combination smoke and heat detector multi detector 4 wire smoke heat alarm sensor for fire alarm system
General Description
The detector is a combined smoke and heat detector
with photoelectronic sensor and heat thermistor
together. This detector is designed to provide open
area protection and to be used with most security
alarm control panel.
Two LEDs on each detector provide local 360° visible
alarm indication. They flash every six seconds
indicating that power is applied and the detector is
working properly. The LEDs latch on in alarm. The
detector can be reset only by a momentary power
interruption.
The detector that initiated the alarm condition will
have its red LED and relays latched until reset by
panel.The detector combine a photo electronic
sensing chamber and a temperature heat detector.
