• Contact Debounce Time

(Loop Response) 7050 & 7750/UL only: Programs a debounce

delay for the zone inputs of 7050 and 7750/UL subscriber units to

prevent input switches or relays from causing nuisance alarms and

repeated reports of the same alarm. The default setting is 0.12

seconds. If you choose to change this setting, simply enter the new

value and press <Enter> to move to the next field. A control unit

(panel) output(s) to the 7750 RF subscriber unit shall be

programmed to latch in when it triggers a zone input on the

7750.

Note: The contact debounce time in the 7050-E, 7440, 7450, 7750-

F4x4 and 7750-F8 units are preset at 0.12 seconds and cannot be

changed.

• Acknowledgment Delay: If a subscriber unit does not receive

an acknowledgment (Packet Acknowledge) within the time

parameters set by the Acknowledgment Delay parameter, it

activates an output to annunciate the problem locally. The next

successful communication to the central station will include an

ACK Delay fault code. The default setting for this feature is 90

seconds. If you choose to change the ACKknowledgment DELAY

period, simply type in the new value. Click [OK] to complete and

send your timing parameter data.

For 7750/UL, 7750-F4x4 and 7750-F8 Subscriber Units: A

zone of the control panel shall be connected to the relay labeled

"ACK DELAY", to monitor the subscriber unit against antenna

removal, communication failure and to provide a local and remote

annunciation of such a fault condition. (Refer to subscriber

manuals.)

NOTE: For all remote program functions, watch to make sure that

a data confirmation packet is received from the target subscriber

(watch scrolling message screen area).
