The Magnetic Reed Switch triggers an alarm when a transmitter is 
in the Exit Zone and the door is open. The Magnetic Reed Switch 
should be mounted at the top of a door near the non-hinged edge. 
It comes in two pieces: a switch and a magnet. The switch is 
mounted on the door frame; the magnet is attached directly to the 
door.

When normally closed (NC) reed switches are used on a double 
door, connect the switches in series. The provided Magnetic Reed 
Switches are normally closed (indicated with a gold Code Alert 
logo) when the doors are closed so that opening either door opens 
the switch on that door. The Magnetic Reed Switch detects when 
a door is open.

The CodeLock option is an electromagnetic lock attached to an exit and connected to the Exit Alarm 
Controller. If a transmitter is detected in the Exit Zone, the CodeLock activates to help stop the door 
from opening for as long as the transmitter is within range of the receivers. Refer to the CodeLock 
Electromagnetic Door Lock Installation Guide for information on installation and operation.
