Edwards Signaling ANSREM Remote Microphone - Manual (Page 2)

2 / 2 P/N 3101182 • REV 02 • REB 28FEB13
Wiring instructions
Refer to the wiring, terminal designation, and application
diagrams that follow.
1. Run 3-pair shielded wire (22 AWG minimum) from the ANS
master panel to the ANSREM remote microphone location.
2. Mount the ANSREMSUP supervision card in the ANS
master cabinet, using snap-track.
Attach snap-track to the ANS master cabinet as required. The
supervision card may already be factory-mounted and wired.
3. Make the wiring connections shown in Figure 1.
4. Verify correct installation of the end-of-line resistor (EOLR)
on the ANSREM.
Each module is shipped with an EOLR installed. When the
system has multiple ANSREM units, verify that the EOLR
is installed on the last unit only.
5. Apply power to test the system:
a. Test the ANS master microphone.
b. Test ANSREM remote microphone.
6. Place the panel in alarm and retest the ANS master
microphones:
a. Ensure that the tone and message are broadcast.
b. Test that keying the microphones overrides any
automatic message or tone.
Figure 1: Wiring the ANSREMSUP
(1) All wiring from ANSREMSUP is power-limited. All wiring must be
routed to maintain minimum spacing from any nonpower-limited
wiring.
(2) When circuits are power-limited, use power-limited cable as
detailed in the National Electrical Code, Article 760, such as FPL
or FPLP type cabling.
(3) Battery cabling is nonpower-limited. Do not route any power-
limited wiring within 1/4 in. of the battery cabling.
Figure 2: Wiring the ANSREM
(1) All wiring is power-limited.
(2) The ANSREMSUP must be mounted in the ANS enclosure or in
another UL Listed cabinet within 20 ft. and connected using conduit.
(3) The ANSREMSUP must be mounted using metal standoffs or an
earth ground connection must be made to TB2-7.
(4) Maximum line resistance is 100 Ω per line: approx. 5,000 ft. using
22 AWG. Maximum line resistance also depends on the number
of devices.
2 ANSREMs = 100 ohms max. line resistance
3 ANSREMs = 80 ohms max. line resistance
4 ANSREMs = 65 ohms max. line resistance
5 ANSREMs = 50 ohms max. line resistance
Using more than 5 ANSREMs is not recommended
(5) EOLR is a 6/3 SIP 10 kΩ resistor network. Install EOLR on the
last ANSREM only.
(6) Terminate the cable shielding at the ANSREMSUP. The shielding
must be continuous from the ANSREMSUP to the last ANSREM,
but must not be terminated on any ANSREM card. Join the
shielding at each cable break, but do not land the shielding on the
ANSREM card.
