Description
The Time Limit Module, TL-30U is designed to provide a controlled time
interval from 6 seconds to 10 minutes, after which either a signal circuit is
activated, (such as a municipal alarm) or a signal circuit is deactivated
(such as alarm bells). The module is also capable of repeating the above
operational sequence when a subsequent alarm signal is received in a system
utilizing the Subsequent Alarm Feature.
The module, which is of solid state circuitry, is normally passive, drawing no
power until an alarm signal is received. When this occurs, a binary counter is
activated to control precisely, the length of the desired time limit before
continuing the pre-programmed sequence of system operation. This sequence
could be for silencing audible alarm devices so that the system could receive
and annunciate subsequent alarms. An alternate use would be the sending of an
alarm to municipal headquarters if the alarm source had not been checked or
controlled, or, it could involve the actuation of an extinguishing system.
This time interval is available in two ranges as follow:
a) 6 seconds to 20 seconds
b) 30 seconds to 10 minutes
Standard units are preset for a 5 minute, time-out sequence, but can be
changed by field adjustment.
Note: : Underwriters Laboratories Inc. standards require that when time
limit cutoffs are used with audible devices, they shall operate no less than 3
minutes and no more than 10 minutes.
The module contains a red LED indicator lamp that is illuminated at the end of
the timing period. This lamp will remain on until the module has been reset.
The Model TL-30U module is placement supervised, providing a system trouble
signal upon removal from the system.
The unit is Underwriters Laboratories Inc. listed.
Engineer and Architect Specifications
Capability for precise time control of an output signal either by delaying
actuation or stopping actuation shall be provided by a Cerberus Piezotronics
Time Limit Module, Model TL-30U. This module shall be system interconnected by
a ten-wire jumper plug and harness assembly, and shall be operable with the
system main control panel.
The time in/time out duration period shall be capable of being set at any
precise interval between the time frames of 6 seconds to 20 seconds, and 30
seconds to 10 minutes. This interval shall be controlled by a solid state
14-stage binary counter contained in the circuitry of the module. At the end
of the time interval, a red LED indicator lamp shall indicate completion of
the time cycle, after which a subsequent alarm can be received and processed
in an identical manner. The module shall be reset from the main control
panel.
The model TL-30U shall be Underwriters Laboratories, Inc. listed.

Typical Wiring
Programming the TL-30U
There are two jumpers and one potentiometer on the component board used to
program the module.
| TIME IN/TIME OUT JUMPER* | LONG TIME/SHORT TIME JUMPER |
|---|---|
Determines whether TL-30U will be time in or time out. Connect jumper between common and TO or TI.| Determines timing period LT: 30 sec. — 10 min ST:6-20 sec. Connect jumper between common and LT or ST.
Adjust potentiometer R13 (500K) for the exact time period desired. Cross-
zoning may be accomplished without the use of zone operated relays. The two
zone outputs are fed directly into the TL-30U (terminals 1 and 2). After the
second zone has activated, the TL-30U will time as programmed.
*Time in denotes delay time period before terminal 3 goes high (+).
NOTES:
- When SA-30 or cross zoning are not used, jumper terminal 2 to terminal 1.
- All input/output signals not supervised.
NOTICE: The use of other than Cerberus Piezotronics detectors and bases with Cerberus Piezotronics control equipment will be considered a misapplication of Cerberus Piezotronics equipment and as such void all warranties either expressed or implied in regard to loss, damage, liabilities and/or service problems.
