Alarm button ІРТС-1 (alarm button) with lock, designed to generate an alarm signal when danger is detected. It is used with OPS technical means that respond to the activation of a detector included in the PPC alarm loop and activated by a person who detected an alarming situation or was attacked.
IRTS-1 has a plastic case, consisting of a base and an elastic button. In the center of the button there is a cylindrical hole for controlling the position of the pusher. On the edges of the base there are three holes with sealing cups for fixing the detector on the object. On the back of the base there is a screw terminal block for connecting the detector to the loop of the alarm system, which works on a break.
In standby mode, the terminal block contacts are normally closed. When you press the button with your hand or foot, the contacts are opened - the detector switches to the "Alarm" mode.
To return the detector to the next mode in the technological hole, which is in the base, it is necessary to insert the technological special key as far as it will go, after which the pusher will be visible in the central hole of the button. The keyhole is sealed with a seal-sticker, which is included in the kit.
The status of the detector is monitored by the position of the red pusher in the central hole of the button: if the end of the pusher is visible, the detector is in standby mode, if not, it is in "Alarm" mode.
