Zone Connections
Zones 1 through 7 can be independently defined as normally closed, normally open or end-of-line resistor zones.
Zone 8 is always a normally closed zone.
For normally closed zones, a zone will go into alarm when a resistance of 2800Ω or greater is detected. Zone 8
will go into alarm when a resistance of 1000Ω or greater is detected.
For normally open zones, a zone will go into alarm when a 8400Ω resistance or less is detected.
For end-of-line resistor zones, a zone will go into alarm when the zone’s resistance drops below 2800Ω (a short
circuit). A zone will generate a trouble condition when the zone’s resistance rises above 8400Ω (an open circuit).
Zone Supervision using Zone 8
Zone 8 may be used as a 24-hour Zone to supervise all other zones; refer to the wiring diagram below for wiring
instructions.
The chart below provides the maximum wiring resistance for the various loops described above:
Zone 8 Zones 1 through 7
R1 + R2 = 500Ω maximum R5 + R6 = 500Ω maximum
R3 + R4 = 500Ω maximum R7 = 500Ω maximum
Bell Supervision using Zone 8
Zone 8 may be used to supervise a Grade A Bell as shown below:

Power-Up Procedure
Connect the transformer and wait approximately 5 seconds. Enter a few Keypad commands and activate a zone to
be sure that the panel and Keypad are responding to inputs. If the Keypad does not respond and no LED
indicators come on, check for AC voltage at the AC terminals. If there is 16 VAC present, check that the Keypad
