ページを印刷するPerimeter, interior and Entry/Exit (Delay) Zone LEDs (RED): These LEDs indicate the status of their respective zones.
A lit LED indicates that a loop is in a fault condition. Even when the Interior Zone is OFF, that zone's LED will still indicate
status. These LEDs also provide a memory of alarm if a loop is faulted in the armed state and the fault restores. This
memory remains until the FIRE TEST/RESET switch is moved momentarily to RESR:
ENTRY DELAY OFF (INSTANT ON) LED (AMBER): This LED lights to indicate that the entry delay has been set to zero
by activation of the ENTRY DELAY switch to OFF (INSTANT switch to ON).
m
A.C. POWER LED (GREEN): Indicates that A.C. Power is present at the unit's input terminals.
Keypad, No. 5240: (See Diagrams 3 and 4)
This keypad is integral to the No. 4021 and is remotely located for the No. 1021 and optionally for the No. 4021.
Keys 1-9: These are used to enter the 4 digit arm/d&am/panic cutoff code.
Note: Audible panic cutoff is immediate when the code entry is madd while the system is armed and occurs 3
seconds after code entry when the system is disarmed.
KEY 0: This key is used to turn off the interior Zone if it is depressed within 3 seconds after the entry of the fourth digit of
the arming code. This is useful when it is desired to arm the system with the premises occupied. The Perimeter and Entry/
Exit (Delay) zones will then provide protection. Subsequent to this action, depression of the "0" key by itself will remove
the Interior zone bypass. The Interior Zone may not be turned OFF after the system is armed. lf it is desired to reapply the
bypass, it would then be necessary to disarm the system and to repeat the initial arming/interior bypass function. A safety
feature exists that automatically restores the Interior Zone at disarming time. This guards against the user inadvertently
leaving the Interior Zone off indefinitely, reducing the level of protection provided.
l

Audible Signals:
STATUS
1. System Disarmed, Protective Circuits open (not ready for arming).
2. System Armed (Arming Status LED on steadily or flashing).
3. System Disarmed, Protective Circuits Intact but Memory or Alarm has not been
cleared by activation of the FIRE RESET switch (not ready for arming). If no
zone LEDs are lit, this is an indication that there had been a prior panic
alarm tripped.
System Disarmed, Protective Circuits intact (Ready for Arming).
No. 4021's Built-in Speaker:
FIRE ALARM: A loud, ste,ady sound.
BURGLARY/AUDIBLE PANIC: A loud, warbling sound.
No. 5240's Buzzer:
FIRE TROUBLE: A pulsating, low level buzzing sound.
ENTRY WARNING: A steady, low level buzzing sound that is activated during the entry delay period.
ATTEMPT TO ARM SYSTEM WITH FAULTED ZONE OR ALARM IN MEMORY: A three second steady buzz will be

. . .
activated after the arming code is entered. If the fault is in the interior Zone and it is bypassed, the sound will cease ancl
the system will arm. This sound serves to warn the user that the system will not be armed (because of the fail-safe
arming feature) unless the fault is corrected. The LOOP STATUS LED will be OFF (disarmed, not ready for arming).
The user should clear the faulty zone or alarm memory and then arm the system.
AUXILIARY POWER FUSE OPEN: A pulsating, low level buzzing sound if a No. 633 End-of-Line Relay Module is
used in the fire circuit and the auxiliary power fuse opens. In effect, a fire trouble condition has been detected (See
Item 'Id") under the description for the FIRE LED.
