detection with the link ‘ON’ or ‘OFF’. Always remember to have the link on so it can communicate with the
Securityguard.
Tamper Button.
When the plastic housing is lifted a tamper alarm message is sent. A low level warning will sound in disarm or
home mode. A full alarm will sound if in armed state.
Sensitivity Control (VR1)
The sensitivity control is used to adjust the sensitivity of the vibration sensor (Nessensor). This control (Low =
full anti-clock wise, High = full clock wise) can be used in conjunction with the sensitivity settings on the
Nessensor itself. (High, Medium, Low) If a vibration sensor is not used have the sensitivity set to low. (full
anti-clock wise)
Important: Care should be taken when handling the circuit board as the reed switch is quite fragile.
Incorrect handling may damage the vacuum seal of the reed and cause short and long term intermittent
operation.
7. DIALLER
The dialler will report alarms to a monitoring center and is also capable of remotely programming the Medi
Alarm via a modem link.
7.1 REMOTE PROGRAMMING
The Medi Alarm may be remotely programmed via a telephone modem link. Remote programming is enabled
when in Medi Alarm is in program mode and may be enabled in ‘NORMAL’ mode by setting the program
option.
Medi Alarm may be installed in parallel with answering machines, faxes etc. which will all answer the phone.
Medi Alarm uses an answering technique called fax defeat. Fax defeat is done by calling the panel, hanging up
and calling back. The panel will answer the phone as soon as the call back ring is detected .
All program options may be remotely programmed.
Medi Alarm will remain on line for 4 minutes while communicating with modem. This ensures
communication failures will not leave Medi Alarm in program mode.
7.2 ALARM REPORTING
This reporting is used to transmit alarms from a subscriber’s site to a monitoring center via the telephone.
There are 2 phone numbers, a primary number ‘N’ and a secondary number ‘n’. Reports are usually sent on
the primary number but if the dialler is unsuccessful in connecting, it will dial the secondary number.
Telephone numbers ‘N’ and ‘n’ must be programmed into the Medi Alarm’s memory.
A client account number is allocated by the monitoring company to identify the customer. The client account
number must be programmed into the Medi Alarm’s memory.
Time till first test call option allows test calls to be sent to monitoring during non peak periods (usually at
night.) This time is only used when exiting program mode. The first test call is made in the time specified by
program option ‘TIME TO FIRST TEST CALL’. All test calls are then made at intervals specified by program
option ‘TEST CALL TIME’. ‘TIME TO FIRST TEST CALL’ option should be programmed.
The dialler reports alarms to a central monitoring station in Ademco High Speed format.
New alarms initiate a dial out report. Alarms are deemed to be restored when the ‘CANCEL’ button on the
Medi Alarm is pressed.
