heat detector 4wire relay contact out home security connection

Smoke/Heat Detector 4 wire DC power supply home security system N/C N/O contact fire detector.
With Relay Output
WT-145
1. GENERAL DESCRIPTION
The detectors are photo-electronic detector uses a state of-the-art
optical sensing chamber. 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. LEDs will be off when a trouble condition exists indicating
that the detector sensitivity is outside the listed limit. The alarm 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.
Heat detector and smoke & heat detector combine a photo
electronic sensing chamber and a temperature heat detector.
