OPTIONAL DISCRETE RELAY PCB’s #’s 10-0222
Important!
10-0222 PCB’s may only be installed into motherboard position P3.
The optional
Discrete Relay PCB
, shown in Figure 3.7, adds six 5 amp form C relays.
Each relay is associated to one of A1, A2 or A3 for channel 1 or 2. Many ViewSmart
200 applications utilize the standard equipped Relay 1 / Relay 2 (see section 2.3.1) and
do not require optional discrete relays for each of the 6 alarms events (2 A1’s, 2 A2’s & 2
A3’s).
All mechanical (dry contact) relays are rated at 5 Amp for 28 VDC and 250 ~VAC
RESISTIVE
loads. IMPORTANT: Appropriate diode (DC loads) or MOV (AC
loads) snubber devices must be installed with inductive loads to prevent RFI noise
spikes.
AC or DC power supplies to relays on the 10-0222 Discrete Relay PCB option must be
the same for each relay. Example: 24VDC should not be the power switched by one
relay and 115VAC by others.
