6 Reference & Installation Manual
keypad can then communicate the status of the zone to the control panel. A maximum of two keypad zones can be used with
each control panel. After connecting the device, the zone's parameters must be defined. For details on zone recognition and
Zone Programming on page 12. Also, refer to the feature Reassign Keypad Zone 2 on page 12.
Example: A door contact located at the entry point of an establishment can be wired directly to the input terminal of the entry
point keypad instead of wiring the door contact all the way to the control panel.
Figure 5: Keypad Zone Connections
When a 1641 LCD keypad is connected to the 1759MG, the Keypad Zone Sending option (Option [2] key [1]) determines
whether the status of the keypad zone will be transmitted to the control panel. The Keypad Zone Sending option of the
1641 keypad must be enabled during the following conditions:
If you are using both keypad zones and at least one is from a 1641 keypad.
If you are using the keypad zones of other types of keypads, such as a 1686H 10-zone LED keypad, and the
keypad zone definition of the 1641 keypad (keypad zone 1 or keypad zone 2; Option [2] key [3]) matches that of
another connected keypad.
2.11 Keyswitch Connections
Keyswitches allow users to arm or disarm a partition by pushing a button or by activating a
switch with a key. Connect the keyswitch (as shown in Figure 6) directly to the control panel
terminals. Once a keyswitch is connected, it must be assigned to a zone and its
parameters must be programmed (see Zone Programming on page 12 and Keyswitch
Options on page 17).
2.12 Fire Circuits
When a zone is programmed as a fire zone, the zone becomes normally open and requires an
EOL resistor. If a line short occurs or if the smoke detector becomes active, whether the
system is armed or disarmed, the control panel will generate an alarm. If a trouble occurs on a
fire zone, the Fire Loop Trouble will appear in the keypad’s trouble display (see page 42) and
the control panel can transmit the Fire Loop Trouble report, if programmed, in section [206].
2.12.1 4-Wire Installation:
Any on-board zone can be defined as a fire zone (see page 13) when using the 4-
wire installation. Connect the smoke detectors (as shown in Figure 7) directly to the
control panel terminals. Program the PGM with the “[
PG]/[FNC1] Key was Pressed”
Activation Event (see page 34) so the smoke detectors can be reset by pressing the
[
PG] or [FNC1] key. Pressing the [PG] or [FNC1] key will interrupt power to the smoke
detectors for 4 seconds (see PGM Delay on page 35).
It is recommended that all smoke detectors be connected using a daisy chain
configuration.
Do not place a jumper across the zone and
“BLK” input terminals of the keypads that
are not using their keypad zones.
