THE POWER LED ON THE No. 1021/4021 SHOULD BE LIT AT ALL TIMES. If out, A.C. failure is indicated and the
system is operating on battery. Check plug-in transformer or for power failure (or call serviceman).
IMPORTANT: Wait at least 5 seconds between successive attempts at arming or disarming with the No. 5240 or it
will not be possible to successfully enter the next disarm/arm code. Exception: The 5 second wait can be
eliminated by keying any digit not used in the 4 digit code and then the code.
To -Arm Burglary System :
1. Make sure the A.C. POWER LED is lit.
2. If remaining on premises after arming, the Interior Zone (see 4 below) and ENTRY DELAY may be turned OFF
if desired.
Note: The Interior Zone may not be turned OFF after arming (although turning it ON is permissible). The ENTRY
DELAY may betumed OFF only while the system is armed. It is turned ON by subsequent operation of the
ENTRY DELAY (INSTANT) switch or automatically at arming time.
3. The GREEN Loop Status LED on the No:5240 should be Iii to indicate that the Perimeter, Interior and Entry/Exit
(Delay) Zones are properly closed and the system is ready for arming.
If the Loop Status LED is NOT lit, check the ZONE STATUS LEDs on the No. 1021/4021. A lit zone LED indicates a
fault or an alarm is in memory which must be cleared (or the INTERIOR turned OFF via the No. 5240 if the Interior
Zone LED is lit and the problem can't be corrected) before the system can be armed. Make sure the exit door is
closed! If no zone LEDs are lit and the Loop Status LED is NOT lit, it is an indication that alarm memory (i.e. panic) is
still present. Activate the FIRE RESET switch downward to clear memory
4. Enter the arming code at the No. 5240 (followed by "0" within 3 seconds if the Interior Zone is to be turned OFF).
The RED Arming Status LED should light steadily (or flash if the Interior Zone is turned OFF). The Perimeter and
Interior Zones arm 'immediately and the Entry/Exit (Delay) Zone's exit delay period begins.
If a three second steady buzz sounds at the No. 5240, it indicates that arming is being attempted with a faufted
zone. ff the fault is in the Interior Zone and the "0" key is depressed during the 3 seconds, the buzz will cease and
the RED Arming Status LED will remain lit. If the buzz continues to its conclusion, the Arming Status LED will not
stay lit and the system was not armed!
5. If leaving the premises, depart before the exit delay period ends, via the entry/exit door.
l
To Disarm Burglary System:
1. When entering the premises, enter only via the entry/exit door. A steady buzzing will sound (at a No. 5240) dur-
ing the entry delay period. Go directly to a No. 5240 and enter the disarm code.
2 If already within the premises, enter the disarm code at a No. 5240.
3. Observe if any of the ZONE LEDs on the No. 1021/4021 are lit (will be lit if an intrusion alarm has taken place
during the armed period). If the fault conditions are no longer present, operation of the FIRE TEST/RESET switch
to the RESET position will turn off the ZONE LEDs.
Note: While the system is disarmed, the GREEN Loop Status and RED ZONE STATUS LEDs will go on and off as
the protective loops open and close during normal operation of doors, windows, etc.
To Test Fife System:
The fire system should be testedat least every week.
Important: If the fire system is connected to'a central monitoring station, they should be alerted before conducting
any test.
1. Push the FIRE TEST/RESET switch onthe No. 1021MO21 upward to Test and hold it. The fire alarm will sound
(loud steady siren), the FIRE LED on the No. 1021/4021 will light and the fire alarm supplemental output trigger will
be produced. During the test, the battery is checked by the sounding of the speakers from the battery Release the
switch: the sound should continue.
2. Reset the system by operating the FIRE TEST/RESET switch momentarily downward to the RESET position.
To Test Burglary System:
The burglary system should be tested as follows at least every month:
Important: If the system is connected to a central monitoring station, they should be alerted before conducting any test.
1. Arm the system.
2. Fault the Perimeter Zone by opening a protected window or other location.
3. The siren speaker in No. 4021 and any external speaker sounds immediately (loud, warbling sound) and the
burglary supplemental output trigger activates.
