WSD-1 audible signal switch

The WSD-1 acoustic signal switch is designed for use with SA-K, SA-P8, SAO-P8, SAOZ-PK2, SGO-PGZ3, SG-PGW3, and SGO-PGW devices. The switch is used to deactivate the acoustic signal generated by the aforementioned devices.

Description

The WSD-1 audible signal switch is destined for collaboration with:

The WSD-1 switch is used to deactivate the acoustic signal generated by the aforementioned devices. It leaves the visual signal active (in the case of acoustic and visual sounders). For SA-K5, SA-K6, SA-K7, SG-PGW3, SGO-PGW, and SGO-PGZ3 devices, a single WSD-1 switch can be used to deactivate only one device. For the SA-P8, SAO-P8, and SAOZ-PK2 series, depending on where the WSD-1 switch is connected, it can be used either to deactivate a single device locally (WSD-1 connected to a “slave” device) or to deactivate the entire network of devices (WSD-1 connected to the “master” device). The WSD-1 acoustic signal switch is used in fire alarm systems to facilitate evacuation procedures.

Construction

The WSD-1 acoustic signal switch consists of a plastic enclosure with a momentary push button. The push button features an LED indicator. The device wires are connected to terminals located on the switch’s printed circuit board. The acoustic signal switch is wall-mounted using two screws. When an alarm signal is generated by the fire alarm control panel, the connected SA-K, SA-P8, SAO-P8, SG-PGW3, SGO-PGW, SAOZ-PK2, or SGO-PGZ3 devices are activated. The acoustic signal can be deactivated by pressing the WSD-1 switch button. This is indicated by a flashing LED. The LED continues to flash until the alarm signal from the fire alarm control panel is cleared by resetting the alarm condition on the control panel. If the alarm signal is generated again, the relevant devices will be activated again.

Notice The WSD-1 switch is supplied directly from the signaling device connection block. Do not connect an external power source to the terminals of the WSD block.

FAQ

WSD-1 audible signal switch / Find out the most frequently asked questions and answers about this product

Your questions, our answers: Whether you are a new user or a regular customer, our answer database contains a wealth of information to help you better understand our products. Discover the answers curated by our experts.

Where is the best place to mount WSD-1 switch?

WSD-1 switch should be installed in places where persons authorized to turn off the fire alarm signal have access, it is not permitted that the WSD-1 switch is mounted in places where unauthorized persons have access.

What can be the practical use of WSD-1 switch?

The practical application of WSD-1 makes it easier to conduct rescue and evacuation operations. At the time we turn off the sound signal, leaving at the same time the optical signalon it is possible to issue commands that are not deafened by the fire alarm signal.

Is it possible to turn the acoustic signal on again after it has been turned off by WSD-1?

Unfortunately, no, the idea of ​​operation of the WSD-1 switch is based on the principle of "stable" switching off the signal until the fire alarm is cleared (in practice, switching off the power supply to the alarm line). The WSD-1 switch has an electronic system in its structure that performs the "latch" function; only turning off the voltage unlocks the latch.

Should an additional cable with a cable junction box be provided to the WSD-1 switch?

No, additional protection is not required for the WSD-1 switch, because the alarm device to which the switch is connected, is connected to the FAS installation through a cable junction box of required fire resistance with a built-in fuse.

What is the WSD-1 switch used for and what are its usage principles?

The WSD-1 switch is a fire alarm audible signal switch. It is intended to be used together with acoustic and optical alarm devices. Thanks to the use of the WSD-1 switch a user can turn off sound of an alarm device with an optical signal on. The WSD-1 switch is connected straight to device terminals. It is not necessary to fix a switch through a fire resistant cable junction box. There applies the following principle: one alarm device – one WSD-1 switch.
