DRY CONTACT

TRANSISTOR OPEN COLLECTOR OUTPUT
A dry contact means that no electricity was connected to it. It is prepared for free connections. The Relay
Output contacts provided in this keypad system are dry contacts.
Normally Closed, the contact is closed circuit at normal status. It is open circuit when active.
Normally Open, the contact is open circuit at normal status. It is closed circuit when active.
An open collector output is equivalent to a Normally Open (N.O.) contact referring to ground similar to a relay
contact referring to ground. The transistor is normally OFF, and its output switches to ground (-) when active.
The open collector can only provide switching function for small power but it is usually good enough for
controlling of an alarm system. The Duress, Inter-lock, Key Active Outputs of the keypad are open collector
output.

(F) OUTPUT 3
(WHITE/RED WIRE)
Output 3 is an open collector output prepared for
auxiliary controls. It may be used for arm-disarm
of a security system, enable and disable of a
keypad or a protection zone etc.; it can also
drive a relay to give full function of N.C. and N.O.
outputs as like the output 2 making the keypad a
ture 3 output system.
