minutes (900 seconds), then the message will disappear 15 minutes after it is first turned on].

Press the HELP key twice again and the process will repeat itself. Note: This diagnostic only

indicates receipt of the correct polling address from the station. If there is a wiring problem from

the transmit line of the panel TX to the F1F2 subset, or a defective EIA (RS-232) portion of the

F1F2 subset, then the panel will still indicate an off-line condition in the central/monitoring

station.

If the APLEX control panel will not go on line, perform the following extremely effective test:

At the subset, unplug the cord labelled F1F2. The loop and carrier leds should extinguish. Check

for the following voltages as measured on the APLEX control panel's Comms/J terminal

strip:

F1F2 List 1 Subset F1F2 List 3 Subset

37 (-ve) to 39 (Tx) -0.5 VDC 37 (-ve) to 39 (Tx) 0 VDC

37 (-ve) to 40 (Rx) +10 VDC 37 (-ve) to 40 (Rx) -9 VDC(steady)

Plug the cord back into the subset jack labelled F1F2. Remeasure the APLEX control panel's

Comms/ J terminal strip:

F1F2 List 1 Subset F1F2 List 3 Subset

37 (-ve) to 39 (Tx) -0.5 VDC 37 (-ve) to 39 (Tx) 0 VDC

37 (-ve) to 40 (Rx) -5 VDC (pulsing +ve) 37 (-ve) to 40 (Rx) -9 VDC (pulsing +ve)

These measurements indicate that the F1F2 subset is functioning properly. Reconfirm with the

telephone company that the hub card leg is turned up (in service) and then request the alarm

company to set your control panel on line again.

PRINTING AND DVACS

(tm)

In this manual, reference has been made to the printing of the system log, on-line reports, etc.

Printing these items is not possible when the panel is set up for DVACS

(tm)

because the serial

port has been used with the DVACS

(tm)

data channel. To print a log, report, etc., lever up the

Comms/J terminal strip from the panel and remove it from the header pins. Prepare a printer

cable, complete with its own terminal strip, and press this terminal strip onto the panel header

pins (see page 54). This procedure will avoid the problem of incorrect re-installation of the

DVACS

(tm)

F1F2 subset. If you choose not to use a printer cable equipped with its own terminal

strip, then remove the signal negative (-ve) and TX and make the connections to the printer. Do

not leave the DVACS

(tm)

signal negative parallelled with the printer signal negative as this will

damage the F1F2 List 1subset. This is not a problem with the F1F2 List 3 subset.
