Spray Head Placement; Detection System - Plumis Automist Smartscan Handbook

Automist Smartscan ® Handbook v1.2.3

Spray Head Placement

The Automist Smartscan Head is designed to be affixed into a rectangular hole (89+/-2mm wide x 117mm
high) that is at least 57mm deep when using the "old work" clips provided.
If you are installing Smartscan using a BackBox, the hole dimensions are as following: 94mm wide x 119mm
high and 60mm deep
IMPORTANT: The Automist Smartscan head must be located where the spray pattern will not be
obstructed and 750mm clearance is provided around the spray head. The spray head must be installed at a
height of 1300 ± 100mm from the floor.

Detection System

Automist Smartscan's reliability is dependent on the detection system. The system is designed to be
triggered by a correctly installed, positioned, and CE marked, heat alarm (BS 5446-2 compliant) or by a heat
detector (EN54-5 compliant) connected to a fire panel
by feeding its three-wire alarm input cable from a three-terminal relay that is triggered directly or indirectly
by the relevant alarm or detector.
Automist Smartscan is designed to be connected to all three terminals of the relay: Common,
•
Normally Open and Normally Closed. Any wired or wireless fixed-point heat alarm family that
offers such a connection style may be used. A trigger point of 57 degrees (Class 1) is
recommended.
The pump monitors the C/NO/NC connections continuously. In the standby state, the relay must
•
link the Common and Normally Closed wires together. In a fire state, the relay switches, instead
linking Common to Normally Open.
Relays with only Common and Normally Open terminals may also be used but in such cases the
•
Automist Smartscan pump must be customised by Plumis before shipping.
