DGM INSTALLATION AND MAINTENANCE MANUAL
44 700135-0000 Rev. O
Each keypad is assigned an Entry Zone, which is any zone on the DGM panel. The
keypad is then able to ARM or DISARM. It is possible to assign any or all (16) keypads to
the same Entry Zone. All keypads that are assigned to the same Entry Zone will display
the same information, and any keypad assigned to a zone can ARM or DISARM that
zone.. For example, if Keypad #1 is ARMED, all of the keypads assigned to the same
Entry Zone as Keypad #1 will also be ARMED, and, will display a steady RED LED.
5.5.1 EXTERNAL KEYPAD INDICATORS
The keypad provides 12 (0 through 9, #, and *) buttons, RED and GREEN LED, one
Form C relay output, and an audible beeper. The Form C output has no defined function
at this time, but can be instructed by the DGM panel when to turn on and off at a future
date.
When an external keypad is first attached to an DGM, but before it is activated (Function
29), the GREEN and RED LEDs alternately blink. This indicates a Data Link down. The
same thing occurs whenever the communications link is broken between an external
keypad and the DGM.
Each keypad is capable of having 250 programmable, four-digit PIN numbers, which can
be changed at the DGM panel, or downloaded from the Maintenance shop PC computer
via the SYSTEM 3505 PRISM LX. The 250 PIN numbers will reside in the keypad.
NOTE: If the GREEN LED is BLINKING, a PIN number will not be accepted at the
keypad.
5.5.2 DISARMING OPERATION
When a Security Entry Zone assigned to a keypad is violated, the DGM begins an entry
delay, which has been programmed from one to 90 seconds. At the same time the beeper
begins to beep (one pulse per second) and the RED LED flashes. The same response
occurs at all keypads assigned to the same Entry Zone.
If a valid PIN number is entered, the beeper will stop, the RED LED turns off, and the
GREEN LED turns on. The DGM then reports an opening to the head end equipment. If
the entry point remains open after a valid PIN number is entered, the GREEN LED will
start to blink. It will continue to blink indefinitely until the entry point is secured.
If an invalid PIN number is entered, or if no PIN number is entered within the allowable
time delay, an ALARM is sent to the head end, the beeper beeps at the rate of three
pulses per second, and the RED LED remains illuminated without flashing. The same
response occurs at all keypads assigned to the same Entry Zone.
If a valid PIN number has not been entered, 30 seconds after the ALARM is sent the
keypad will beep once every five seconds until either a valid PIN number is entered, or the
operator disarms the zone. The activated zone in ALARM will not change state unless the
zone is disarmed at the keypad or by the operator.
5.5.3 ARMING OPERATION
Prior to arming, the desired Entry Zone must be secured. A steady GREEN LED indicates
that the Entry Delay Zone is secured; a flashing GREEN LED indicates that a zone under
the control of the Entry Delay Zone is not secured. If the GREEN LED is not on at all, then
