Outputs
Four form-C relays SPDT (Single Poll Double Throw) gold-
contact relays are provided for controlling door locks or other
output devices (I.E. sounder, burg panel, phone dialer....etc.).
The energized or ON time for each relay can be configured by
using either time zone control, or programmable pulse time via
the host software.
Relay 1 is defaulted to control the Door 1 lock & Relay 2 is
defaulted for the Door 2 lock. Relay 3 & 4 are used as auxiliary
relays for signaling other devices. All 4 relays are rated at 12
Amps / 28VDC for resistive loads and 6 Amps / 28VDC for
inductive loads (data switching).
NOTE:
Once the relay pole has been used for an inductive load
(including door strikes and magnetic locks) it should not be used for
low current dry circuit applications.
NOTE:
Switching of inductive loads can cause EMI (Electromag-
netic Interference) which may interfere with the normal operation of
other equipment.
To minimize premature contact failure and increase system
reliability, contact circuit protection such as the S-4 suppressor
is required. Locate this device as close as possible to the Door
Strike / Maglock.
