Manual call point

Manual call points are connected to the

connecting terminal "Manual call point"

(Fig. 59/12). If a manual call point is actu-

ated, the extinguishing process is released.

Normal state = switch open

Manual call point actuated = switch

closed

1 Lines to the system (connection "12")

2 Resistance R

= 470 Ω, 1/10 Watt

3 Resistance R

= 1,8 kΩ, 1/10 Watt

(delivered as such)

Several manual call points can be parallel connected (Fig. 60).
Extinguishing can be released by actuating a manual call point (

Chapter 12

“Spare parts, accessories, consumables, and tools” on page 116

). Release occurs

directly after the actuation and independently of the state of the automated fire

detectors.
Release of extinguishing by actuating a manual call point is suppressed if blocking is

in place.
The alarm message of the manual release must be reset manually using the upper

[Reset]

button (Fig. 61/1).
