The Edwards 3-PSMON is the EST3 Power Supply Monitor Module — the local-rail half of an EST3 power supply assembly. First, the matching 3-PPS, 3-BPS, or 3-BBC power supply card mounts to the back of the chassis. Then, the 3-PSMON mounts on the local rail and distributes 24 VDC power to other LRM cards.
In addition, the 3-PSMON provides two auxiliary 3.5 A power outputs via easily accessible terminal blocks. As a result, integrators can tap auxiliary 24 VDC for ancillary loads without splicing into the rail.
Edwards 3-PSMON features
- Mounts in one local rail module space; supports one control/display module above it
- Two auxiliary 3.5 A 24 VDC outputs per supply, terminal-block accessible
- Terminal capacity 18 AWG to 12 AWG (1 mm² to 2.5 mm²)
- Reports specific diagnostic codes to the 3-CPU for faster troubleshooting
- Trouble codes include: battery trouble, aux power overload Circuit 1 or 2
- Replaces the monitor module half of a 3-PPS/M, 3-BPS/M, or 3-BBC/M assembly
How it pairs with the power supply card
Each EST3 power supply ships as two assemblies. Specifically, a switch-mode power supply card mounts to the chassis. Then the 3-PSMON monitor module mounts to the local rail and feeds it. As a result, replacement parts can be ordered separately when only the monitor half needs service. Furthermore, up to four power supplies can parallel on a rail for up to 28 A available power in a single enclosure.
Listings
The 3-PSMON is part of the UL 864-listed EST3 power supply system when paired with a 3-PPS, 3-BPS, or 3-BBC card and installed in a listed EST3 cabinet. The EST3 platform is listed to UL 864 (Control Units and Accessories for Fire Alarm Systems), ULC-S527, and additional categories per Edwards datasheet 85010-0059.
