The C-250 has a Trigger Input for an external Postal Lock switch, or a Request to Exit (REX) switch. The switch must have a momen-
tary, normally open contact. Once the C-250 detects a contact closure on terminal positions 8 and 9, the door strike will be energized
for the amount of programmed Door Strike Activation Time. If the contact is still made after the programmed time is up, the C-250
will re-energize the door strike relay and go through another Door Strike timing cycle.
If DIP Switch 2 is in the ON position, the Trigger Switch input now controls whether or not the house phone will ring when the entry
phone goes off hook. If the Trigger Input is shorted, the house phone ringing will be skipped (Immediate Call Forward Mode), if open,
the C-250 will ring the house phone when the entry phone goes off hook. The touch tone command QQQ overrides the status of the
Trigger Input when DIP Switch 2 is ON.
D. Activating the Door Strike Relay
Anytime the house phone is connected to the entry phone, the tenant can actuate the door strike by entering the door strike com-
mand on their touch tone keypad. The C-250 determines if the touch tones are coming from the house phone or the entry phone and
only accepts commands from the house phone. Once a valid command is detected, the door strike relay will actuate for the amount
of programmed Door Strike Activation time. If an invalid command is entered, wait a few seconds and try again. The C-250 will wait
3 seconds after any touch tone entered to assure no more tones are coming, then it looks for a command match. The C-250 can be
programmed to handle either a 1 digit or 2 digit Door Strike Command (position #41). If a single digit is being used, the minimum
touch tone length is 100 milliseconds. During this time the C-250 must determine if the touch tone is coming from the entry phone
or the called party. If the C-250 is having trouble detecting touch tones from a remote phone because the tones are too fast, use a
2 digit door strike command. When using 2 digits, the touch tones can be as fast as 50 milliseconds, but the entry phone will be
dropped after the first digit is detected. The C-250 can then be sure that the touch tones are coming from the called phone.
E. Trigger Input

(satin dark brown powder paint

built-in color video camera. See DOD# 191.
On some Comcast lines, dialing a # when connected to the Central Office causes the CO to produce a short break in the line, appear-
ing to the C-250 as a command to ring the entry phone. This problem can be corrected by enabling the Comcast mode. In pro-
gramming, dial 1#52. With the mode enabled, the C-250 will quickly switch from the CO line over to the artifical line when the first
touch tone dialed is a #, allowing entry of # without ringing the entry phones. To disable the Comcast mode, dial 0#52 in program-
ming.
