OVERVIEW
NGA-501 is an Analogue Addressable Manual CAll Point,
designed and manufactured comply with EN54-11, compatible
with Nortech Addressable Control Panels. With its enhance
commuication mechanism the typical response time, when in
alarm is approximately one second, depending on the number
of call points connected to the device loop.
A bi-colour LED flashes Green when the unit is interrogated by the control panel and is illuminate Red
when in alarm. The command to illuminate the Red LED is emitted by the control panel in response to
activation of the individual call point thus confirming that the alarm signal has been received at control
panel.
The unit is supplied complete with hinged flap which protects the trigger element from accidental activation and reduces malicious activations as two actions are required in order to activate device. this
unit can be booth surface and flush mounted and it can be easily reset using the supplied key after activation.

The NGA-401 Analogue Addressable Photoelectric Smoke
Detector have been designed to be fully compatible with the
Nortech Global range of intelligent control panels.
Compliant to EN54-5 and 7, the NGA series detectors are available in Optical, Heat and combined Smoke/Heat detector
versions.. Optionally they can be fitted with a short-circuit loop
isolator.

The 317 Series addressable detectors are designed to work with
Avani panel. They have dual LED’s for visual indication. The
LED’s are blinking in normal operating condition while the steady
state is indicative of fire status.
The RE317D-SL is a low profile analogue addressable smoke
detector having a unique optical chamber designed to sense
smoke produced by wide range of source of combustion. The
detector sensitivity can be programmed via FACP. It has a
unique drift compensation feature where in detector monitors the
sensitivity based on environmental conditions.
