KC098 - 9V Battery Holder for use with SIT Remote Control System [ACS2 IR/RFT] (30106800310)
The ACS2 Remote System is operated by battery power with an infra red magic eye and handset. The system can be identified by the marking on the top of the black box - ACS2 -IR/RFT.
In some installations the battery pack may have been removed and replaced by a mains power adaptor and connection lead. The handset is delivered, fully tested, with a new battery, if you receive the handset and it does not work it is highly likely there is another fault on the system.x
