Det-Tronics EQ3750ASH EQP Addressable Smoke & Heat (ASH) Module - Manual (Page 3)

4.2 95-8654 3
Class X is intended for use in a multi-zone system and
requires that the first isolator on each leg be installed
next to the ASH Module, within the same enclosure. In
addition, an isolator is needed between each zone as
illustrated in Figure 4. Alarm receipt capabilities in the
other zones shall be maintained during a single open,
single ground, wire-to-wire short, or open and ground.
Note
the isolator has an operating temperature range
of +32°F to +100°F (0°C to +38°C). this means
that, for Class X installations, the enclosure
temperature will be rated to +100°F (+38°C) max.
Reference Table 1 for further details on the performance
requirements for SCLs as defined by NFPA 72.
LED INDICATORS
LEDs on the front of the ASH Module are provided for
indicating device status conditions. There are 6 LED
status indicators (Power, ASH Module Fault, Loop Fault,
Loop Device Fault, Ground Fault, and Alarm) located
on the front panel (Figure 5). Refer to Table 2 for a
description of the LED indicators.
MOUNTING
The ASH Module can be DIN Rail or Panel mounted.
