9940/9941 Keypads A B C D Installation Guide
Introduction The 9940 and 9941 keypads are designed to work with 9853, 9851, 9752, 9751 and 9651 alarm system control units. These keypads are a direct replacement for the 9930, and offers the advantage of smaller size and improved appearance. The 9940 keypad has a proximity tag reader coil fitted inside the case and can work with the same proximity tags as the 934 proximity reader module. The 9941 has no detector coil fitted.

Installation Cabling Keypads Cooper Security recommend that you use 8-core 7/0.2 or 16/0.2 alarm cable for wiring keypads You can connect the keypads in either a star or bus configuration. If you are intending to use long cable runs then Cooper Security recommend that you use star wiring with no more than 200m of cable per branch. Siting Restrictions (9940 only) The 9940 keypad contains a coil inside the case that acts as the sensor for proximity tags used to set and unset alarm systems.
