2.2.4 Door lock connection
Door lock connections depend upon the type of lock used (i.e. electric
door strike or mag lock) and surrounding mounting surface (i.e. wood,
sheetrock, cement, glass, etc.).
Be sure to distinguish between the positive and negative terminals on
both the S900 and the door lock. The unused bare end of the wire should
be cut off and wrapped in insulating tape. Note that the time-delay of the
door locks is usually adjustable.
Selecting door lock
For glass doors which swing both in and out, we recommend the use of
electro-magnetic door locks (aka “mag locks”).
For 1-way opening non-glass doors we recommend the use of electric
door strikes, instead.
While both locks are equally secure, the mag lock is considered safer
than the electric strike, especially during power interruptions. During a
power failure caused by fire or other safety threats, the mag lock will
“fail open” and allow people to exit a room/building unhampered.
Conversely, the electric strike “fails closed”. In the event of a power
failure, it is possible to exit a door secured by an electric door strike
provided there is a mechanical device (i.e. door handle or exit bar) to
free the door during power interruptions.
