Preventing the two pulses on the siren when Away Armed
By default, the external siren output gives two pulses when the security
system is armed to Away (or Vacation) to provide confirmation of the
armed state. In some installations, this may be undesirable. To disable
this sound, refer to Worksheet Table 25 (output settings) which show
how to program siren types to be heard on the keypad, Siren (Bell)
output and Door Station. Siren Type 5 is the Away Armed siren type,
which is output to the Bell output. To disable this, do not add the value
corresponding to the Bell (Siren) output. For example, to hear the two
pulses on the keypad and Door Station only, program 64+32 = 96 at
the Location given
Changing the Siren duration for any Alarm
When an alarm occurs, the siren turns on for the programmed time,
depending on the alarm type. These settings can be found in Table 19 ,
22 and 24. The siren type assigned to each Alarm type can be found In
table 19, The Duration for each Siren Type can be found in Table 22.
For example, the Intruder Alarm uses Siren Type 1, which has a default
duration of 5 minutes. To change this to 10 minutes, look up Siren
Type 1 in Table 22. The duration in seconds is contained in two
locations . The default values are for 300 seconds. To change this to
600 seconds, or 10 minutes, refer to Table 24. For 600 seconds, the
1st location is not important, but the second location should be set to
46. The Locations menu is accessed in Engineer Menu 7,4,1
Time Correction
(from Version: 4.87, Location 1846)
Comfort’s built-in real time clock is accurate to within 5 seconds a day,
but temperature changes may cause further errors. For Time Program
operation, it may be important to have the clock be more accurate than
this. This time error can now be corrected on a daily basis. Location
1846 contains the time in seconds which Comfort will use to adjust its
own clock. By default, this location is programmed to zero. To speed
up Comfort’s clock, program a value of 1 to 29 in this location. To slow
down the clock, program a value of 30 to 59 in this location. For
example, if Comfort is slow by 5 seconds every day, program 5 into
Location 1846. If Comfort is fast by 5 seconds each day, put 55 into the
Location. If the clock is slow by 20 seconds every day, put 40 into the
location. To slow down the clock by up to 30 seconds, subtract the time
in seconds from 60. The range of adjustment is from +29 seconds to
-30 seconds. The time adjustment takes place at a fixed time each day,
at 3 AM.
Follow this procedure to get the best results for time correction. Set the
clock exactly according to an accurate time reference (the recorded
time announcement from the telephone company is a good source).
Change the time using the keypad Program Menu 2 ( Change Time and
Date), 2 to change Time. Enter the time in hour, then minutes. When
you press # to enter the minutes value, the seconds value is set to 00.
Synchronize pressing of # for the minutes value with the recorded
