be mounted inside the control panel cabinet or inside a ULListed junction box. Loop 1 must be used in the supervised configuration for Fire. Loop 2 may be used for Burglary.

For UL Burglary Applications: If using an unsupervised zone of the 4193SN, the unit must be mounted within 3 feet of the alarm initiating device, with no intervening barriers.
