Product description
Metra Locker Controller is used in different Metra Electronic Locking Systems. Device drives and
monitors Metra Electronic Locks. Up to 16 locks can be connected directly to the unit, with the
possibility to add up to two Extension Modules for 8 additional Electronic Locks each. This enables
configurations for up to 16, 24 or 32 locks, which makes the controller adoptable to many locker
layout configurations. As user interface different system specific Metra user interface devices (e.g.
Display RFID/Keypad/Combo/Touch, Reader Terminal, Reader Terminal Basic, etc.) can be used.

Page 4
