Keypad Communication Supervision
Section [2] — Option [4]
Off = Disabled (default)
On = Enabled
Enable this option to monitor the communication between the control
panel and the keypad. If there is a loss of communication with the
keypad, the control panel generates an open keypad zone. This
option must be enabled on the control panel as well as the keypad
(enable "keypad zone supervision" on control panel section [090] key
[11] "on" for keypad zone 1, and key [12] "on" for keypad zone 2). For
this option to work, the keypad zone option [1] must be enabled.
Keypad Tamper Supervision
Section [2] — Option [5]
Off = Disabled (default)
On = Enabled
The keypad can be ordered with or without an anti-tamper switch. If
you want the system to supervise the status of the anti-tamper
switch, you must turn on option [5]. If the tamper switch is open, the
keypad will send the message "Keypad zone open". If you do not
have an anti-tamper switch or if you do not want the system to
supervise its status, turn off option [5].
Partitioning
Section [2] — Option [6]
Off = Disabled (default)
On = Enabled
This option must be enabled if the system that the 642BL keypad is
connected to is partitioned.
