1.4.3 UL Requirements

If installed in accordance with these requirements, the Model 4821/4820 is UL listed for

Grade A Mercantile, Local Police Station Connect with Basic Line Security, and Grade B and

C Central Station Service.

Follow the requirements below if you are installing a UL listed application. See Section

1.4.3.1 for Household Fire and Burglary Warning System installation requirements. See

Section 1.4.3.2 for Grade A Mercantile installation requirements.

1. The Model 4860C (commercial) or 4860R (residential) touchpad must be used. Each

SBUS must have at least one touchpad connected (minimum of two touchpads per instal-

lation).

2. Entry delays must not be longer than 45 seconds. An exit delay must not be longer than 60

seconds.

3. All panic zones (including touchpad panic zones) must be programmed as silent and invis-

ible.

Note: Silent and invisible reports can be seen by pressing status or reviewing the event history.

4. The Audible Trouble Alert When Armed option (programmed in Area Menu) must be

selected.

5. Do NOT select the following optional features:

Automatic closing or opening (programmed in the Area Menu)

Swinger Bypass Timeout (programmed in Area Menu)

6. Partitions are allowed in UL burglary installations only if the protected premises falls

under one ownership and the operation of a single authority. An example of an acceptable

installation is a common building operated by one company which may need to subdivide

the system to allow independent entry and exit. A strip mall is an example of an applica-

tion that would

not

be allowed in a UL installation. Partitioning cannot be used for fire

zones. (See Item 9. below for additional information about partitioning.)

7. If the cross-alarm feature is used, it must be used only by detectors that share a common

field of view.

8. A complete functional checkout of the system must be performed any time the system is

programmed or reprogrammed. (Zone bypassing or other temporary changes necessary for

troubleshooting are an exception to this requirement.)

9. Bells must be the primary source of alarm annunciation. Speakers can be used as an addi-

tional source. Grade C Central Station installations are an exception; bells are not required

in these installations. In a multi-partition system, bells must be protected by a

24-hour circuit.

10. Opening and closing signals must be enabled in a Central Station installation.
