14.6 Keypad Speaker Operation

When using LCD Keypads, the panel provides distinct speaker tones from the keypad for Fire, Burglary,

Zone Monitor, and Prewarn events. The list below details the conditions under which the speaker is

turned on and off for each event.

Fire On - Fire zone alarm and Bell Output are ON.

Off - Alarm Silence or briey when a key is pressed.

Burglary On - Burglary zone alarm and Bell Output and is ON.

Off - Alarm Silence or briey when a key is pressed.

Zone Monitor On - One time only when a monitored zone is tripped.

Off - After one tone.

Prewarn On - During Entry Delay.

Off - When Entry Delay expires, when a Valid Code is entered,

or briey when a key is pressed.

14.7 Cross Zoning

Caution must be taken when cross zoning devices to ensure that the Cross Zone Time is long enough to

allow an intruder to trip both devices before it expires. A Cross Zone Time that is too short may allow an

intruder to trip the devices and allow only a zone fault report be sent to the central station.

When a Cross Zoned zone trips, a FAULT report is sent to the SCS-1R Receiver. When two Cross Zoned

zones trip within the Cross Zone Time, both zones send ALARM signals to the receiver. For example,

if zones 1 and 2 are Cross Zoned zones, and only zone 1 trips, a FAULT report is sent to the receiver

for zone 1. If zone 1 trips and zone 2 trips within the Cross Zone Time, an ALARM report is sent to the

receiver for zone 1 and zone 2.

Note: To operate correctly, all cross-zone zones need to be programmed as the same zone type.

14.8 4-2 Reporting to Central Station Receivers

This section of the XRSuper6/XR20/XR40 programming guide is intended to explain to installers, service

technicians, and central station personnel how the DMP 4-2 communication format operates and which

hexadecimal characters are sent for each system event.

4-2 Communication Format Configuration

The DMP 4-2 format communicates to the central station as 4-2 with a checksum at 40 pulses per second

(pps). The XRSuper6/XR20/XR40 panel using 4-2 communication will accept either a 1400Hz or 2300Hz

acknowledgment tone (handshake) from the receiver.

A report format sent to the receiver is dened as follows:

1234 56 7

aaaa f s c a = account number f = rst digit s = second digit c = checksum

4-2 Reporting Operation

When using the 4-2 reporting format, the panel follows this sequence to report to the receiver.

1. The panel dials the receiver phone number and waits for a response.

2. If the panel detects it is communicating with a 4-2 compatible receiver, all reports except those that

can only be sent in SDLC are sent to the receiver.

3. If the panel detects it is communicating with a DMP SCS-1/SCS-1R Receiver, all reports are then sent

in SDLC format.

4. If the panel last communicated to a 4-2 compatible receiver, a SDLC event cannot initiate a call to

the receiver.

5. If the panel last communicated to a DMP SCS-1/SCS-1R Receiver, any reporting event can initiate a

call to the receiver.

How to Read The 4-2 Communication Reports Table

The next page contains a table listing the 4-2 Communication Reports. This section explains how to read

that table.

The rst column on the left is the rst digit of the 2-digit event code sent to the receiver. The second

column is what that character represents.

1 2 ... 42 43 44 45 46 47 48 49 50 51 52
