Recommended Wiring
Figure 4 shows the recommended wiring for an EVD-2 system with two additional EVD-R remote pickups. (All wiring should be as specifi ed in
Table 1 or with UL listed equivalents.)
1.
Cable clamp knockout locations are shaded. Be sure to remove clamp from base and to cleanly knock out cable openings in the cable
clamp before feeding wire through the clamp.
2.
Without a safe contact, the EVD-M requires the standard, factory installed, cable clamp, (Potter #5280104) for the confi guration shown in Figure 4.
3.
If a safe contact is not connected, the factory installed jumpers on pins 4-5 and pins 7-8 of the EVD-R must not be removed.
4.
Wiring to or from remote pickups must be UL listed, shielded, twisted-pair cabling, (See Table 1). The EVD-R remote pickup network
wiring must not exceed 2000 feet.
5.
Connections to UL listed control unit via UL listed, high security cable, or alternates (See Table 1). See Figure 5b & 5c for 4 or 6 wire
installation wiring.
6.
Only the last EVD-R remote pickup requires the 10K Ohm, 1% end of line resistors. Remove the factory installed end of line resistors
from all other EVD-R's and the EVD-M.
7.
Connections to dry contacts from any UL listed safe contact. Last EVD-R is the preferred unit for connections to the safe contact. However,
all EVD-R remote pickups accept safe contact wiring. Additional safe contacts can be wired into other EVD-R remote pickups, the EVD-M or
a UL listed tampered junction box. If the safe contact is wired into the EVD-M, use the alternate cable clamp. (Potter #5280105)
8.
The EVD-M must be connected to a UL listed control unit or power supply capable of providing nominal 12 VDC and standby power. 72
hours of standby power is required for bank vault alarms. 4 hours of standby power is required for mercantile alarms.
9.
Connections to remote test annunciator or RTA and/or connection of dry contacts from any UL listed central station test unit. Refer to
Figure 5 for detailed information on annunciator and remote test interconnections.
10. Terminals 1-12 on EVD-R are power limited.
11. Terminals 1-15 on EVD-M are power limited
