addresses but are under the responsibility of someone
having mutual interest (other than the alarm installing
company). This does not apply to strip mall
applications where each independent business must
have their own separate alarm system.
An example for a commercial partitioned system would
be a business that has an OFFICE area and a
WAREHOUSE area in a building where each area can
be armed or disarmed independently.
Residentially, systems can be partitioned so that the
GARAGE area is armed separately from the HOUSE.
Each of the above examples would be under the sole
responsibility of a single owner.
For partitioned systems, the “Report Delay” must be
enabled (Equipment Simplified Configurations: E05).
This will annunciate the failure to communicate on the
keypads in all partitions.
The bell and power supply must be in a protected area
including partitioned systems.
Grades of Service - U.L. Listed systems
In addition to the general requirements listed above
please note the following:
A. The commercial bell and bell housing will be
required for Grade A local and police station
connect.
B. The commercial bell is required for Grade B central
station.
C. The digital communicator and IP Module is required
for standard line security in local, police station
connected and central station systems.
D. 72 hours of standby power is required for Banks,
Safes and Vaults in case of failure of the mains
A.C.
BURGLAR ALARM (LOCAL)
1. A Listed Local bell such as Ademco Model AD10-
12M bells, Rothenbuhler Model 5110 and Grade A
bell housing shall be used.
2. The maximum exit delay time shall not exceed 60 s
and the maximum entry delay time shall not exceed
45 s.
3. The digital alarm communicator transmitter shall be
enabled in local alarm installations as it provides
indication of low battery transmission following
primary loss of power.
4. One 7 Ah battery shall be used to provide the 4 h
standby time followed by 15 min of alarm. A
minimum 15 min alarm period shall be
programmed.
5. The maximum total current draw from auxiliary,
snapp, and outputs 1 and 2 combined shall not
exceed 1.0A.
6. Bell plus all other loads must never exceed
1.0 Amps.
7. The system shall be housed in the Model 2912
attack resistant enclosure.
8. The bell test shall be enabled.
BURGLAR ALARM (MERCANTILE SAFE AND
VAULT)
1. Same as local burglar alarm above.
2. One 7 Ah battery shall be used to provide the 24 h
standby time followed by 15 min of alarm and
extended power loss of 24 h.
3. The leads providing operating power to the alarm
sounding device shall be electrically and
mechanically protected as required in the
Standard for Installation and Classification of
Mercantile and Bank Burglar-Alarm Systems, UL
681, or the circuit shall be constructed so that the
system is not defeated by cutting or short-
circuiting connections between the control unit and
the alarm housing.
4. If the system makes provision for connection of
vault or safe wiring to the same circuit and to the
same alarm housing used with premises wiring on
the surrounding premises, tampering with the
premises wiring shall not defeat the safe or vault
wiring.
5. All systems shall employ a closed-circuit cable for
connecting the safe or vault to the alarm housing
so that an alarm is produced if the cable is
severed or disconnected.
6. When the system is placed on duty, a timer in the
system shall prevent the turning off, prior to a time
set by the user, of the door protection and of other
circuits that are inoperative during the open
period. The timer shall be capable of covering a
closed period of at least 96 hours (4 days). See
Programming Section.
7. The door protection and other circuits that are
inoperative during the open period shall be
arranged so that they are placed on duty manually
at the time of closing or automatically by the timer
within 30 minutes after closing of the door and
setting of the system for the closed period.
8. The requirements of 6 and 7 may be provided by a
7 day (1 week) timer that will automatically place
the protection on duty not later than 10 p.m. and
remove it no sooner than 6 a.m. the next business
day. These times may be revised if they conflict
with normal business hours of the protected vault
or safe. The timer shall automatically maintain the
protection on duty on Sundays and holidays. An
electrically protected key or combination control
shall be provided for the user to change the ON or
OFF times and to adjust the holiday carry-over as
required. See Programming Section.
9. The main protective circuits, linings, and
attachments on the safe or vault, control units, and
alarm housing shall be of the normally closed
circuit fully supervised type.
10. Systems employing sound-, vibration-, or
proximity-detector systems shall include provision
for testing the operation of detectors and all
associated relays and circuits without sounding
the alarm.
