Xantech DCH4 Door Strike Activation Time, Caller ID, Entry Phone Ring Cadence

G. Door Strike Activation Time

A single pole double throw relay is available for each entry phone (a second set of contacts are available on solder pads only), and each may be programmed with its own “doorstrike” activation time (programmed in seconds). Each time must be 2 digits (Example: 00 = 1/2 sec.) and is stored in locations #19, #29, #39 and #49 for relays 1 through 4 respectively. All activation times are factory set to 00 (1/2 sec.)

Note: A buzz sound will be heard in the house phone and entry phone, indicating the door strike relay has been activated and visitors can now open the door.

H. Caller ID

The DCH4 is factory set to send “Caller ID” and “Call Waiting Caller ID” information from the entry phones. If “Caller ID” is not required, enter “*2” while in programming to disable the DCH4 from sending “Caller ID” and “Call Waiting Caller ID” data to the house phones. Enter “*1” to enable “Caller ID” and “Call Waiting Caller ID” data (see Operation section A).

I. Entry Phone Ring Cadence

Entry phone calls are factory set to ring the house phones in a custom double ring cadence (.7 seconds on/.3 seconds off/.7 seconds on then 4 seconds off between rings), “*3”. The DCH4 can be programmed to give a standard ring cadence for entry phone calls (2 seconds of ring, and 4 seconds off between rings), enter “*4” when in programming. Entry phone ringing can also be disabled

by entering “0#62”. This is useful when connecting the DCH4 to the DPC100 to provide unique front and back door chimes.

J. Outside Line Access

1.Dial “9” to Access the Outside Line - To program the DCH4 for C.O. dial tone, enter “*5” while programming. To gain access to C.O. dial tone, dial a Touch Tone “9”.

2.Instant Outside Line Access (factory default) - To program the DCH4 for private dial tone, enter “*6” while programming. House phones will instantly have the outside line dial tone on an off-hook.

K. Maximum Entry Phone Ring Count

The number of times an entry phone call will ring the house phones can be limited in programming. The programmable maximum ring count must be 2 digits and is stored in location “#61”. The maximum ring count is programmable from 1 - 99 and factory set to (05) 5 rings.

L. Doorbell Switch Input and Auxiliary Contact Output

1.Doorbell Mode (DIP Switch 1 ON - factory setting)

With the DCH4 in the doorbell mode (DIP switch 1 ON), a normally open switch (SPST 6-16V lighted or non-lighted doorbell button, etc.) can be connected to terminals 26 and 27 (DOORBELL SWITCH / AUX INPUT). This switch should be located near entry phone 1. Door chime power (normally connected to a doorbell button) can be routed through terminals 28 and 29 (N.O. AUX CONTACT OUTPUT). A momentary closure on the DCH4 input terminals will momentarily activate the AUX CONTACT OUTPUT terminals for the same duration, activating your door chime. Entry phone 1 will be called, automatically answer (see the Technical Practice for your entry phone) and begin ringing the house phones (terminals 4 and 5 LINE OUT TO PHONES). The house phones can then be answered, doorstrike commands entered, etc. (see Operation sections A-E).

Notes: Entry phone 1 ringing the house phones can be disabled in this doorbell mode, if it is desirable to have the doorbell chime but not the house phones ring. This option can only be used if
