Transmitter supervision windows

LCD touchpads will display instructions when accomplishing tasks.
To change the transmitter supervision windows, do the following:
1. Enter * 8 at the keypad. On LED touchpads, the five func-
tion lights start flashing.
2. Enter the program code (factory default is 9 7 1 3).
3. Enter the DIP switch setting module number and press #.
On LED touchpads, the Armed LED turns on to indicate the
control panel is waiting for a programming location entry.
4. Enter 195 # to enter location 195, segment 1.
5. Enter the new normal supervision time (0 to 255 hours) and
press *. If you choose 0, the normal supervision window is
set to 256 hours.
6. Enter the new fire supervision time (0 to 255 hours) and
press *. If you choose 0, the fire supervision window is set
to 256 hours.
7. Enter the new short supervision time (up to 30 minutes).
The short supervision time prevents arming if a transmitter
has not checked in within the set time. This applies only to
specific countries outside the US. Check the control panel
installation manual to determine if this setting is available.
If you enter a number higher than 30 (the default value is
40), you disable the feature.
8. Press * to save any changes. The panel waits for the next
location entry.
Note: If you press #, it does not save changes to the current
segment, but it does save changes made in previous
segments.
9. To exit program mode, press EXIT EXIT.

Delete transmitters

LCD touchpads will display instructions when accomplishing tasks.
The following section describes how to delete transmitters from
the receiver.
Note: This procedure makes the receiver ignore a transmitter, but
does not remove the transmitter identification from the
receiver’s memory. The transmitter can be reactivated by
turning segment 1 on zone back on, or a new one can be
learned into the zone.
To delete transmitters, do the following:
1. Enter
* 8
at the keypad. On LED touchpads, the five function
lights start flashing.
2. Enter the program code (factory default is 9 7 1 3). On LED
touchpads, the service light flashes and the five function
lights change from flashing to on steady.
3. Enter the DIP switch setting module number and press #.
On LED touchpads, the Armed LED turns on, indicating the
control panel is waiting for a programming location entry.
4. Enter the zone location number to be deleted and press #.
On LED touchpads, the Armed LED turns on and the Zone
LEDs display the binary data for the current settings.
5. To change transmitter feature 1 (enable sensor), press 1. On
LED touchpads, the 1 LED turns off to indicate the feature
change and the Ready LED flashes to indicate the change
request.
6. Enter * #. On LED touchpads, the Ready LED stops
flashing to indicate the new settings are stored in memory
and the system automatically exits from that location.
7. To continue deleting transmitters, repeat steps 4 to 6.
8. If you want to delete all transmitters and load factory
defaults, enter 9 1 0 #.
9. To exit program mode, press EXIT EXIT.
Testing and troubleshooting
Test all transmitters to verify programming and operation. Use
location 200 to troubleshoot transmitters mounted in marginal
signal strength locations or if the panel has a sensor lost trouble
condition. To troubleshoot the transmitters, do the following:
• Delete the transmitter and relearn it back into the receiver.
• Go to location 200 and check the signal strength. A signal of
6 or more indicates good signal strength, anything less
could cause periodic sensor lost trouble conditions.
• If signal strength is below the acceptable level, delete the
transmitter and rotate the mounting position (90, 180, or 270
degrees).
• Relearn the transmitter into the receiver and check location
200 for signal strength.
• If rotating the mounting position does not improve signal
reception or is not practical, move the transmitter to
different locations near the desired mounting area.
• Delete and relearn the transmitter until an acceptable signal
level is attained, then mount the transmitter.
CAUTION Do not set the normal or fire supervision
windows to 1 hour. This causes false trouble
reports from all learned wireless transmitters.
