FirePro Aerosol Containers
Aerosol releasing devices made by different manufacturers differ from each other in their
power requirements and therefore require different interface modules.
The TLA-44 module is intended to work with FirePro aerosol units. It is available in two
configurations that allow for connecting either a single module or up to four modules.
•
TLA-44/1 – allows activation of a single module
•
TLA-44/4 – allows activation of up to four modules
Activation is simultaneous to all aerosol devices connected to the TLA-44. The module's
output lines to the aerosol devices are supervised for open circuit.
The TLA-44 is intended to be installed in the same protected space as the aerosol
devices.
The TLA-44 may be connected to outputs with level activation or reversed polarity
activation.

A Typical Application – Extinguishing and Electricity Disconnect
The following example shows a TSA-1000 that is configured to activate extinguishing by
cross-zone of zones 2 and 3, or activation of a manual extinguishing call point on
zone 4; activating an extinguishing release sign on output 2; activating an evacuation
horn on output 3; triggering electricity disconnect by relay RL3; and connection of a
pressure switch to supervise the extinguishant pressure on zone 1.
Figure 22 shows a system that was configured as follows:
•
Relay 3 – activated by cross-zone (
A
) of inputs 2 and 3, or input 4; not delayed;
unsilenced
•
Input 1 – pressure switch input (
Ξ
)
•
Inputs 2 and 3 – standard detection zones (
d
); no delay
•
Input 4 – pushbutton input (
P
)
