Pushbutton Connections
Any channel can be configured as a pushbutton control input to allow the operator to
control the operational sequence if the input card is being used with P925TS-O Output
Cards.
There are seven pushbutton control inputs available:- Lamp Test, Acknowledge,
Reset, Silence, System Test, First Up Reset and Combined Lamp/Audible Test.
Pushbuttons connected to the associated Input should be of the momentary, non-
maintained, type with one Normally Open contact per pushbutton.
The common return of the pushbuttons is no24VDC however as pushbuttons
use standard digital input channels the common return will always be at the same
voltage level as the alarm inputs (24VDC as standard optionally 48VAC/DC,
125VAC/DC or 250VAC/DC.
Example:- A system that requires Test, Acknowledge and Reset Pushbuttons would
be factory supplied with pushbutton inputs available on channel 14, 15 & 16 on the last
P925TS-I Input Card within the system,.

Input Card with channels wired as pushbutton inputs the associated outputs would
only be active when the pushbutton is pressed.
