4.7.1 Siren Pre-Installation
Installation of the Siren and Light Interface Module with a Cencom Sapphire siren requires
interface kit IK-A1. Customers who have not already purchased a 2-port internal
expansion board from Whelen may choose to have one included in their interface kit by
purchasing version IK-A1WB which will include the OEM expansion board. The expansion
board will install inside the Sapphire amplifier and add 2 additional ports necessary for
third-party communication.
Interface Kits:
DATA-A cable, Audio-1 cable
DATA-A cable, Audio-1 cable, 2-port Internal
Expansion Board
4.7.2 Data Connection
The DATA-A cable provided in interface kit IK-A1 allows the Siren and Light Interface
Module to communicate with the siren. Connect the one side of the DATA-A cable to the
Siren and Light Interface Module port labeled SIREN-A. Connect the other side of the
DATA-A cable to the Sapphire siren amplifier port using one of the two expansion ports.
The Siren and Light Interface Module port labeled SIREN-A should never
be connected to the CTRL HEAD ports of the Sapphire or damage to one
or both devices might occur.
