Analog call point with built-in isolator – Detnov MAD-451-I

Description

Analog call point – Detnov MAD-451-I

The MAD-451-I analog pushbutton is designed to be used with Detnov analog fire detection control panels and are, along with detectors, the basics of alarm initiation in a fire detection system.
MAD-451-I pushbuttons are certified according to EN standards 54-11 and in 54-17. They are connected via two wires, to the analog detection loop Detnov. This range of pushbuttons incorporates an isolating circuit against short circuits in the loop.Each pushbutton occupies one of the 250 addresses available on each analog loop and needs to be addressed
with the PGD-200 programmer or directly through the control panel's auto-addressing function. The LED lights up intermittently every time it communicates with the control panel and permanently when it has been
pulsed to generate a fire alarm.
Push buttons use a patented mechanism that provides real action, glass breaking sensation, in its activation. An indicator is displayed (yellow and black) at the top of the window when activated. Reassembles with a key and is ready for immediate reuse, while offering the user the benefits and environmental benefits of a resettable operating device
without using crystals.
Resettable analog call point with built-in isolator for surface mounting. Incorporates LED indicator
status and reset key. Red color. CPR EN certificates 54-11 and in 54-17. Dimensions: 85 x 85 x 55 mm.
